I have been able to setup the Arduino IDE using board manager and upload the modified blink example below, such that GPIO 0, 1 and 2 should blink:
void setup() {
pinMode(2, OUTPUT); // Initialize the pins as an output
pinMode(1, OUTPUT);
pinMode(0, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(2, LOW); // Turn the LEDs on (Note that LOW is the voltage level
digitalWrite(1, LOW);
digitalWrite(0, LOW);
// but actually the LEDs are on; this is because
// it is active low on the ESP-01)
delay(1000); // Wait for a second
digitalWrite(2, HIGH); // Turn the LEDs off by making the voltage HIGH
digitalWrite(1, HIGH);
digitalWrite(0, HIGH);
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
}
With that sketch, whatever pin is connected to the built in led should blink.
While I compile and upload, I get the following log, showing a successful upload and compile:

so there shouldn't be any problem....
however, I get no blinks
I use the following USB adapter, and you can see it is modded with buttons from GPIO0 and RST to GND so I can flash it
I have tried resetting, plugging it in a different power supply without any luck.
Have any of you experienced something similar? Or maybe have any ideas I can try to make it work?
