Arduino for STM32

OMG I forget about instantiate Serial2, Thanks, it works!

Hi! I try to connecting STM32F103C8T6 with Nextion LCD (NX3224T028_011) using Arduino IDE. while I compiling the code, there is an error says like this

c:/users/asus/appdata/local/arduino15/packages/stmicroelectronics/tools/xpack-arm-none-eabi-gcc/12.2.1-1.2/bin/../lib/gcc/arm-none-eabi/12.2.1 ...

I using core from rogerclarkmelborne before, and I try another core in this link

And after that i found article about HardwareSerial in this link

This is my code

wow thank you it's very helpfull ! I will read all these article first

Hi im from Indonesia
I just want to learn about microcontroller. And at this time I curious about STM32 with arduino IDE. I still learn basic knowledge about STM32 family. Thank you

hi, I'm new to STM32duino. Yesterday I try to access Serial2 in STM32F103C8T6 and fail. I only can access Serial1 in PA9 and PA10. anyone can help? Here is my code

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial2.begin(9600);
Serial3.begin(9600);

}
