Comment out line 1334 and change it:

1334 ???// g_identifier = tft.readID(); ? ?// Get TFT ID ?3.95" = 0x9486, 3.6" = 0x9488

1334 ? ? g_identifier =?0x1581;

and see what happens. This forces it to assume the non-default parameters.

Subject: Re: [BITX20] W8TEE TFT /VFO BOARD - WHICH DISPLAY?

I wired the display up to a atmega 2560

ran your pgm and the serial said:

Serial took 0ms to start

ID = 0x1289

100 Hz

put these lines after it:

? Serial.print("g-ID = ");

? Serial.println(g_identifier, HEX);

and see if the ID is in the program. If your number does not appear in the switch/case block (lines 1336-1460), the code by default assumes the display is a 0x154 or 0x9341. If it is not one of those, try changing g_identifier to 0X9488 and see if that works.

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

tft =240 x320

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.
