Re: STM32F103C8T6 Reference Voltage READ
Following your advice, I was able to read the datasheet and read the ADC1_IN17(Vrefint) value.
With Vrefint and the following formula, I was able to get a value of 3.27~3.28V.
float VRef = (1.20 / vrefint) * 4096.0;
I measured the voltage on the board and it came out 3.314V. Is this an ...
