Ibus + ipk = ...

That's good confirmation.

Would seem to be a bit of a limitation in the design, but could well be.

Brill! Yes, it doesn't work well without the resistor.

Hmm, not sure if this of use.

Sending 3B 06 F0 43 82 00 01 xx clears the display.

Changing the 01 to other numbers causes the display to show garbage. Maybe this is some kind of pointer to what data to show. Memory addresss? Page?

Hi Leafie,

Great! The app's not in a state anyone else could use it really as I hack it about and run it without building an executable.

Searching the web for the newly discovered sequence and I've found some really good info here:

Trying it out it seems to work (almost!)

I've put a post there to ask for a bit more info......

Congrats Leafie ! Fantastic info ! I'm just about to go to the car and capture some data !

What did you manage to send to the display and how ? What commands you used ?

See you later here

Trying to reverse engineer so sent:

3B 1E F0 43 00 23 00 00 2A 1B 01 [41 20 48 61 72 64 20 44 61 79 27 73 20 4E 69 67 68 74] 00 xx

Bit in brackets is the text. The final 00 may be the terminator.


Then:

3B 06 F0 43 82 26 00 xx which is close to my sequence.

I'm guessing the first command somehow loads the text and the second one causes it to be displayed.

More experimenting to do.......

This is the greatest achievement so far (that I know) ! Keep working, Leafie

Going now to the car, see you later
