Good afternoon. After updating the arduino core, SERIAL and CAN stopped working. platform = ststm32@13 — works platform = ststm32@15 — doesn’t work.
Tried using
Okay. I am using STM32F103RCT6 microcontroller. My code is very large, so I created a simple project where only UART is used. This code compiles without problems, but the UART output is empty. If you change the kernel version in platform.ini platform = ststm32@13 or lower. Then the UART pin works without problems.
main.cpp
#include <Arduino.h>
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial.print(“test”);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.print(“test”);
delay(1000);
}
