I use CLion with PlatformIO Core CLI.
I upload simple Blink sketch by using target generated for CLion and got Constantly blinking TX LED. It doesn’t happen if I upload via Arduino IDE
Could somebody help me understand:
- Why TX is blinking
- What does it mean
My ini file
[env:uno]
platform = atmelavr
board = uno
framework = arduino
sketch code
#include <Arduino.h>
void setup() {
Serial.begin(9600);
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
Serial.println(“hello”);
}
