grblhal / lpc176x

grblHAL driver for LPC1968 and LPC1769

LPC176x grblHAL driver

A GrblHAL driver for NXP LPC1768 and LPC1769 processors.

Loosely based on the official grbl-LPC port.

See the Wiki-page for compiling grblHAL for instructions for how to import the project, configure the driver and compile.

Available driver options can be found here.

Update 2020-12-11:

• Added initial board map file for Bigtreetech SKR V1.3 Turbo board.

Update 2020-11-21:

• Added initial board map file for BTT SKR V1.4 Turbo board.
• Added polling of limit switches, enabling hard limits is now possible.

A build option for creating a Firmware.bin file that can be used for programming via the Smoothieboard DFU-bootloader has been added to build configurations.
Select the BL_0x4000 configuration from the build tool dropdown to build, and programming can then be done via SD card transfer:

Firmware.bin is found in the BL_0x4000 project folder after a successful build.

Update 2020-01-01:

• Added board map file for Ramps 1.6 on Re-ARM board hacked for programming via Segger J-Link. Improved pin assignment handling and fixed some bugs. USB comms and SD card seems to be working ok for this board, however only limited testing done.

Update 2019-08-08:

• Changed IDE to MCUXpresso v11 and linked against LPCOpen development platform libraries. I2C EEPROM on OM13085 LPCXpresso board and SD card supported.

Board maps:

	N_AXIS	Ganged axes1	EEPROM2	SD card	Modbus	I2C Keypad	Encoders	Digital I/O	Analog I/O
Generic	max 5	no	external	external	no	no	-	-	-
BOARD_RAMPS_16	max 5	no	external	external	no	no	-	-	-
BOARD_BTT_SKR_13	max 5	no	external	onboard	no	no	-	-	-
BOARD_BTT_SKR_14_TURBO	max 5	no	external	onboard	no	no	-	-	-
BOARD_MKS_SBASE_13	max 5	no	external	onboard	no	no	-	-	-
SMOOTHIEBOARD	max 5	no	external	onboard	no	no	-	-	-

¹ Each enabled reduces N_AXIS with one. Currently the board map file must be edited to enable ganged/auto squared axes.
² I²C EEPROM (or FRAM) is optional and must be added externally. FRAM is recommended when the Odometer plugin is added to the build.

lpc176x's Issues

SKR V1.3 - Error 9 After compiling and flashing to board

I've successfully compiled and created a firmware.bin file, it flashes to my board, a BTT SKR V1.3 board with LPC 1768 chip. My computer sees and assigns a com port, however i cant connect to the board. I receive an error 9 and i cant connect. Ive tried pronterface and also the machine control panel in Simplify3D. Ive reviewed all the files in MCUXpresso and I dont see where I can verify the baud rate, however no baud rate that i choose in pronterface allows me to connect.

Invert A/B (ganged y) stepper enable pins?

When using a ganged Y config with an SKR 1.4 it is not possible that i've found to invert the A or B steppers enable pins which makes them inoperative,

Hopefully im missing something but thus far i have not found anything.

Currently my $4 is set to 7 if that helps

Typedef struct xbar -> bit

A submodule update did remove the attribute "bit" from

typedef struct xbar

but it is still in use.

https://github.com/grblHAL/LPC176x/blob/5d65d9b342af32eed3147aa15b5e6efb65556dde/src/btt_skr_1.x.c#L127C14-L127C15

Laser head is slowing down during rastering

Hi,

another "problem" when engraving/rastering with higher speeds the laser head is slowing down considerably, is this normal ?
I thought that laser head should be running with consistent speed and only change the power of the laser.

See video below

Probe Pin BTT SKR 1.3

btt_skr_1.3_map.h - default probe pin is 0.12, should this be 0.17?
(might just be me, but I cant find a 0.12 on the lpc1768)

Laser and spindle on MKS Sbase V1.3

Hey there,
Since two days I am trying to get a firmware ready based on grblHAL for the MKS Sbase v1.3 which is capable of using two different PWM pins for controlling laser and spindle. I think I am missing something or just being too stupid to put the pieces together.
I think I found the relevant parts in the respective *.h files but I was not able so far to get the things working.
From the mks_sbase_map.h the relevant part is to my mind the following:

_// Define driver spindle pins

#if DRIVER_SPINDLE_PWM_ENABLE
#ifdef SPINDLE_PWM_PIN_2_4
#define SPINDLE_PWM_CHANNEL PWM1_CH5 // MOSFET3 (P2.4)
#else
#define SPINDLE_PWM_CHANNEL PWM1_CH6 // BED MOSFET (P2.5)
#endif
#define SPINDLE_PWM_USE_PRIMARY_PIN false
#define SPINDLE_PWM_USE_SECONDARY_PIN true
#else
#define AUXOUTPUT0_PN 2
#define AUXOUTPUT0_PORT port(AUXOUTPUT0_PN)
#define AUXOUTPUT0_PIN 4
#endif_

I also found in the config.h the part for the definition of the number of spindles/PWM devices:

/*! \def N_SPINDLE
\brief Defines number of spindles supported - minimum 1, maximum 32.
*/
#if !defined N_SPINDLE || defined DOXYGEN
#define N_SPINDLE 2
#endif

Here, I suppose that I should increase the number to 2...

And then finally the part of my_machine.h:

#define SPINDLE0_ENABLE SPINDLE_PWM0
#define SPINDLE1_ENABLE SPINDLE_PWM1
//#define SPINDLE2_ENABLE SPINDLE_PWM0_CLONE
//#define SPINDLE3_ENABLE SPINDLE_NONE
// **********************

But now I don't understand how to tell the code that I want to use two different PWM pins for the devices and also were to remap the respective pins accordingly. Also the PWM-Channel thing form the mks_sbase_map.h is unclear for me. And the final question for me is how two switch between the two PWM devices in a respective controlling software?

I am really confused at this point and your help is more than aprreciated.

Thanks you and best regards

Florian

Spindle enable and direction not changing state

Hello, the SKR 1.4 turbo has pins 1.23 and 1.24 defined as spindle enable and direction. I'm using I/O sender edge i can select turn on the spindle CW or CCW and pins 1.23 and 1.24 do not change state. Between the pins and +5V I get 5V and between pins and ground, i get 0V So the pin is Low/ground all the time. Flood and mist seam to work in the same EXP1 connector

Second serial interface

Hi, GRBLHAL runs very nice on the MKS BASE 1.3, thanks for this driver and all the help to get it starting.
I've got a last question. I would like to create an external jogger and need a second serial port for this. There is an expansion port on this board, that is used for the external TFT. It uses serial communication, so there must be a pair of RX/TX signals, but my attempts all failed until now. Is there a possibility to access the second serial port with GRBLHAL ? This would make it much easier to communicate with the board.

LPC1769 pins to SKR 1.4 Turbo

Hi @terjeio, thanks alot for your work here 😊
I've spent a little time trying to get my head round how the pin mappings work. I've come to realise that it is the pins of the actual chip and not the board is on.

I've have searched high and low for a pinout diagram that has the chip number along side the board pin number. I'm not a wiz at programming, I do as much reading as I can first but this is quite in-depth.

If I choose to use the skr 1.4 turbo pin file, does that mean I can just use the step/direction/enable pins for the respective axis straight to my external drivers? I also wanted to control relays possibly off the spare pins. This is another reason I wanted a diagram of the pin to pins. I am also goin to have 2 x and 2 y motors and needed some help with those pin assignments too..

If you or anyone can help, or if there is an in-depth tutorial on setting up grbl on an lpc1769 chip I would be eternally grateful.

Thanks again for all you work here.

Autosquaring with Re-Arm and Ramps 1.6

Hello, I am trying to convert my cnc maschine (mpcnc) to grblHal but I am struggeling with ganged axis / auto squaring.
I want to use dual endstops for x and y axis and so my question is how to define that grbl uses the limit_pin_max as a second limit_pin.
Is it enough to just enable #define x_ganged and #define x_auto_square in the my_maschine.h file or do i have to change something else, because on the frontpage it says that the board map file has to be edited.

Thanks in advance!

QEI ON LPC1769

I'm curious if it is possible to get QEI or spindle sync working on LPC1769 board like the SKR turbo. I see that the chip itself does support QEI.

Error compiling for board SKR v1.4 turbo

I just downloaded and trying to compile grblHAL with LPCXpresso
I have my_machine.h
#define BOARD_BTT_SKR_14_TURBO
I have Build Configurations BL_0x4000

I'm getting "make: *** [src/flash.o] Error 1"

When I look at flash.c
I have an error here. It says "initializer element is not constant"

Question/clarification - PWMs

Sorry if this is a bit of a rudimentary question, but I haven't been able to sort it out just yet.

Background: for lack of anything better to do, I have been working on integrating a BLTouch probe on SKR 1.4 Turbo. I have it sitting around so I thought I would give it a try. It needs a PWM, which are typically defined by servo angles for it to deploy/retract.

I have it defined for PWM1_CH1 and secondary_pin. I have an init statement in driver.c, but it is unclear to me how the period and width parameters are used. It looks like the spindle period pwm defaults to 5000Hz. Is the width value simply the duty cycle for this period (0-100), or is it defined by the pwm resolution value (32bit?)?

Can't seem to get SKR 1.3 + TMC 2209 to work, can anyone help?

Im trying to get this board to work with my 3018 style CNC but I can't get the motor to turn. It will stutter 3 times when i try to move the X axis and then just stop until unplug the power and replug it back in. I had a pretty hard time learning how to compile but manage to get a firmware.bin and uplaoded to the board but Im unsure if I did it correctly.
Here is what I changed

Here is what I get in Universal GCode Sender

I had to change the following to get no alarms

$17=4

everything else I think is default.

Device Descriptor Request Failed

Hi,
I'm having an issue with windows and BTT SKR 1.3.

Everything was working fine previously, the machine had been turned off for maybe a week.

Now when I plug the usb cable into the computer I get a popup saying the usb device malfunctioned.
In Device Manager it is labelled as "Unknown USB Device (Device Descriptor Request Failed)".

Is this a software issue?

I've tried 3 different cables, and the board is also currently sitting on the workbench completely disconnected, and now pwered from usb, I've also tried powering from the 24v PSU.

This was on a Windows 10 computer, I've also tried a windows 8 and got something similar.

Thanks,

SKR V 1.3 - Set Digital Pin 2.0 Low on reset

Ive successfully set up a laser to run off of the servo pin 2.0 and compiled the firmware to work in that way, instead of the bed. My laser needed 5 volts instead of the 12 volts. However, the digital pins on the LPC1768 are by default, as Ive read in the datasheet, set to high. This results in a voltage of +- 2.36 volts on pin 2.0 on reset. I can turn the lasermode off and on using $32, or inside lightburn, which sets the pin 2.0 voltage to 0.00, to low.

Id like this pin to use the pulldown resistor internally to be set to low on reset. Can you point me in the direction so that i can accomplish this? Upon reset, with the 2.36volts on the 2.0 pin, it causes the laser to turn on. With a low voltage of 0, i could then just turn in on in low power mode with the button as intended. This way the laser wont just turn on when i plug in the board and i wont have to always have lightburn turn on and then turn on the lasermode to set the pin 2.0 voltage to low as is needed.

how to modify PINs ?

Hi again, just a dumb question, how can i modify pin outputs ?

According to PIN map for SKR 1.4T [https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/blob/master/BTT%20SKR%20V1.4/Hardware/BTT%20SKR%20V1.4PIN.pdf]
I suppose that it should be done in btt_skr_1.4_turbo_map.h ?
I want to use PIN 2.7 for PWM output to CO2 laser PSU.
Because i have one SKR 1.4T board where all other MOSFETs are fried :-)

And it is possible to control outputs thru G code ?

Help needed with compiling please

Hi there,
I was wondering if someone could help me,
I have a k40 which I’ve installed a skr v1.4 turbo board into and have it running with smoothieware but I am looking to install grblhal because it looks like a better firmware .
The problem I am having is that I am falling at the first hurdle and can’t for the life of me figure out how to compile it via platformio.
I have opened a new project with the relevant mcu selected which is LPC1769 and I have downloaded the grblhal core and the driver lpc176x files and then from there I don’t really know where I should be going.
So if there is any could write ups that are easy to follow or YouTube videos that could help please point me to them,or maybe someone has the firmware already compiled and don’t mind me trying it that would be great .
I have setup marlin before on 3d printers and smoothie as I said .
Thank you Dazz

No serial access

I'm not a developer and only used the Arduino IDE until now to compile and upload GRBL.
Compiled GRBLHAL with MCUXpresso IDE v11.3.1 [Build 5262] [2021-04-02] under Ubuntu 20.04. After changing the MCU to LPC1769 and the path in main.c to grbl/grbllib.h it compiled without error but a few warnings. Flashing the BTT SKR 1.4 TURBO worked but I'm not getting USB-Serial Connection to the board.
When flashing the binary provided in Issue #1, I'm getting USB-Serial connection.
What am I doing wrong?

Probing not reporting

SKR 1.4 Turbo. Probing operations work, but the "PRB" acknowledgement with position is not returned. I have verified that DEFAULT_NO_REPORT_PROBE_COORDINATES is commented out. The PRB line can be retrieved with $#.

SKR 1.4 turbo endstop pullup not working

Hello, I am unable to make the end stop working at SKR 1.4 turbo. The end stop looks like there is no pull-up on the pin the default voltage on the input pin is 0V. I tried changing the settings to $18 but still no voltage. If I invert the pin status and connect 3.3V to limit input it is detected as pressed endstop. Thanks a lot.

skr 1.3 and 1.4 turbo problem axis Y Z

Hi
With the latest firmware I can't get Y and Z axis to move on skr 1.3 and 1.4 turbo while X axis works smoothly, I haven't changed anything in config.h, where am I wrong?

compilation issues, possible makefile export branch?

hi, very excited to find this project, especially as it looks like i will technically be able to build it for my skr 1.3, however i have not been able to get it to work, the arduino library method just says no libary found, and trying to load it into a fresh version of eclipse cdt embedded wasn't able to import the project properly at all. would it be possible to do an export of a makefile setup, which should be trivial from eclipse from what i have read.

PlatformIO/Makefile compilation

I've been trying to compile this project without installing a huge IDE that I need once-twice a year and Arduino reports "no libraries found".

Can you please give the full compiler flags, declarations and linker options that you have so I can write some kind of a nicer build method? Maybe even a GitHub Action template that people can fork and maintain their builds nicely.

I came up with this platformio.ini:

[platformio]

warnings on compile

Are this anything to worry about?

Digital I/O ?

Hello, do you plan to add support for some Digital I/O ? On the EXP1 and EXP2 (SKR 1.3 Turbo) should be some pins whats are unused.

TMC2209 on SKR E3 Turbo report incompatible driver

I'm trying to get E3 Turbo to work, which has soldered TMC2209s but after writing a map and setting TRINAMIC_ENABLE 2209 I get via serial:

The weird thing is that for a moment it worked but somehow didn't compile the trinamic code (no $338 setting available).

Ideas? Maybe the EEPROM is corrupted? Can I reset it via an SD card file for example?

Contextual notes: I have both X & Y ganged (MPCNC)

Compile Error

hi,
I am currently trying to compile a new version and am getting some errors.
Can you fix them?

Thanks

S32 alternatives ?

Hi,
I'm a MAC user and there is no S32 Studio available for my OS. Is there any possibility to compile this outside S32 ? I need to compile the sources for my MKS Base 1.3 and cant find any possibility on a Mac. Installing Windows in a VM is no Option, since i would need to buy Windows first and being a student, thats no option.
What can i do ? If there is no possibility, could someone please compile it and upload the image file ? Hope you can help me.

TMC5160 on SKR 1.4?

Out of curiosity, what is the limitation to enabling TMC5160 drivers on the SKR1.4(turbo) boards?

where is the upload.ino

For the ones like me that wants to use Arduino ide, where is the upload.ino file? i all repos that i downloaded there is no "example" folder containing this file....
