Connect TM035PDH03 in 4-wire serial mode

Required

Set IM2:IM0 to 111 before reset. Connect the 3.3 V host and panel supplies to the same regulated rail and ground the unused parallel and RGB inputs.

Bench checks

  • Check the flex orientation, both panel supply voltages, and independent backlight current before sending commands.
  • Observe the active-low reset and compare the first SPI transaction with the module timing diagram. Use the Tianma panel initialization and verify a full-width color test.
