Hi All,
I just got my new Papilio Pro and I was trying the examples from DesignLab. I've been playing around with different examples (Audio, VGA, etc.) and they work fine. But when I run any of the VGALiquidCrystal examples thye are just displaying two rows of green squares but no text in there.
The following screenshot (LCD_Demo.jpg) shows the results I get from the "LCD_Demo" example.
The VGA demos work fine (see screenshot - VGAHelloWorld.jpg)
Just fyi, I'm not using any Wing, I'm just connecting 6 pins in the CH Wing2 port to the VGA cable (V-SYNC, H-SYNC, R, G, B, GND) as in the screenshot - DirectPinout.jpg.
I am wondering if I am missing anything here. Do I require to connect anything else? Working with a real Liquid Crystal display needs to connect a couple of signals (rs, enable, data, etc.) but is it also necessary in this modified version? If not, what do the pins in the VGALiquidCrystal() call mean?
Regards,
Andres
