HAL_SD_GetCardState Unreliable Delay
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...
Resolved! STM32F2 Inverted DAC output on some boards
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...
Output signal is being attenuated after the Biquad filter direct Form 1, why?
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...
Resolved! Can the STM32G4’s DMA multiplexer (DMAMUX) be synchronized to a timer other than LPTIM?
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...
Resolved! GPIO for SPI communication ST example is not set?
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...
STM32 SMBUS - Communication error during block read/write - SDA remains low.
Hi,I'm working on a project with a STM32L475RC and I'm facing problems with the SMBUS.The STM32L475RC is used as a SMBUS/PMBUS Client. As smbus/pmbus stack I use the X-CUBE-SMBUS Expansion Package (AN4502).Now I'm facing problems with block transfers...
Using IDLE Line Detection + DMA on STM32L42x
In my opinion one of the simplest ways to receive an unknown amount of data has been this post which details how to use IDLE line detection to trigger the DMA to call the HAL_UART_RxCpltCallback function. This then reads the data received via UART fr...
I use STM32F030R8T8 programming with CUBE and TrueStudio. I have a problem with the frame error in UART communication on RS485 line. I have implemented the error_callback function to reset the error, but receiving remains blocked.
In a similar question it is recommended to carry out the instructions:void HAL_UART_ErrorCallback (UART_HandleTypeDef * huart){ // I implement this .. but eventually you can decide with different approach // Many macros / proc on this code .. is just...
