Incorrect values by ADC on STM32H750

Hello!A simple setup to run the ADC1 in continuous conversion mode runs as expected, but the measured values are incorrect as inspected via the debugger console. When connecting the ADC1 input pin to GND or 3.3V volts the measured value doesn't chang...

Configuring Idle State for Timers

HiI have successfully managed to configure and implement a TIM4 channel 1 as a PWM channel and connect it to DMA. Upon disabling the DMA after a transmit, the output goes high - this was the default and is desired. However, I've taken this further to...

Resolved! Is there a maximum speed with DMA? (F446RE)

Hi, I am using DMA to generate an arbitrary waveform on PIN PA_8 using TIM1_CH1. My HCLK is at 180MHZ, APB2 timer clock at 180 MHz and APB2 peripheral clocks at 90 MHZ.Even though having this clock, when comparing the oscilloscope and the value of AR...

Resolved! STM32G030K6T6 is not programming!

Hello,I'm working on a small scale project. In my earlier design, I've used the STM32F100x series. Now as the STM introduced a new set of controllers, the STM32G series ( which is less in cost and much higher efficiency than STM32F series), I've migr...
