Hi guys

Just thought I'd post on how I got the LCD working as I've seen a few people looking for it.


IC2 20x4 Screen https://www.ebay.co.uk/p/Iic-i2c-twi-Serial-LCD-2004-20x4-Display-Shield-Blue-Backlight-for-Arduino-YK/2292368412?iid=263560227889

Connections: GND to a Ground Pin, VCC to 5v Power, SDA to pin 20 and SCL to pin 21


Add your device through settings leaving the address as it is

Create your output as the base (Display, LCD, etc)

Create 2 outputs (No device), use offset 6C40 and offset 6C4D, make sure value type is STRING, check the Substring and use 0 to 12


Edit your "base" settings, and choose Display,
Select USE on first line and choose your first output you just made with offset 6C40, click on the blue picture top line and use ????????? (fill the whole line), do the same for the next output you made 6C4D and use &&&&&&&& as above,


Save everything and, have a look. Now its just to format the screen to get them in the correct position. Simply edit the base file and add a few spaces in

Hi

Thank you for the guide !

AT FIRST: This is just for PMDG 737 NGX and will not work for Standard Aircrafts or other manifacturs !!!


Please note.... A Guide should explane the thematic.... Not show only your situation.

For example you say the user should let settings fir IC2 Adress as default. Thats Right in your situation. But if user have a other Display or maby the same but a other charge with a different IC2 Chip.... Then the adress can be already different and your "guide" is wrong.

Same with the Settings in the Blue Display field.
Here your right.... You "can" fill the whole line with "???????" but thats a wrong technic. If you read a String with 13 Bytes ( Substring settings) then it will include 12 Diggits of information ( The last byte is the terminator) .... So its high recommend to use also 12 Placeholders (? for example) but not more.
In This "easy" system mobiflight will simply ignore the unneeded placeholders at the end.... But in a complex Config this will occure in Problems.

I hope you not dislike my comment. ... But please if you recommend things to other users then try to explane it correct and reproduceable.
