Hi,
I have a V3 development board which i have had for a few years.

I have not sofar used the 7SD or LCD and now that i am attempting to use them neither of them appear to be working.

The LCD seems to be illuminating all pixels of the entire first row.

In flow code all seems to working well.

Is the LCD a plug in type module - it appears to be but I dont want to force it.

Also any testing advice would be appreciated.

Regards

Hello,

The LCD seems to be illuminating all pixels of the entire first row.

This indicates that the LCD has not been initialised. You will need to call the LCD start function to get the LCD to clear itself.

Check your Flowcode clock speed matches your crystal speed and also make sure that the Flowcode configuration is set to XTAL.

Is the LCD a plug in type module - it appears to be but I dont want to force it.

No dont force it the LCD is permanently soldered onto the Dev board.

The above should also apply when trying to get the 7seg displays working.
