Inkplate 2 upload fails with Hard resetting via RTS pin error

TECHNICAL SUPPORT Inkplate

Customer:

I just received an Inkplate 2 unit. When I try to upload code to it, I systematically get “Hard resetting via RTS pin…” errors. I’ve followed the setup instructions, installed the drivers and IDE, and verified my configuration appears correct, but I cannot upload anything to the device. Even the boilerplate examples fail. Is the unit defective?

Soldered Support:

The “Hard resetting via RTS pin” message actually indicates that code upload was successful.

Try this basic code for Inkplate 2:

#include "Inkplate.h"

Inkplate inkplate;

void setup() {
 inkplate.begin();
 inkplate.setTextSize(2);
 inkplate.setTextColor(1);
 inkplate.setCursor(20, 20);
 inkplate.print("Hello world!");
 inkplate.display();
}

void loop() {
}

This should refresh the display on Inkplate 2. If the display still doesn’t refresh, try reconnecting the flat cable that connects the e-paper to the board:

  1. Disconnect Inkplate 2 completely.
  2. Dethatch the flat cable holder by gently pulling on the catch/release mechanism on both sides, one at a time, in the noted direction.
  3. Take the flat cable out, keeping in mind to bend it as little as possible.
  4. Connect it back together and secure with the mechanism. Make sure the connection is solid.
  5. Try uploading the Black White Red example.

The example should change the screen.
