Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I own an eXtreme backpack144 V1.1 with a 7" LCD mounted, supplied by WhiteWizzard. A few weeks ago I switched to VGA output (and did not note down the option list). VGA output works fine, but now I want to get back to the LCD again, but none of the OPTION LCDPANEL SSD1963xxxxx commands I tried brings the LCD back to life, the unit sticks to VGA output, LCD blank. My current OPTION list is CPU 252 /COLOURCODE ON /DISPLAY 24, 53 / LCDPANEL VGA / KEYBOARD UK /SDCARD 93,94 / LCDPANEL CONSOLE /RTC 15, 16 / HEARTBEAT ON. The unit is running MMBASIC 5.03.15

What commands do I need to issue to get the LCD going again? And, can I use both VGA and LCD and how? If part of the answer is "update to newer MMBASIC version " please point me to instructions howto (there is a PIC on the board, and a "mode" switch) I found an LCDPANEL RESET command in a manual but that seems not supported by this MMBASIC version

First you need to disable VGA

OPTION LCDPANEL DISABLE

The set up the TFT

OPTION LCDPANEL SSD1963_7_16,L,,142

Finally if you want to use the TFT as a console

OPTION LCDPANEL CONSOLE

Quote can I use both VGA and LCD and how?

No, it is either/or

To update the firmware see the instructions on the microbridge on geoffg.net. Your PCB has a built-in Microbridge

Lastest firmware version here Edited by matherp 2019-07-03

LCD is working again, thanks. Makes sense, the order of commands. I was probably scared losing all output. Keep up the good work on the mites I like the steady flow of innovation in software and hardware in this forum.
