Designer or ViSi: Loop Back Testing with a PIC MCU


Number 4D-AN-00050
Difficulty Medium
Supported Processors PICASO
Supported Environments ViSi, Designer


This document is about basic asynchronous serial interfacing of the 4D display module with the PIC18F45K20. It contains a simple but helpful information on how to test the data information being sent by the PICASO serial port to a host controller in particular the MICROCHIP PIC18F34K20. The system is arranged such that the information data is sent by the PICASO display. This information is then received by the PIC18F45K20 and sends it back for the screen to display.
