A tft addin for pbp3

[ruijc]

I was looking on ebay and i could not find any 2.8" TJTCM24024.
The only TJTCM24024 i could find is a 2.4"

see here:
http://www.ebay.com/itm/2-4-240x320-...item20eaff07d1

Also the TJTCM24028:
http://www.ebay.com/itm/240x320-2-8-...item41998b289b


Maybe the 24028 means 2.8" and the 24024 means 2.4".

@Richard,
Can you double check you your display is really 2.4" or 2.8"?

Thanks

Regards
Rui

the 2.2 board before and after the flash chip added (w25q32bv)

[richard]

did a bit more fiddling with the buttons
we now have rounded corners and self centering title text , and self scaling title text size too.

the flash bit now has a flasheader cmd to read image nams and x y sizes .

this demo has the flash bits commented out

ps the button x,y value now is the centre of the button (was bottom lh cnr) and each button can have its own size still

[richard]

fixed touch module cs pin not initialised to unselected state on boot up and had some vars being used without being cleared first (real amateur hour stuff)

[richard]

now with sliders, might try to get the touch module on the spi bus next (should then be able to read touch x,y ps about 16 times faster than bit banging with shiftin )

Excellent work Richard

FIXED again

Richard, Seems you've done some fantastic work on using TFT's with PBP.

I have a 2.8" display of the same resolution, but I'm running PBP 2.60c which lacks the usercommand function. Is there any chance you could advise / produce a library that works with version 2.60 ?

[HenrikOlsson]

I won't speak for Richard but I'd take this as the opportunity you've been looking for to finally justify the upgrade PBP3 - you've now found a feature it has that you want/need ;-)

/Henrik.

[richard]

I won't say its impossible but


lets take one simple usercmd

GLCDSTR 2,2,buff

macro called is

GLCDSTR?CCB macro Xin ,Yin ,Bin
MOVE?CW Xin , _X
MOVE?CW Yin ,_Y
MOVE?CB high Bin, FSR1H ;load highbyte
MOVE?CB low Bin, FSR1L ;load low byte
L?CALL tft_str_out
endm

translation to pbp2.6

X=2
Y=2
@ MOVE?CB high _buff, FSR1H ;load highbyte
@ MOVE?CB low _buff, FSR1L ;load low byte
call tft_str_out

not too difficult but its messy and could get very ugly very quickly , as henrik says an upgrade looks good

Would love to upgrade, but being a casual user, and between jobs, upgrading is simply not an option for me at the monemt
