H755 / ADC3 / DMA
Hello,I'm desperate. Just want to concvert some data with the ADC3 with DMA on a H755.No chance! DMA doesn't work, and even a cyclic sample only produces the right values for the first turn. After that, only max. resolution is returned. 12 bit => 0x8...

Block for sending values through the UART
Hello, I am trying to wire STM32F103C8T6 with DS18B20 sensor and I realize that after some actions it stopped to work and no data through the UART sent: Probably it's not big deal, but I have no idea why UART completelly blocked and sending no in...
Resolved! STM32N6 XIP from OctoFlash does not work depending on AXI-clock
Hi everyone! I'm trying to run the STM32N6 (using the STM32N6570-DK discovery kit) in Execute-in-Place mode. I followed the official tutorial for this, and everything works fine. The tutorial uses very low clock speeds for the CPU and AXI, namely 64 ...
Resolved! STM32U5A5VJT6Q VDD11 connection
Hi,STM32U5A5VJT6Q has 2 VDD11 pins. Should these be connected together using an external trace on a PCB? I did look at Nucleo U5A5ZJ-Q schematic but I'm still not sure.Thanks,Adam
