Bench checks
- Verify the supply and mode straps before driving the bus. Check the ILI9320 pin descriptions for unused inputs in the selected mode.
- After hardware reset, use the panel’s ILI9320 register initialization and test a solid color. If reads work and pixels are wrong, check the high- and low-byte bus mapping.
