Making the board running

This chapter describes consecutive steps to make the board running.

Backlight

The easiest part is to make backlight working. The small separate board with 2-pin connector is a power converter for it. Unfortunately because no original PSU was available it cannot be said what voltage should be applied to this connector. For sure the backlight will lit (but how long?) when +10V power is provided to this connector. Where the plus and where the minus should be applied can be recognized thanks to descriptions on capacitor placed close to connector.

LCD and CPU

After that it would be nice if some pictures appeared on LCD. This is a bit harder and requires power supply with three voltages. The logic circuits must be working – connect

+5V to pins 8 to 10 of connector 1 and +3.3V to pins 18 and 19 of the same connector. To make LCD working +36.6V to pin 22 must be provided. Don’t forget to connect common

GND the module (pins 11..17). After turning on above voltages nothing happens – the software located in Flash waits for something. To kick it you have to bangle pin 20 of connector 1. It is suggested to connect the pin to + 5V through 1k resistor and solder switch button to GND. Now power the module on, wait few seconds, press the button and welcome screen will appear.

Now there is possibility to correct contrast changing +36.6V a bit. After longer wait it can be seen application screen.

Playing with the huge switch button located under LCD will effect in other pictures shown on screen.

Listening debugs

On the JTAG connector there is serial port attached also. Module with original software, during startup, prints there debugs. The signal voltage level is 3.3V thus voltage converter is required to connect module with PC RS232 port. Any of widely available RS232 converters can be used there, preferably with 5V supply, to do levels adjustment. As there is also +5V supply output on the JTAG connector, making such conversion should not be a problem.

Finally after wiring the module with PC startup debugs will appear on terminal.
