Arduino for STM32

Confirmed, it works.

Thanks.

Thanks. very much.

now i have to learn how to install from git rather than just download from IDE.

I'm sorry for that.

I'm very new here, and this is my first time work with Arduino_STM32.

I tried to read the issue, but i don't quite understand 'analogRead: don't set ADC common register when ADC doesn't support it.'

does that mean i can't use this ADC3，or is there another we to get the number ...

Version: STM32 Core 1.8.0
Arduino Verison: 1.8.12
UploadMethod: ST_LINK

Chip：STM32F103RCT6

code:
HardwareSerial Uart1(PA10,PA9);
int fold_current;

void setup() {
pinMode(PC3,INPUT_ANALOG);
Uart1.begin(9600);
}

void loop()
{
fold_current = analogRead(PC3);
Uart1.println(fold_current);
delay(100 ...
