ChibiOS Free Embedded RTOS

Yes, serial driver works good but there are some compilation problems with uart - missing brackets. There's patch.

Hi,
Giovanni, thanks for tip about CSELR register. I modified dma driver for L0 and add simple workaroud. I choose some the most important peripherials (in my opinion) and connect them to free channels. Currently Chibios UART testhal works perfectly with nucleo board Just connect, program and open ...

Ok, but it is possible to run example apps without big changes in DMA support. Only for tests and initially support new platform

Hi,
Do you think about DMA_CSELR register?
F09x also has this register.

Hi,

The most important thing to do now is to run UART to communicate with µC. DMA with UART seems to work good, but doesn't send characters.
The second problem is how to implement and manage low power peripherials. Currently I only see it on schemes and I must to read more in reference manual. It ...

Few days ago I purchased nucleo with STM32L053. This mcu is other than well knowns mcus like L1 or F0 (eg. GPIO bus compared to L152). I also saw that chibios not support this mcu and I need to run chibios on this board (yap, I want to test my MSc project on cortex M0+). Today I spend few hours to ...

It really works! Thanks Giovanni!

I know that few weeks passed from last reply but... I also tried to find mcu frequency function and couldn't find it.
If you still need STM32F4 core frequency in macro you can use this define:

#define STM32_CORE_FREQUENCY (((STM32_HSECLK/STM32_PLLM_VALUE)*STM32_PLLN_VALUE)/STM32_PLLP_VALUE)

STM32 ...

Ok, so maybe first: I work with Wojtek (wbober).
We tested our old I2C IRQ code and sometimes we could see errors.
We've got i2c temperature sensor. It looked like STM could read values from sensor, but after few hours all values were read the same. I read carefully whole datasheet and catch some ...

Today We improved code. Last code has bug and i2c stucks sometimes. Current code works as it should.
