USB performance on STM32H7

Hi All,This is related to performance on USB Host in FS mode. I have built custom board with STM32H743BIT6.Main interfaces on this are - USB FS Host, SD Card (SDeMMC interface used), LTDC, 16Mbyte SDRAM and Ethernet. All the interfaces are up and run...

STM32L4 RTC [LL driver]: Bug in LL_RTC_ALMB_SetDay(), should be RTCx->ALRMBR, not RTC->ALRMBR

The HAL file, stm32l4xx_ll_rtc.h has a bug in LL_RTC_ALMB_SetDay(). It should be using RTCx->ALRMBR instead of RTC->ALRMBR that is in the code.

I've been messing with the LL drivers for SPI and have run into some confusion.I have HCLK set to 100 Mhz and PCLK1 set to 25 Mhz.I set up the bus using the code generated from STM32cubeMX:static void MX_SPI1_Init(void) {   /* USER CODE BEGIN SPI1_...

Migrating FATFS SD Card code (on FreeRTOS) from STM32F7 to STM32H7

As the title says, I am trying to migrate some code that once was running on an STM32F7 over to STM32H7 (nucleo boards). I have had all sorts of learning hurdles switching over to the H7 which most have been resolved. The issues in general were due t...

I work with the TIMER2 in INPUT CAPTURE mode, the interrupt is triggered on rising or falling edge. I want to get both trigger times on both fronts using the conditional statement "if" and the HAL library.
