As suggested I am trying to get MCUFriend grafixtest to run.

After hard coding to use 16 bit I get this error.....

Is the Carrot underneath just a marker for pointing out the error?

C:\Users\Michael Hagen\Documents\Arduino\libraries\MCUFRIEND_kbv-master\MCUFRIEND_kbv.cpp:573:23: error: 'write_16' was not declared in this scope

???????? write_16(color);??????? //we could just do the strobe

?????????????????????? ^

Strange, "^" I did not put it there.

This error:

"error: 'write_16' was not declared in this scope"

suggests that in your code you used:

#define write_16

which probably needs to be written:

#define WRITE_16

since most C programmers write symbolic constants in upper case letters. C is case sensitive so?WRITE_16?and ?write_16 are different symbolic constants.

Thanks,

I added the 16Bit define in C file.

now get error in Jack's code?

"error: 'write_16' was not declared in this scope"

Maybe there needs to be a ref to an external something?


I think my correct display type is "ILI9481"? Which I have seen 0XDBDB
returned in a test?

I looked at Rinky Dink documents.? I looks like it uses the Data d0-d15
on the top half of the right side double connector.

D37 and up.? The top pins are 5V.? Then d39 & d41 on the right side for
Wr and Rst.

d36 & 38 on the other side for RS and CS.? They say that's all on the
Mega they use on that connector?
