Jack,

Never mind.? I added

case 0x9486:

and now it looks good.

Jack,

My display looks like the bottom picture below but my display is the Mcufriend 3.5¡° TFT LCD for arduino uno.? It identifies as g-ID = 9486.? However looking at the code around line 1335 there is no case for ID 0x9486.? Can you tell me what parameters go with this case?

Thanks,

Mike

What happens if you put this code in my program:

?

? g_identifier = tft.readID(); //

? Serial.print("ID = 0x");

? Serial.println(g_identifier, HEX);

? if (g_identifier == 0x00D3 || g_identifier == 0xD3D3) g_identifier = 0x9481; // write-only shield

? if (g_identifier == 0xFFFF) g_identifier = 0x9341; // serial

? // ? ?g_identifier = 0x9329; ? ? ? ? ? ? ? ? ? ? ? ? ? ? // force ID

? tft.begin(g_identifier);

?

starting around line 1335? The key is setting the identifier.

As a further test I ?tried some other code from "PD8W

?

?"

see below

Display working with various codes but it seems to fit on this one (PD8W'S CODE)

Jack, John, Vince......THANKS!!!!! ? ? ?It works!

?

1. ?modify mcufriend kbv.cpp?

In the mcufriend_kbv library, see the file MCUFRIEND_kbv.cpp.
There is a line near the top that is commented out:

"//define support_1289? // costs about 408 bytes" ? ? ?----- ( I uncommented?it)

?

?

2. and?

?

line 1332 0n my code ?I added ? ? ?g_identifier = 0x1289;

?

just before this code. ?switch (g_identifier) {

?

Recompile and now can see display - freq, s meter, etc.

?

As a further test

?

I un commented and commented each line below to see if the display would change?

?

Display appeared but not correct ?placement?

?

?

line 1344 ? ?g_identifier = tft.readID(); ? ?// Get TFT ID ?3.95" = 0x9486, 3.6" = 0x9488 ?2.8 = 0x1289 ? ? - when using this the pictures is as appears below

?

?

line1346 ? ? // g_identifier = 0x1289; ? ? ? I also tried this - same results as picture below

?

?

?

It looks like text size on some lines are ?to large or incorrect display line?

?

?see photo

?

running on an regular atmega 2560 for testing

ok, before the line tft.begin(g_identifier) put
g_identifier = 0x8989;

and see if it runs.? You may need to check on the arduino forum for other possible values.? I didn't see a chip number in the pic you posted.

I ran it? before.
It suggests trying? the defined option

One resulted in? id =0 and
when I tried the other option the id said? id =8989
