The match interrupt on LPTIMx->CCRx is triggered when LPTIMx->CNT > LPTIM->CCRx - not on equal (=) as one might expect

On the STM32U5xx, ST decided to keep this interpretation of "match". It is present on other chips as well, see https://community.st.com/s/question/0D53W000004J0srSAC/stm32l0-lptim-generating-random-compare-match-interrupt-when-changing-compare-match-...

Dear Team STM32F437IIH6TR about this part,could you help me to provide the ECCN/CCATS FILE? We bought a batch of the goods, but the customs asked us to provide ECCN or CCATS documents before we could enter

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.
