simba's Issues

TCP sockets on ESP

Currently only UDP sockets are supported in Simba. This issue will add support for TCP sockets for the ESP.

how to set remote server addr and port when use mqtt_client

simba project has mqtt_client
in path: src/inet/mqtt_client.c
i read test code try understand how to use it
but i not found how to set remote server addr and port

upgrade latest esp8266 rtos sdk version

http://bbs.espressif.com/viewtopic.php?f=46&t=2349

Http Server do not support POST method

I find those lines in http_server.c file:

/* Save the action and path in the request struct. */
strcpy(request_p->path, path_p);

if (strcmp(action_p, "GET") == 0) {
    request_p->action = http_server_request_action_get_t;
} else {
    return (-1);
}

but, in most cases, POST method is used to submit form, I hope POST method will be implement in simba project.

network_interface_wifi_station_espressif_start hang-up

if wifi ssid or password isn't correct
network_interface_wifi_station_espressif_start will blocked and device hang-up
is there some solution ?

compile error with cpp code

if i use arduino.cpp code like this:

#include <simba.h>

yes, it's a empty file, only include simba.h, then i use

pio run

i got many error message:

Flash driver for ESP

Implement the flash driver for esp to make spiffs work with flash storage. At the same time the flash driver API should be changed to include an erase function and low level read and write functions.

request implement ssl/tls layer

improve data security

if boot ESP12e board, you can see message: formating

if set CONFIG_START_FILESYSTEM = 1
then formating the fs every boot time

ESP32: SPIFFS

Implement support for a SPI Flash File System on the ESP32.

esp12e support ext interrupt, but simba not define exti_device array

is there some quick method to use it ?

PlatformIO release

Simba is a new framework in PlatformIO. Support for ESP must be added to the Scons build script used by the PlatformIO. Also, make sure that the rest of the boards builds.

When all boards works, set a tag and release it to PlatgormIO.

New board: STM32F3DISCOVERY

Port the kernel and the pin and uart drivers to the STM32F3DISCOVERY board.

The board can be bought here.

The port has already been started, but is far from complete.

is that rom size limit ?

JSON module

Include the JSON parser JSMN in the slib package. It has an MIT License.

Support bigger set of the regex syntax

The regular expression module supports most commonly used regex syntax, but there are a few important parts missing. Those should be implemented.

Beginning ('^') and end ('$')of line.
Alternatives ('|').
Groups ((...)).
Multi line to match beginning and end at every newline.

Also, refactor and remove debug prints to reduce the code size and make the code more readable.

Use STM HAL

Use the non blocking interface.

Improve the socket module readability, correctness and functionality.

Improve the socket module readability, correctness and functionality by calling LwIP functions from the LwIP thread and adding poll functionality for recv() and accept().

UDP sockets is a good first candidate to implement the changes for since they are simple.
Continue with TCP sockets.
And last RAW sockets.

Is the new config system working as expected?

Created a config.h file in root folder with the following content:

ifndef CONFIG_H

define CONFIG_H

/* Default system tick frequency. */

ifndef CONFIG_SYSTEM_TICK_FREQUENCY

define CONFIG_SYSTEM_TICK_FREQUENCY 250

endif

When running the frequency is still 100. Maybe I am missing something.

how can i send and recv udp data use one socket

I try to use the UDP protocol for the communication between the client and the server.
The client sends a message to the server periodically, and the server may also send messages to the UDP port, which is monitored by the client.

The client is behand in a NAT server.

So I used two thrd to carry out this operation, a thrd dedicated users to monitor the UDP port data, another thrd dedicated cycle of sending messages.

At the same time, in order to allow the client to send the port and the server to send the port is the same socket, I put this socket is set to the global variable

At the beginning of a simple client to send a message when quite normal, but once the server to respond to a message, immediately went wrong.

I guess it is because socket_send_to and socket_recvfrom will change the thrd_p element of the socket structure.

Do not know how to achieve this kind of demand is better?

//global
struct socket_t udp;

// thrd_1
socket_open_udp(&udp);
socket_bind(&udp, &local_addr);
while(1) {
        socket_recvfrom(&udp, buf, 31, 0, &remote_server_addr);
}

// thrd_2
while(1) {
        socket_sendto(&udp, buf, strlen(buf), 0,  &remote_server_addr);
        thrd_sleep(10);
}

socket_sendto doesn't work for me

#include "simba.h"

static struct network_interface_wifi_station_espressif_t wifi;
static struct shell_t shell;

int main()
{
    sys_start();

    network_interface_wifi_station_espressif_init(&wifi, "SSID", "PASSWORD");
    network_interface_add(&wifi.network_interface);
    network_interface_start(&wifi.network_interface);

    shell_init(&shell, sys_get_stdin(), sys_get_stdout(), NULL, NULL, "admin", "admin");
    shell_main(&shell);

    uint8_t buf[16] = "hello";
    struct socket_t udp;
    struct inet_addr_t local_addr, remote_addr;
    socket_open_udp(&udp);
    inet_aton("192.168.38.149", &local_addr.ip);
    local_addr.port = 8888;

New board: STM32VLDISCOVERY

Port the kernel and the pin and uart drivers to the STM32VLDISCOVERY board.

The port has already been started, but is far from complete.

is necessary with FSTR in esp12e board

I found esp 12e has defined FSTR to a static char
simba library use many FSTR string, it cost about 10k+ mem
if i change FSTR to empty, the board is also work
so i don't understand why use FSTR

can i ask something about simba elf .text section/segment

in arduino, string are save in .data section/segment
and i use pio run can show how many mem i used
but simba i guess some string are saved in .text section/segment
my question is :

how to gen the link script (ld) file
why simba string is saved in .text section/segment

it just a consult

Preemptive scheduler

Implement a preemptive scheduler to meet hard real time requirements.

Currently a cooperative scheduler is implemented, and it works very well in most cases. Hard real time requirements can be implemented in interrupt context or with interrupts disabled.

ESP8266 AP Mode

Would love to see support for AP mode in ESP8266.

We use AP mode as a captive configuration portal a bunch: i.e., if it can't find the right SSID to connect to, it'll just create an AP. Best practice is of course to periodically scan for the SSID again.

Anyway, I may be volunteering to develop this, but I'm swamped for a few weeks.

Add ESP8266 port

Run Simba in an Espressif FreeRTOS task

Create a task in user_init() and call sys_start() in the task to make it the main simba thread. Call the espressif schedule function so it can schedule it's tasks.

Use a binary semaphore to make FreeRTOS schedule the Simba thread from interrupts. This Simba idle thread will continiously wait for this semaphore to be given by an interrupt handler.

Idle thread and interrupt handling

Simba theread x starts a job towards the hardware.
Simba thread x is suspended.
Simba idle thread is scheduled and will wait for the binary semaphore.
The FreeRTOS Simba thread is swapped out.
The hardware job is completed and the interrupt handler resumes Simba thread x and gives the semaphore.
The FreeRTOS Simba thread is scheduled.
Simba idle thread is scheduled.
Simba thread x is scheduled.

ToDo

Write a thread context switch function.

ESP32: sockets

Make sockets work on ESP32. ESP-IDF uses newer version of LwIP and potentially other architectural differences to ESP8266.

ADC conversion from ISR

One sample is enough.

Use CMSIS?

Would it simlipy ARM porting if CMSIS is used?

webserver with large http data is not work

I setup a http server with esp12e, listener give stack 2048, http_connection give stack 8192.
if http response a large http data, like 5KB html page.
then the client can't open the page normal.

is that because socket_write size bigger then TCP_SND_BUF ?

SPIFFS data lost on esp12e after reset or reboot

Thank you for this great project of simba !

I use test code (locate on 'tst/filesystems/spiffs/' ) to verify this issue.

I change

BTASSERT(spiffs_format(&fs) == 0);

if ( spiffs_mount(&fs, &config, workspace, fdworkspace, sizeof(fdworkspace), cache, sizeof(cache), NULL) == SPIFFS_ERR_NOT_A_FS) {
std_printf("Formatting file system\n");
BTASSERT(spiffs_format(&fs) == 0);
}

in `test_format(struct harness_t *harness_p)' function, and I get this result after reset the ESP.

enter: test_format
Formatting file system
exit: test_format: PASSED

Does SPIFFS need to format file system every time on boot under ESP12E?

HTTP server in one thread

The HTTP server currently has one listener thread and on or more client threads. This is memory consuming and it should be considered to only have one thread that both listens for connections and acts on requests. It's unlikely that more than one client will be active at a time in small systems.

ESP: ADC module.

Implement the ADC module for the ESP.

ESP32 port

The ESP32 is the successor to the ESP8266. It is a dual core MCU with lots of RAM and ROM. The SDK runs on FreeRTOS and there are an Arduino core and IoT framework already being developed by Espressif and the ESP community.

https://github.com/espressif/esp-idf
https://github.com/espressif/arduino-esp32

Take the same approach as for ESP8266; run Simba in an FreeRTOS thread. It's the only implementation that can be accomplished in a reasonable amount of time.

Adafruit ESP32 development board (out of stock):

https://www.adafruit.com/products/3269

Steps in porting Simba to the ESP32.

Copy Espressif SDK header files and libraries to 3pp/.
Add ESP32 to mcus/ and boards/.
Implement main() and compile, upload and run. Build system changes will be required.
Run Simba in a FreeRTOS thread.
Adapt the WiFi and socket modules. Is hopefully similar to ESP8266.
Port the pin driver.
First step of the port complete!

How to use static ip address on ESP12e?

I use 'network_interface_set_ip_address()' function to setting ip address for WIFI interface, after this action, I can see the ip address use 'inet/network_interface/list' command in shell, but the network is unreachable.

btw, howto config netmask & gateway address?

platformio 3.0.1 says: simba framework doesn't support testing feature

cd project
mkdir test
pio test

how can i do with testing feature?
