Bring up the display on a matching ITead carrier

Required

With power disconnected, seat the connector on the matching carrier. Check the GND/DB0 end against the bottom-view drawing. Keep the SD slot empty for the first display test.

Bench checks

  • Use the UTFT profile for ITDB02-3.2WD and the host pin assignments for the carrier. Run a color-fill example.
  • If the backlight turns on and no pixels change, verify display reset and the write strobe. Check both eight-bit halves of the bus if colors are incorrect.
