Hi Folks,All of the examples I see online show that in the CubeIDE there is a selection to enter the rank of the A/D inputs. I can't find that in my version which I believe is the latest version. Can someone point me to how I should accomplish this?I...

Hi Folks,This has been driving me crazy. I'm using a Nucleo-L031 board and it's connected to a I2C TCA9548A 1:8 multiplexer. I am trying to read 4 sensors connected to the mux chip. I have 4.7K pullups installed at the Nucleo's I2C pins. The sensor b...

Hi Folks,I have the latest version of the IDE (1.16.1) but now the search feature won't work. It will only return an error:When I try to search for "HAL_StatusTypeDef I2C_WaitOnSTOPFlagUntilTimeout" I get the following set of errors:Text SearchAn int...

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...

I have highlighted the missing STOP bit. Channel 0 is the SCK line connected to the Nucleo board. Channel 1 is the SDA line connected to the Nucleo board. The yellow output is connected to the SDA line of the 1:8 mux chip (TCA9548A).From the image i...

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...
