welcome to DPV technology.In this video we
will see how to solve 2.4 inch TFT problem
with arduino. this is one of the cheapest
2.4 inch TFT display,but the problem of this
display is that most of this will not support
the commonly available TFT display programs
for arduino. when we upload the programs ,it
becomes white.
so let us fix it.
now we have to download three libraries for
this tft -Touch screen library, TFT LCD library
and gfx Library from adafruit.the link of
these libraries are given in the description
of the video.
you just download it and then unzip it.then
you... then 
we have to place these three libraries in
the arduino library folder .so copy and go
to your arduino library folder.program files->arduino
and libraries .and you place here.
I have already downloaded it.
so you have to place it here .now to solve
this problem you first open your arduino IDE
and then go to examples and then go to TFT
LCD library master and then go to first program.
then you without doing anything you upload
it.here you see the screen is white right
now.
it is done uploading.
so it is uploaded.so now you go to serial
monitor.we will be able to see that this is
an unknown LCD driver chip with 6809 address.
so, that is why this problem is happening
actually.
so you cut it and then you go to the following.you
go to here in the program.
you can see that there are some identifiers
are written here.
one is 9325, another one 9328, 7575, 9341,
8357.these are in hex value .actually these
are the driver's address of the LCD,of the
tft.since our driver driver address is not
,not any one of these.so that's why the LCD
is white in this time .so that's why it is
coming unknown
lcd driver chip.
so now for this ,to solve this problem what
we have to do is that we have to comment from
this line to this line first of all .then
first you comment it by using slash and then
star and again you star and Slash. then what
we have to do right now is that you have to..
you have to put this number here first.
then if it won't work then you copy this and
paste it in place of identifier.
similarly if it will not work then you have
to copy and paste it here.
so you have to use trial and error method.
so first of all let try with this one .we
will try from the last one.
so control c .. copy .now we will paste it
here.you paste it 0x8357.this 0x means hex
number.
so now you upload it.so you see it is uploaded
but the screen is still black.again you do
it ,you try with this.control c and you paste
it here and you upload it.done uploading but
the screen is still white.so this is also
not work.now we try with this one-9325.so
first control c-copied and paste it here.
now let's upload it.
owww it's working.
you see now it's working ,it's coming.
it is written in the program you see done.rounded..these
things are coming that means it's now working.
so for this display, we have to use this 9325
.for other programs we have to ..similarly
for other programs we have to do the same
thing.
you go to examples and then then go to your
your TFT LCD master.
suppose you want to bitmap or paint.
or go to bitmap and open it and you do the
same thing .you first you first comment it
from here to upto this and then you try with
0x9325 and you change your image file name.here
is the image file name.
if you have inserted your image in the SD
card .so you have to change it otherwise this
program won't work because this is loading
image from SD card .so you have to first insert
image on the SD card .if you don't know how
to do this , you can watch our videos on TFT
LCD display .so I have already I have already
inserted two images in the sd card woof.bmp
and tiger.bmp.so lets see it.sd card is here
.I have to first insert it .you have to first
insert it.
in this SD card I have kept my two bmp files,bmp
images.
one is tiger.bmp and another is woof.bmp.
so lets first insert it and then you upload
it.
you see it is uploaded and images comeing
here .it will work in most of the cases.
thank you for watching this video
