Code samples for the Tomu board

Tomu Samples

These projects are simple programs for the Tomu. They do various things, and are intended to offer code examples and simple testing to ease your introduction to the Tomu platform.

These are based on the libopencm3 library. To build projects using the Gecko_SDK provided by Silicon Labs, see the gecko-sdk directory.

libopencm3

libopencm3 is an Open-Source lowlevel hardware library for ARM Cortex-M3 microcontrollers (but also M0, M4 are supported and more to come).

Upstream libopencm3 now supports the EFM32HG. The examples located here were modified to support the EFM32HG and tested on the Tomu with a Linux host:

• A USB-Serial CDCACM device example (usb_cdcacm)
• A USB HID mouse emulation example (usb_hid)
• A USB Mass Storage Device example (usb_msc)
• A USB MIDI example (usb_midi)
• A raw endpoint example with a sample python program that controls an LED

Building

1. To compile these, you'll need a cross-compiling toolchain to arm-none-eabi.

• Debian/Ubuntu/... : sudo apt-get install gcc-arm-none-eabi
• Fedora : sudo yum install arm-none-eabi-gcc-cs arm-none-eabi-newlib
• OpenSUSE: sudo zypper ar obs://home:mnhauke home_mnhauke && sudo zypper in cross-arm-none-gcc8 cross-arm-none-newlib-devel dfu-util
• Arch : sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib
• Other Linux : check your package manager, or
• Anything else (Windows, OSX, Linux): https://developer.arm.com/open-source/gnu-toolchain/gnu-rm

2. Fetch the required git submodules:

git submodule update --init --recursive

3. Run make to build all examples

Debugging build issues

It can be helpful to run the build with:

CFLAGS='-v' make

This will show you include paths, commands and more, and may help you to diagnose the issue.

Bootloader assumptions

These examples are compatible with the non-DFU serial AN0042 bootloader. They will run in legacy mode with a DFU-enabled bootloader, such as the one shipped on v0.4 boards. They run from flash offset 0x4000, and do not auto-boot. To get back into the bootloader, reset the board (e.g. by unplugging it and plugging it back in).

If you have a DFU-enabled bootloader, upload programs using dfu-util. For example, to upload miniblink, run:

dfu-util -d 1209:70b1 -D ./usb_hid/usb_hid.bin

If you're using the serial bootloader, upload the binary using XMODEM.

License

The libopencm3 code & examples are released under the terms of the GNU Lesser General Public License (LGPL), version 3 or later.

See COPYING.GPL3 and COPYING.LGPL3 for details.

tomu-samples's Issues

Built binaries don't enumerate when building on Ubuntu 18.04 LTS

I can flash the prebuilt/usb_* images and they work fine, but when I build with the arm-none-eabi toolchain in ubuntu bionic's apt I get images that when flashed just end up doing:

[351788.310188] usb 1-2: USB disconnect, device number 44
[351788.654610] usb 1-2: new full-speed USB device number 45 using xhci_hcd
[351794.010468] usb 1-2: device descriptor read/64, error -110

The compiler version reports:

arm-none-eabi-gcc (15:6.3.1+svn253039-1build1) 6.3.1 20170620

MacOSX (10.13.) usb_simple USBError [Errno 60] Operation time out

any ideas where or how to check/test/fix this?

Create a WebUSB compatible example

• https://wicg.github.io/webusb/
• https://developers.google.com/web/updates/2016/03/access-usb-devices-on-the-web

Ultimately it would be awesome if someone could go to the Tomu website to do a firmware upgrade of their device!

Create smart card emulation type firmware

Capacitive touch issue?

I ran the blinky and blinky-usb code but the capacitive button on the red side isn't working.

When I press the green side it flashes green 10 times as expected.

When I press the red side there is no response. Tomu continues to blink as normal, there aren't any 10x red flashes.

I've looked at this code and it appears to be correct. I'm unsure where / how to debug this?

Port ChibiOS to EFM32HG part

Nobody has got ChibiOS working on a EFM32HG before. Need to create a custom HAL - see http://chibios.sourceforge.net/docs3/hal/index.html

• http://www.chibios.org/dokuwiki/doku.php?id=chibios:product:hal:start
• http://www.chibios.org/

Write something which demonstrates the LEUART

• im-tomu/tomu-hardware#6

Also help with im-tomu/tomu-hardware#10

Add a macro for creating a Toboot header

Toboot has some configurable parameters, including whether to boot the program by default on poweron.

Add a macro to create this header.

API reference: https://github.com/im-tomu/tomu-bootloader/blob/master/API.md#program-header

consolidate this and the tomu-quickstart repository

There seem to be two repositories that share some example code, this one and the repo at https://github.com/im-tomu/tomu-quickstart - IMHO it would be better to have only one repo for each sample code to make sure that changes to the examples do not need to be synced.

Automate Linker Script modification in Makefile

The Makefile currently requires a human to modify the linker script under Gecko_SDK once it's been checked out by make deps.

Automate this.

Check out the make check part of the Makefile for the modifications that are necessary.

Create a "USB Keystroke Prankster" firmware

http://www.jaycar.com.au/usb-keystroke-pranker/p/GE4300

Unleash moments of confusion and panic on unsuspecting victims with what appears to be a USB drive. Simply plug it into their computer and it will either randomly type sentences, engage capslock or move the mouse on their PC. Little switches allow you to control the prank option and a dial will adjust the time delay. It's advisable to keep the frequency low to avoid suspicion. Perfect for pranking your co-worker, friend or family member.

Get a LUFA USB example working

http://www.fourwalledcubicle.com/LUFA.php

LUFA (Lightweight USB Framework for AVRs, formerly known as MyUSB) is my first foray into the world of USB. It is an open-source complete USB stack for the USB-enabled Atmel AVR8 and (some of the) AVR32 microcontroller series, released under the permissive MIT License (see documentation or project source for full license details). The complete line of Atmel USB AVRs and USB AVR boards are supported by the library, as are any custom user boards, via custom board hardware drivers supplied by the user.

• http://www.silabs.com/Support%20Documents/TechnicalDocs/AN0861.pdf - LUFA USB Stack CDC Demo
• http://mgrfq63796.lithium.com/t5/Simplicity-Studio-and-Software/lufa-usb-library-for-efm32/td-p/98913

There also seems to be a LUFA port to the NXP IC that we are planning to use in the "tomu pro" board - https://www.lpcware.com/content/project/nxpusblib and https://github.com/kevinmehall/LUFA-LPC13xx

Create an example using Zephyr on the Tomu

The video signal booster that @antmicro did uses the Tomu device and runs zephyr.

Should be pretty easy to take that and do a little demo on the Tomu.

Move the SDK download stuff to the top directory

So it can be shared between all the sample code.

Figure out the number of USB IDs we need and request them from OpenMoko

We probably need USB IDs for the following modes;

• Bootloader mode
• FIDO/U2F mode
• ? - HID mode
• ? - Serial mode
• ?????

We can also use the bcdDevice value to differentiate modes if they all shared the same VID+PID..

We should track this in the wiki...

Create a FIDO / U2F compatible firmware
