Programming 633 with micro

[monkey9119]

Hi, Im trying to program a 633 with a atmel mega16 micro using codevisionAVR. The development board has a UART which i have enabled to 19200 baud, 8-bit, 1stop, no parity. I am confused as how to send a packet properly to display characters on the LCD. Any help would be appreciated. Thank you.

Many times, the CRC is incorrect. Here is a link to a debugger screen shot of the exact bytes in the exact order to send to update the screen Please hard-code to send these bytes to the LCD as a test.
