ChibiOS Free Embedded RTOS

Thank you for quick answer Giovanni ! I used STM32F4 Discovery board configuration, the OTG pins for STM32f407 (STM32F4 Discovery board) and for STM32f405 are the same, I checked them in Manual. What does STM32F407xx defined constant in board.h? I've tried Latest build of ChibiOS and it does the sam...

I have assembled board with stm32f405 microcontroller and external crystal 8 Mhz. It uses ChibiOS 3.0.2. I wanted to test if USB interface works and ran demo from ChibiOS repository for STM32F4-Discovery board called STM32F4xx-USB_CDC. I can see that code runs from debugger, can even switch led but ...

I started from learning genosensor version but found it too complicated for simple I2C Slave applications so i made my own. I just extended existing I2Cv1 LLD driver, and simplified I2C Slave interface. I even used DMA which was preconfigured in "i2cStart" function. For most I2C Slave appl...

Hello! I'm working on project where I2C Slave functionality is required. As I found in this forum and in documentation there is no support for I2C Slave mode so i had to implement it by myself. Im working with STM32F446RE microcontroller, but I think my API is abstract enough to be ported on other m...

I cant use Chibistudio, Im on mac, thanks anyway for provided code, i Implemented my own driver and merged it with I2Cv1 in ChibiOS 3.0
and i think Github repository is up to date (https://github.com/ChibiOS/ChibiOS)

Still have Errors, looks like you define that function with 2 arguments and miss second argument when use it... , yes i use latest Eclipse Neon 4.6.0 and Chibios 3.0 from Github repository make -j1 all Compiling hal_i2c_lld.c ../../ChibiOS/os/hal/ports/STM32/LLD/I2Cv1/hal_i2c_lld.c: In function 'i2c...

In chibios all hal drivers have "hal_" prefix i just replaced content and including file names but I have several errors make -j1 all Compiling hal_i2c_lld.c ../../ChibiOS/os/hal/ports/STM32/LLD/I2Cv1/hal_i2c_lld.c: In function 'i2c_lld_serve_event_interrupt': ../../ChibiOS/os/hal/ports/ST...

Thank you !
I'm using ChibiOS v3.0 and don't know if it will work there, will try to replace I2Cv1 driver...

I use STM32F446RE and ChibiOS v 3.0.

I figured out that it use I2CDv1 LLD driver... looks like it is different from the version of your I2CDv1, I tried to port your code but stuck on i2c_lld_master_transmit_timeout, looks like it works differently in v 3.0

Thank you for quick replay! In code provided by you on page 3 of this post you use function i2cSlaveAwaitEvent which i think is implemented in "i2c_event.h" file because i didn't found it anywhere else, I guess this function just check SR1 and SR2 register for any status changes but still ...
