I am reaching out with a technical inquire about the display DT024CTFT, which we are currently using in one of our products (please see the connection diagram attached).

The signal backlight2 is connected to a PWM output used to regulate display luminosity. Note that, since the RESET signal is maintained at a high logic level, the display is reset using the reset command through firmware.

We have found in our end-of-line testing that, after programming the MCU, and while power cycling the system, the display occasionally halts in an all-white state and stops responding to FW reset commands.

I have tried to read ILI9341 LCD controller ID (D3H), but it doesn’t work until now, the EXTC has been high, the result as below:

1. The leve1 command read/write is OK. The leve2 command (EXTC should be high to enable this command) write is OK, read by FMC port is OK but read by SPI is fail.

2.ID1/ID2/ID3 (leve1 command DAH/DBH/DCH) can be programmed by user(level2 command D1H/D2H) successfully .

3. The LCD acknowledges data is different between FMC port and SPI port, for example the 09H command, the first byte data will be invalid, when read by FMC... (More)
