I am working for stm32h753zi and i am trying to measure ADC reference voltage. But i got 5.74466228 instead of 3.3v.Please any one give me the guidance. I have attached steps i followed, Thank you.

I am using the code :int read_adc_data(ADC_HandleTypeDef *ptr_hadc, uint32_t channelx){  uint16_t vrefint_cal;  float adc_read_value = 0.0, adc_reference_voltage = 0.0;  ADC_ChannelConfTypeDef sConfig;  sConfig.Channel    = ADC_CHANNEL_VREFINT;      ...

The internal temperature measured by the ADC is different in debug and not debug mode. When I am debugging, the temperature value measured is correct (about 23°C). Without the j-link debugger, the temperature measured is incorrect (about 18 °C)

I send the temperature value on a serial interface.In the live watch of the IAR tool, I can see the same correct value than the one sent on the serial interface.The problem occurs after a power-down/power-up of my board, like if something is not init...

STM32F207+ADS127L01 SPI

Hi there i cant get a real data from ADS1227L01. In debug mode i see the value 0xFFFFFF.Q1: If anyone used ADS127L01 can they send me librarys for comparison ? Q2: Im using 3.75MBits/s Baund Rate is it enough for 24 bit data?

So I'm having this weird bug I can't seem to figure out.I'm trying to connect two stm32f4 discovery boards through SPI.The master is sending out a SS signal I want to use to synchronize with the slave.However for some reason before I send out a messa...
