stm32f4xx missing HAL_TIM_DMABurst_MultiWriteStart

[Qasdd.1]

Hi guys!

I need to Burst write multiple values using DMA.

The processor that I'm using is stm32F407.

I found than the solution for this task is HAL_TIM_DMABurst_MultiWriteStart function, but it is missing in the HAL library.

https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_hal_tim.c

Therefore it presents in versions for another processors:

https://github.com/STMicroelectronics/STM32CubeF2/blob/master/Drivers/STM32F2xx_HAL_Driver/Src/stm32f2xx_hal_tim.c

https://github.com/STMicroelectronics/STM32CubeG4/blob/master/Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_tim.c

Is that a stm32F4xx hardware limitation? And is there a way to solve the issue? Thanks!

Hello @Qasdd.1​ and welcome to the STM32 Community :smiling_face_with_smiling_eyes:

I confirm your feedback, and our development team is aware of this missing.

The HAL_TIM_DMABurst_MultiWriteStart function is now implemented internally and will be added as soon as possible in the coming release.

So, keep an eye out for the coming update.

Thanks for your contribution and pointing out this issue.
