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

Re: STM32F103C8T6 Reference Voltage READ
Code: Select all
debug : 'AVREF' was not declared in this scope
It doesn't know what the AVREF variable is.

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

STM32F103C8T6 Reference Voltage READ
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...

Re: STM32F103C8T6 External Interrupt Problem
I solved the problem.
The cause was a circuit configuration problem.
Thank you.

STM32F103C8T6 External Interrupt Problem
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), ...
