Hi All,I have been a little confused about my code and would appreciate some help greatly...I have a basic program where I would like to read the ADC values from a sensor, and transmit them via UART for later signal processing and whatnot.The structu...

Coming back with a little breakthrough - but not sure how ideal this situation is. If I change the DMA for ADC from "circular" to "normal", and put the two in the main while loop, then I manage to read the ADC values and send them via UART. while ...

I just toggle it in the main while loop (RGB LED, and I just toggle the red channel) to see if the program would still function correctly when I read the ADC with my sensor values. while (1) { int del = 500; htim4.Instance->CCR1 = 255; H...

If I run just the HAL_ADC_Start_DMA , then when I press on my pressure sensor - the values are visible in the live expressions - they go from 0 to 2555, which is a value I expect.

I will try that in a second and will let you know how it goes. What I have found out is that if I toggle an LED every 500ms, it works perfectly alone, but then if I uncomment the "HAL_ADC_Start_DMA(&hadc1, value, 2);", the LED gets stuck on always ON...

Doesn't look like there could be any conflict. I will scrutinize the PCB itself more
