Resolved! Circular DMA on ADC runs once and stops

I'm using an STM32H563. Setup to get ADC captures into a buffer using DMA in circular mode.I have TIM1 triggering an ADC1 conversion of two channels. And a buffer with 16 readings using DMA. The GPDMA is set in Standard Request Mode and Circular enab...

Resolved! STM32h725 Slave PSSI bad length

Hello,I'm trying to use the PSSI bus in slave mode to transmit data from a small FPGA. After some time chasing a weird bug (I'm losing 8 32bit words at the end of packet) I decided to use a logic analyzer on the bus and it showed a weird behavior fro...

Resolved! STM32F401 Datasheet Error? Vih

So table 54 Vih for 5V tolerant pins is 0.7Vdd. For Vdd 3.3V this is 2.31V.I'm having input capture trigger on signals that only reach 1.8V with 100% consistency on 4 pins.Most stm32f4 the Vih for the same pins is 0.45Vdd + 0.3V, which would be 1.65V...

Resolved! STM32F44: UART Noise/Frame error with externel CPU clock

HiI have a self designed board (STM32F44 MCU) with an UART communication. It works well as long as I configure it to use the internal clock. As soon as I switch to the external clock (oscillator), the UART communication gives a noise and frame error ...
