Soldered Support:

This could be a loose connection of the flat cable. Try carefully reconnecting it:

  1. Turn off Inkplate 10 completely
  2. Turn the device around and locate the flat cable connector
  3. Carefully pull the tabs on the connector up
  4. Remove the flat cable and then re-insert it
  5. Pull the tabs down and make sure the connection is secure
  6. Try the sketch again

Be careful not to bend the cable as it’s delicate. Let me know if this works.

Customer:

The Inkplate arrived in working condition but the display issue persists. I’m willing to replace the e-paper to fix it. What should I do?

Soldered Support:

These ePaper models are compatible with Inkplate 10:

ED097OC1
ED097OC4
ED097TC1
ED097TC2

Replacement should be straightforward - just connect via flat cable.

After you connect the new display, upload the Inkplate10_Factory_Programming_VCOM.ino sketch and set the VCOM and waveform for best display results (this sets the contrast and accuracy of the ePaper).

In this sketch:

  1. Remove the testPeripheral(); function call (line 124) to just set the VCOM and waveform
  2. Change the EEPROM offset (line 51) to some other number
  3. Upload the sketch and open Serial monitor at 115200
