FatFs unrealiable under high load on STM32H743

2023-11-10
Hello,I am using a STM32H743 with a W25Q128 external flash memory running FreeRTOS and FatFs. USB is configured for mass storage, to copy files from a computer to the flash memory. The following function is used to list all the files and directories ...

Optimizing FIR Filter Multiply Accumulate

2023-09-26
Hello,I am trying to optimize a function for a basic FIR filter on a STM32H743. This is the function:inline float_t FIRFilter(const float_t* inputBuffer, const float_t* firData, const uint16_t size, const uint16_t currentBufferIndex) { float_t outpu...

STM32H743 SAI DMA noise

2023-09-05
Hello,I took over working code that I have for a DSP project from an STM32F439 to an STM32H743. On the F4 I had the external audio codec connected to the I2S peripheral but switched over to the SAI on the H7. Now I am experiencing excessive noise whe...

NUCLEO-H743ZI2 USB Device not working with standard USB OTG configuration

2023-08-29
I tried to port some code from an STM32F4 development board to an STM32H743 NUCLEO development board. I noticed that the code for the USB Mass Storage Device Class was no longer working. After spending hours of troubleshooting I found out that the "B...
