Are there HAL functions to generate DMAMUX events?

[mattscar]

I'm programming an STM32L552, and I've used HAL functions to configure DMAMUX synchronization. There's a field that enables DMAMUX events, but I haven't found any functions that generate DMAMUX events.

According to the documentation, "The DMAMUX may also be used as a DMA request generator from programmable events". How do you program these events? Thanks!

Hello @mattscar​ ,

I advise you to refer to these resources that will help you to how to configure the DMAMUX with example using the DMAMUX request:

• How to use DMAMUX on the STM32 microcontrolles
• AN5224 STM32 DMAMUX: the DMA request router
• UM2659 Description of STM32L5 HAL and low-layer drivers
