STM32 MCUs Products

In theory, you can use all 26 bit of the STM32U MDF in the CIC stage. In practice, I recommend to stay < 25 bit to avoid artifacts and saturation.

Interruption, but corresponding interrupt flag is not set?

Dear community,I am having a strange problem with the STM32L431.The ADC is set up for use with both the DMA and interruption. This is to de-interleave the adc results from 2 different channels, since there was problem with interleaved ADC results whe...

Is there a way to tell whether ADC is busy? (STM32F303ve)

I am trying to reconfigure DMA without losing samples and without stopping the ADC, which is triggered using timer (relatively rarely), so my plan was to look whether both the ADC and DMA are idle and quickly reconfigure DMA before ADC even starts to...

Correct Timer Configuration for Capturing Edge Times In Order to Calculate Pulse Width

Hi, I am using an STM32F429 to calculate the pulse times from an an IR receiver. The IR receiver outputs a signal that follows the NEC Protocol, which is defined here: https://techdocs.altium.com/display/FPGA/NEC+Infrared+Transmission+ProtocolThe pro...

Are there any "getting started" guide availabele for b-l475e-iot01a

I am new to BLE development and hence i am looking for a developers guide for using BLE on b-l475e-iot01a  discovery board.-Thanks in advance.

USART Receive to Idle DMA callbacks

I got this working, then it stopped working.I finally figured out after about 3 hours what is wrong.Situation. I am making a "Serial tap" for debugging. The STM32F411CE on the Black Pill board. 2xUSARTs Rx only and the CDC Virtual COM port device ...

How can I transmit a UART message using a SMT32G474 B-G474E-DPOW1

I am not new to working with STM32 MCUs but this is a one-of-one.I have checked the baud rate to 115200 with 8E1, the serial com port driver is showing up on my computer and when I measure the USART-TX pin using an oscilloscope it is showing a signal...
