Re: WEMOS ESP8266 D1 (Arduino sized) board - problems!

So back to fundamentals:
When I load the BLINK program, which I've had to change to use the LED_BUILTIN constant to get a blinking LED (which refers to pin 2) the actual pin on the D1 board is TX1/D9.
Underneath the board is printed GPIO2 for that pin.
So I'll write a quick sketch to set each pin HIGH and use my multimeter to check that the GPIO number printed under the board refers to the digitalWrite(PIN...) that I'm using.
Then I'll see about getting my original program (that caused the RST) to run.
