[vc_row][vc_column width=”1/1″][vc_column_text]The serial UART 16×2 LCD allows you to control a parallel based LCD over a single-wire serial interface. The serial LCD takes care of all the HD44780 commands allowing seamless integration with any micro that can communicate over a wide range of TTL serial baud rates. In this post, we will explain how to flash the firmware to the pic MCU on the module.
