ChibiOS Free Embedded RTOS

SOLUTION!

I accidentally came over how to fix it, after trying to add more functions

Solution is after calling dmaStreamDisable(), you must always setup the mode again with dmaStreamSetMode().

Hi! I've been trying to setup a simple example on controlling a LED (WS2812) on the STM32C071RB chip with PWM + DMA. Most things work! However, it seems that the callback dma_callback is never called. Any tips on what to look for to make it work? Here is the main.c file for the example code: #includ...

Alright, I just double checked the numbers, and it seems to be alright. But, I just discovered something I didn't think would have affected the example code. If I commented out the following lines pwmEnablePeriodicNotification(APP_PWM_DRIVER); pwmEnableChannelNotification(APP_PWM_DRIVER, APP_PWM_LIN...

Hi! I've been experimenting this week with the PWM driver for both a Nucleo-C071RB board and a Nucleo-F401RE board. I seem not to be able to reach periods of 1.25us (trying to build a simple ws2812 example). ChibiOS: stable_21.11.x branch Boards: NUCLEO-C071RB (48MHz clock) and NUCLEO-F401RE (84MHz ...

Sounds like a good idea, it could increase development activity by open source developers and generate a bigger community for ChibiOS.

Hmm, alright! I'm gonna have to get some progress working on my project. However, I will mark this as something I can investigate in September. To be noted, I compared quickly TIM2 for the STM32C0xx and STM32G0x1 reference manuals, and saw that in os/common/ext/ST/STM32C0xx/stm32c071xx.h, these thin...

Alright! I made a new post in Bug Reports: viewtopic.php?f=35&t=6590

Hi! Posting this as noted from post https://forum.chibios.org/viewtopic.php?f=16&p=43440#p43440 Update of STM32C0xx port files, implementing missing code for USB (and CRC) related code, as well a change in the mcuconf.h file of the RT-STM32C071RB-NUCLEO64 demo (STM32_USB_USB1_LP_IRQ_PRIORITY). T...

Pointing this discussion to viewtopic.php?f=38&t=6587 (TLDR; Change system timer with config files)

I got it fixed by adding: os/hal/ports/STM32/STM32C0xx/stm32_isr.h /* * USB units. */ #define STM32_USB1_HP_HANDLER Vector60 #define STM32_USB1_LP_HANDLER Vector60 #define STM32_USB1_HP_NUMBER 8 #define STM32_USB1_LP_NUMBER 8 os/hal/ports/STM32/STM32C0xx/stm32_rcc.h /** * @name USB peripheral specif...
