HAL_SPI_Receive_DMA() is non-blocking; it just sets up and starts a transfer. Is it safe to call it from an interrupt context?If it is (at least possibly or sometimes) safe, does it make a difference whether the SPI port is configured as SPI_MODE_MAS...

I'm trying to do a periodic ADC capture on 2 channels, triggered by TIM5. ADC should output to memory via DMA, with a DMA interrupt upon each completion to read the data from each scan.So far, the DMA interrupts aren't hitting, and the ADC doesn't ev...

In STM32CubeMX, version 6.3.0, using STM32CubeF4 v1.25.2, when a SPI port is set to mode "Receive Only Master", it sets `hspi#.Init.Direction = SPI_DIRECTION_2LINES_RXONLY;` in generated code, as (I think) it should. However, the generated code doesn...

Is there any guidance or examples to follow for implementing the Cortex Debug+ETM Connector (20-pins, 0.05") on an STM32F4 board, with the connector as specified here, such that ETM trace is usable?J-Link/J-Trace User's Guide: Connectors (keil.com)e....

Thanks for your help.On further investigation, I see no sanctioned way with the (non-LL) HAL to enable the channels before starting the PWM output.I'm working around the issue by (ab)using the private function TIM_CCxChannelCmd(). I've replaced TIM_...

> Did you start...1. No, actually - we callHAL_TIM_PWM_Start(&htim5, TIM_CHANNEL_4);Maybe this is the problem, as it doesn't start TIM_CHANNEL_3? How would I start them both at the same time, and produce the same output as this does on CHANNEL_4? (HA...

Changed as specified. Problem persists, i.e. HAL_ADC_ConvCpltCallback() still isn't called.
