Anyone that knows the details? Seems backwards.CubeMx generates an init-fuction for CAN which eventually calls HAL_CAN_Init(). The very first part of this function is to exit sleep-mode. As per documentation this means "syncing" - waiting for 11 idle...

I have enabled interrupt for BOFF, EPVF and EWGF.When e.g. sending with error the very fist time TEC becomes = 1, all flags remain 0. However I get an interrupt any way - every time I get a send error. Eventually i get flags set as REC/TEC gets large...

Using a STM32F413 and ADC HAL drivers.After a successfully completed single conversion initiated by HAL_ADC_Start_DMA() one apparently needs to call HAL_ADC_Stop_DMA() in order for next HAL_ADC_Start_DMA() to actually start a new transfer. There are ...

I have had a problem getting DMA TX for USART1 to work, no errors, stream gets enabled nut nothing is transferred, stream never complets. I am using LL driver for USART1.I finally found the problem is that generated usart.c code inits DMA without ena...

I got into strage problems too and spoted this bug. A fix is needed.However I notice this implementation is also very very slow as it scans sectors over and over again, especially transfer page for all my 2000 addresses.

By testing I now how what happens after a BOF + HAL_CAN_Stop() and HAL_CAN_Start(). I write this in case someone else have same problem and/or if ST can take this input and update the reference manual.I have state where BOF is active. I have here ca...

Hmm, after a short break, I suddenly realize that the HAL_CAN_IRQHandler() services ALL different CAN interrupts, generated by CubeMX. Hence a Tx complete IRQ will also find ERROR interrupt enabled and check the flags, mark this as "errorcode" and at...

So same observation as me on F413. Would be nice if HAL IRQ handler could clear DMA flag for this use-case. I added clearing of DMA flag in the ConvCpltCallback() function and then it workt just fine for me. Now however I moved on and use a timer to ...

Initial HAL_CAN_Init() exits sleep mode using what configuration such as bitrate?

Using STM32F413 bxCAN peripheral. Using MX HAL. From RM0430 I think I understand that the ERROR interrupts (Bus-off, Passive and warning) is generated when these flags are set. But it seems like interrupts happens more often than so.

Is there a HAL_ADC_Stop_DMA() alternative to be able to start second transfer using HAL_ADC_Start_DMA() for single conversion?

CubeMX USART1 with DMA, LL driver inits DMA streams before enabling DMA CLK
