AVR 8515 LCD with serial Interface
A serial interface for the Truly MTC-C162DPLY-2N
2 line X 16 char LCD display
With this arrangement, the Truly display has a 4 bit parallel interface. The AT90S8515 controller converts incoming serial data to the appropriate 4 bit parallel commands and data. Incoming characters are written to the bottom line of the display and when a displayable character, that is a character that is not a control character, is received after a linefeed is received, the bottom line is copied to the top line, leaving a blank line on the bottom with the cursor set to the first column of the bottom line.
