DAC TEN and SWTRIG

Hi everyone, I'm experimenting the DAC features with my STM32F303RE and I have a dubt. .RM says: "If the software trigger is selected, the conversion starts once the SWTRIG bit is set".Now, if I only set the DAC_DHRx and the EN bit, the DAC works pro...

uart communication between stm32 and stm32

HelloI want to use two STM32F407 MCUs to enable bidirectional communication via UART communication with each other.I would like to have a two-way communication that turns on and off each other by installing a switch and an LED, respectively. Thanks a...

Hi, I wnat to know about the bad block management in stm32. How did i find these MCU support bad block management?, Please give me the details what are the MCU's contain bad block management. Thank you.

Using a STM32H7 and internal ADC through DFSDM using sinc filter and aliasing protection

Using a STM32H7 and internal ADC through DFSDM using sinc3 filter and would like aliasing protection.The sinc filter has the notch at the new sample frequency. I would prefere to have the notch at half the new sampling frequency to get better aliasin...

PDM_Filter() erroneous 1st 2 PCM-converted data

Hello newbie here.I am trying to learn how to convert PDM data to PCM using PDM1_filter() function, I am using GCC.The first 2 converted PCM data seems to be abnormal as can be seen later.Firstly, instead of directly interfacing to a microphone or an...

stm32 CAN bus: A sends data to B nodes.

I have 2 nodes, A and B, they set filters for both, now A is sending data frame, B can receive the data from A. but A originally can receive data from B, but after around 1-3 mins the receiving data mainly from itself, minorly from B. but if i rese...

I2C timeout not working correctly

I have tried enabling the timeout function in the I2C controller by setting a value in TIMEOUTA and setting TIMOUTEN. I can see the bus working normally on a scope, then when I connect with the debugger ( no reset, no upload ), the halt causes the t...
