STM32 MCUs Products

STM32F411 specs for ADC are 2.4 MSPS. my waveform generator set at 500 KHz captures 12 values from peak to peak, indicating 6 MSPS. Using DMA, no repeat values to indicate it is re-reading the adc_dr . ???

STM32L0x1, trying to get UART2 interrupts working. UART2 on PA2/3 is selected Tx interrupt is working, Rx is not, intermittent results. Modes: Microprocessor Communication and Asynchronous act the same. Details below.

Intermittent results during a loopback (same processor, Tx to Rx) test. Happens the same on both STM32L041G6 and STM32L051K8U6 processors.STM32CubeIDE (recent version) used to enable Uart2, Interrupt enabled, no DMA, 9600 baud, 8bit, 1 stop, no pari...

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...
