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.
Low Level SPI transaction on STM32F439z
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...
Resolved! lwıp +ethernet on cubemx for stm32h743zi
I use stm32h743zi microcontroller and nucleo board.When I wanted to use ethernet communication on cubemx,LWIP is not enable.
STM32F103 boot loader question
Occasionally I get a crash - I think when stack meets heap in certain circumstances but I'm still working on that and it's not the issue I'm asking about.The problem is that when the processor crashes I use the boot loader to reload another code buil...
in STM32F373 SDADC example for RTD measurement and I am getting huge noise in raw ADC and RTD temperature variation after configuring other peripherals like TSC and SPI for LCD.
I have used SDADC RTD temperature measurement example from \STM32Cube\Repository\STM32Cube_FW_F3_V1.10.0\Projects\STM32373C_EVAL\Examples\SDADC\SDADC_TempMeasurementwith the same micro STM32F373 and I am getting huge noise in raw ADC and RTD temperat...
how i can recover the state of HAL_Init () with stm32f4
