I am expecting there must be a similar callback function like HAL_UART_TxCpltCallback, HAL_UART_TxHalfCpltCallback in case of using UARTs when using DMA-burst for generating arbitrary waveforms with PWM in order to be able to update the memory buffer...

yep, that what was my conclusion, too. But it's called with every pulse and not when DMA transfer is complete or half complete. Or maybe I misinterpreted that.

No, unfortunately your suggestions does not work for me. The callback doesn't get called. Not sure what I am doing wrong here.

Thank you. I have briefly tried this already, but I'll try again. I was asuming the TIM_PWM code is consuming the DMA callbacks.
