Tried to test Richards code, but seems i cant make the LCD work at all.
For starters the Backlight does not turn off.
What is the sequence that should be sent over the serial port to control...
This code is not for PicBasic dialect...

Here's a shrink down version for displaying messages from internal arrays no serial input involved.
practical if just an operating device with control buttons attach to the remaining 5 ports is...
yes that's a very good idea, the one I have tested are 1601, 1602, 2004

When B1=255
richard - 3rd October 2025, 16:15Well, ok then. BL stands for the back light. But where does it get set?
Ioannis
One var is B1 the other is BL, as in bl for bachlight .
I would need to paid more for properly named vars and valid meaningful comments

The backlight is controlled by 255d and 0d or 255d and 8d.
