Hi, I’m trying to get the uLCD-144(GFX) to work in the SGC mode. I send 55hex (autobaud), 51hex 6hex (set the baud rate to 9600) and then 4Bhex FFhex FFhex. (set the background to white). This is all sent at 9600 baud using terminal inside of Workshop. I’m using a Sparkfun breakout board for the FT232RL to communicate with the uLCD-144. (an NPN transistor circuit is connected to the DTR signal on the FT232RL module)

I can verify the data is getting to the LCD module using an oscilloscope. There is nothing on the display and there is not any serial response from the uLCD-144 module. (no ack or Nack) When I power up the module, the display screen comes on green and shows uLCD-144(GFX) 128x128, and version information for about 5 seconds. There is not an SD card installed. I don’t have a uUSB-CE5 to communicate with the uLCD-144.
Any ideas what I doing wrong in the communication with the uLCD-144?
