NHD-2.23-12832UCB3-40956 display in SPI Bus
« on: February 12, 2018, 07:37:06 AM »
Trying this display in spi bus and after the initialization, display screen is black, i.e. nothing happen.

How to validate that the SPI bus transfer is proper? Any single command, the device will react in some form.

Do you have any test cmd in this display, so that we can confirm that device receives the SPI cmd proper and operate for this cmd.
This will helpful for initial bring ups.

Please help.
