Re: Adding I2C memory address to write.

Hi, i2cMasterTransmitTimeout () is the function you need, however the send buffer is monolithic, you cannot split it. The transfer is done using DMA and it is not possible to have non-contiguous buffers. http://chibios.sourceforge.net/docs3/hal/group___i2_c.html#ga78fa5ef397d9742603a246ac4f4f4132 Gi...

Re: Help asked -- PAL-GPIO PWM and Interrupts

Hi,

You should look into the ICU driver, it measures a PWM signal using a timer returning period and duty cycle.

There are several PWM-ICU demos under ./testhal/stm32.

Moving this topic in the correct forum: STM32 support.

Re: Support for RCC_DKCFGR.TIMPRE in newer STM32

Hi,

If you have time add a conditional to hal_lld.h but we need to consider all F4s do the condition should be on the "exceptions".

Re: Binary Semaphore documentation Topic is solved

Hi,

I uploaded new documents, changing terminology would take longer, I decided to use different terms because counter and binary semaphores have different use cases.

Re: [INFO] Enhanced documentation

Hi, Currently there is one document "builder" for the STM32F3xx, it merges HAL and the F3 LLDs, it could be copy/pasted it to make builders for all other platforms, tags are already in place. It is not possible to make a single document with all HALs because a limitation of Doxygen, it can...

Hi,

I split the post from the topic and copied in "Small Change Requests", this way it is not lost in the noise.

Re: one-wire on UART

Hi,

Changing speed is done using sdStart() again (without calling sdStop()), note that if you call it again the execution time is much smaller because just the UART is reinitialized.

Re: one-wire on UART

Hi,

This forum is not for support, you should post in the STM32 section.

Make sure your output pin is assigned to UART, by default pins are GPIO, see your board.h.
