Story

Once you have used GDB Debugging it can be frustrating to keep having to grab your project and bring it back to your PC to debug, which isn't always suitable if trying to debug a system in action.

Using the firmware built by Valmantas Palikša you can quickly and easily turn an ESP8266 into a Black Magic Probe, to allow GDB Debugging over a WiFi Connection of a variety of popular boards!

Detailed Guide

We have provided full instructions on our website, with a pre-compiled binary, along with details on building the firmware from scratch.

Code

Example Sketch

int a = 0;


void setup() {
	Serial.begin(115200);
	a += 1;
	pinMode(LED_BUILTIN, OUTPUT);
}


void loop() { 
	function1();
	delay(1000);
	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
}


void function1() {
	a += 2;
	int localVariable = 1;
	byte aNotherLocalVariable = 2;
}
