I just got my STM32L053 Nucleo64, and i'm stucked when i load on the flash memory with keil (µvision5). The error "internal command error" occured.You can take a look at the error details.This is my keil setup : here and here.And this is my STM32Cube...

I'm using 4 ADC channels and sending the data to a DMA buffer. The data from the different channels are interfering with each other and i'm not sure why. The goal is to read from PA0, PA1, PA4, and PA5 at the same time. so i may going about it wrong.

my data for this looks like the following without giving inputPA0 PA1 PA4 PA50 250 216 190I expect this PA0 PA1 PA4 PA50 0 0 0and when i start giving channel PA0 data wit...

I am currently running into a problem using an STM32F446 microncontrollers UART interface that i cannot explain and require help.The system we are looking at is meant to do measurements.Each measurement cycle is triggered by an external Host.The Host...

Using a timer to trigger DMA to read ADC.

Hello,I'm using the STM32F779.I have a timer configured to to trigger an ADC (single channel) using the timers TRGO.This is working great but I'd like to have a DMA handle the transfer.The timer triggers every 2ms and I'm running the timer for severa...
