"hardware.ini" is incorrect since T8SG has PA for cyrf6936
; enable-cyrf6936 = B12
has_pa-cyrf6936 = 0

Corrected version with:
; enable-cyrf6936 = B12
; has_pa-cyrf6936 = 1

Now I don't understand how T8SG work with 4in1 module.

dc59, have you all protocols enabled? With the exception of Devo, DSM2/DSMX, and Nine Eagles (based on cyrf6936).

Can you provide real/working "hardware.ini" from T8SG?

Vlad,
I haven't looked at it yet, but do you know if we can detect the LCD driver by querying its registers? It is possible we could not create a new target for this Tx if it is only that change, assuming we can detect the case. I think we'll probably need a new target eventually anyway, but if we can get by without one for now, I might prefer that.

I don't see any register for identification. All control register are for write only, and one register for reading current status.

Moreover, we need different makefile for customizing hardware.ini. It will differ from devo7e-256.

I'm all for not creating another target and autodetecting it instead. If it can be autodetected, then you can ignore config file settings for radio and avoid extra target for ini file only.

Unfortunately UC1705 and its prototype NT7538 do not have any identification commands. On the other hand, there can be differences in behavior, either in controller or in other physical connections. Needs to be explored more, and if this is a prototype, Banggood should be notified to change something just for the purpose of easier configuration.

Possible ways to ID Tx:
The bootloader is likely different since they don't show the walkera logo on boot. I'm guessing they made some minor changes to bypass the screen initialization.
They may use a different flash chip. I believe these do have unique Id for each vendor. This may not work, since some users of the 7e-256 may swap the flash too, in which case we have no idea what to expect.

I think we will likely end up with a unique target eventually, because they've already indicated a willingness to rev the hardware based on feedback, and at some point it will likely be different enough. What I would rather not have is separate targets for 'rev1', 'rev2' etc. Until we get a better feel for their mode of work, I'd rather hold off on creating the new target. Probably at a minimum until some samples are available, and we can see what options we might have.

I agree with PB and victzh in trying to stick with 7e-256 for this release.

I was scanning through the data sheets for both UC1705 and NT7538 and noticed, that the behavior of the status register "enable" (or ON/OFF) when read out seems inverted between the two drivers. This could be used to differentiate between the two displays. Or maybe I'm just reading it wrong as it's late or the translation of the data sheet is bad or...:silly:

Maybe vlad could make a test build based on this? I'm too busy the next couple of days.

It's different company.
Actually, Jumper is not T8SG's company name , it's their RC transmitter product name, just like Walkera's "DEVO".

Devo7e, "lcd.c"
int c = contrast * 12 + 76; //contrast should range from ~72 to ~200 (contrast = 0 - 10)

NT7538 has 6bit "Electronic Volume", the same thing for UC1705, so it looks strange to adjust the contrast beyond the range 0-63, with default value 32.

More logical will be:
int c = contrast * 6; //contrast should range from 0 to 63

Is it possible that Devo7e LCD use other LCD driver chip?

I tried to use this build, everything works fine!
I format USB drive to clean all data and copy all files from "deviation-t8sg-v5.x.x-2017-09-06.zip" , no problem at all. :cheer:
