Hi Folks,I'm having an issue with just reading and writing new values to the RTC. I'm using a custom board that contains a 32.786Khz crystal and in CubeIDE the LSE is setup properly. I also have a battery connected to Vbatt,I'm using the following to...

Hi Folks,I'm having a problem with connecting my ST-Link/v2 to my new board with a STM32H7ARIT micro on it.I have had no problem connecting the ST-Link to another board with the STM32F103RBT6 micro on it. I have the Debugger configuration in the STM3...

Hi @SofLit,I need to develop a unique serial number for one of our products that will go into production soon. I'd rather use the UID that is built into the STM32H7A3 chip but I have some questions.I understand that it is a 96bit value that I can rea...

Hi Folks,I'd like to find an example of accessing a USB drive using the STM32CubeIDE. I'm currently using the Nucleo-H7A3Zi-Q board.I believe I have setup the hardware correctly using the device configuration tool but I can't seem to find a simple or...

Hi Folks,Is there a simple description on how to read and write to flash using HAL for the STM32H7A3 chip somewhere?I'm looking at the example in the STM32Cube_FW_H7_V1.11.1 FLASH_erase_program.My application needs to store ten 8-bit values so I'm no...

I got it working by only using half of what you originally suggested. This is what works (so far): /* USER CODE BEGIN Check_RTC_BKUP */ if((RCC->BDCR & 0x8000) == 0) // rtc enabled ? <-- this 2 lines { /* USER CODE END Check_RTC_BKUP */ /...

AScha.3,Here's my function with your two lines included: void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ if((RCC->BDCR & 0x8000) == 0) // rtc enabled ? <-- this 2 lines { /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}...

I'm not quite following what you are suggesting. Here is the STM32CubeIDE generated RTC.C code:/* RTC init function */ void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RT...

CAlbe.2,Did you ever figure out what was causing the problem? I have a somewhat similar issue with our Nucleo-H7A3ZI-Q board and a 7" LCD display that is using the RA8875 controller chip. We're using a 4 wire SPI interface. Sometimes the screen comes...

SofLit,I did open up a new thread and I tagged you (it's this thread). RM0433 is the manual for STM32H742 and '43 chips. We're using the STM32H7A3 chip. Both of the manuals (RM4033 and RM4055) show pretty much the same information. Neither one adds a...
