We are using the STM32H745 dual core MCU in the we are trying read and write the data using DMA. When we are trying to receive the data that controller going to the DMA error call back function ,for this what may be the issue . And also in interrupt ...
Hello,I'm using STM32f411RE with ADC and I would like to know why when the sampling time is less than 84, I don't find by calculation the same expected conversion frequency/time?My calculation is Tconv = (3+12)/210000Hz = 714 ns so a frequency of 1.4...
Hi!I am using STM32F373RCT6 on custom board. I am working from scratch on SDADC.I have configured SDADC1 Channel 6 to read the voltage in polling method but it is not working. I am sending .c files for your reference to check configuration. After ca...
Hello All,I am attempting to utilize the SDMMC port on the STM32F7 to transfer large images from external SDRAM to an attached SD card. I am currently doing this successfully at 5 FPS. I want to speed it up to 10 FPS, but I am having unreliable delay...
Hello,I have 3 boards with STM32F205RBT using 2xDAC and 9xADC. Two boards are working just fine but one board has the second DAC output inverted (write 0 ->3V, write 4094 ->0v). The same program is used, boards are the same. The DAC output is amplifi...
What's going on is that I finally got my low pass digital filter working on the STM32H753ZI using the PMODI2S2 peripheral and I noticed the output signal is extremely low ~340mVpp this is after the biquad filtering. If I take out the low pass filteri...
I’m working with an STM32G474RE chip, and I’m trying to use the synchronization feature of the DMA multiplexer to time when a DMA transfer to SPITX should occur. I’d like to have this timed synchronously to some other timer events.Looking at the docu...
Dear ST Hello,I am using the ST example for SPI communication for getting started with STM32F429i-discovery.This the header of the main file. ****************************************************************************** * @file SPI/SPI_FullDuple...
