avrdude.exe: stk500_recv(): programmer is not responding

Hi

Glad to hear you have solved your Nano problem.

The above error message can occur when swapping targets. Whilst Flowcode allows you to do this very easily, negating the need to start again from scratch, you need to be aware that not all targets have the exact same pin / designations.

Whilst it is extremely easy to move between for example, 8-bit PICs, as their port / pin designations are very similar, it isn't the case when going from one manufacturer to another.

Port A Bit 2 may be available to use on your Nano but Flowcode is telling you that this Port and / or Bit is not available for use in the ESP.

Simply look at your ESP datasheet and choose an available Port / Bit and you should be good to go.

Hope this helps.

Regards

Hi

Below is a simple chart I created to illustrate. In it I have a LED connected to Port D0 of a Nano.

I then changed the target to an ESP. However as an ESP doesn't have a Port D it is left unconnected. All I need to do is simply assign the LED to any of the available ports the ESP does have

Much quicker than starting again

Ah, ok, got it now... so that information message was just something in case I migrate between Arduino and ESP32. It's more like a feature and not a bug.

Yep

Pretty much it
