I included the Arduino.h but it didn't solve the problem.

Code: Select all

debug : 'AVREF' was not declared in this scope

It doesn't work in my source.
It doesn't know what the AVREF variable is.

Thanks for your interest in my question.

Is it correct to refer to the Internal_channels.ino source?

hello, I want to read the reference voltage value of the STM32F103C8T6 now, but I can't figure out how. In the case of Arduino UNO, I know that the reference voltage can be read using the code below. float getRefVolt() { // Read 1.1V reference against AVcc // set the reference to Vcc and the measure...

I solved the problem.
The cause was a circuit configuration problem.

Thank you.

Currently, I am writing a code that operates the interrupt function when a falling edge occurs by connecting 3 buttons to the STM32duino by pull-up. Interrupt registration looks like this: attachInterrupt(digitalPinToInterrupt(PA0), button_ISR1, FALLING); attachInterrupt(digitalPinToInterrupt(PA1), ...
