Resolved! STM32G431 I2C with HAL gets stuck in the interrupt

I am trying to use a G431 as an I2C device (slave). Unfortunately it can be made to latch up rather easily, getting stuck with an endlessly triggering I2C interrupt. It appears to be a flaw in the HAL code where it doesn't clear the interrupt flags, ...

STM32H7 won't calibrate using STMCubeMX v6.13.0

CubeMX-generated code gets stuck on HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED) using IDE v1.17.0 and FreeRTOS. RTOS is using SystemCoreClock. HAL Tick is using TIM17 with a priority = 14 (Higher than SysTick Timer.)Made AdcTask highest pri...

Resolved! STM32F7: DMA GPIO to memory

Hi, I'm trying to connect a high speed ADC to an STM32F7. I have chained two timers to generate the necessary convert and read pulses to the ADC. Its output is 16 bits that are all connected to the same gpio block. However I would also like to setup ...

Multi-channel audio streams

HiI'm planning to make a digital mixer that takes 4 analog audio input channels (2x stereo), processes them with digital effects, in 24 bits, and outputs 4 analog audio channels. I’m trying to figure out which chips may be compatible for my project. ...

Timer update event delay

I am using timer15 to generate TRGO by update event, which is used to trigger DMA to transfer data via spi.From the oscilloscope, I found a delay around 150ns between rising edge of TRGO (PWM output on PA2) and first pulse of SPI sck.I am not sure wh...
