Connect the DT018ATFT in 3-wire SPI mode

Required

Use the manufacturer’s 3.3 V 3-wire fixture. Connect the two LED cathodes through separate 130 Ω resistors for a quick illumination test. Use a constant-current driver for normal backlight operation.

R2 130 Ω between LED return 2 and GroundLED return 2R2 130 ΩGround

Bench checks

  • Measure 3.3 V at VCC and VDDIO before releasing reset. Confirm the mode straps remain low.
  • Check that the first bit selects command or data and is followed by eight bits. Run the DT018ATFT initialization and verify a 128 × 160 test image.

Models and documents

The physical map covers the 45-contact DT018ATFT flex cable. On this panel, the manufacturer hardwires the controller’s SPI4 selection, so the documented serial option uses 3-wire framing.
