M5Stack Core2 V1.1 Display Problem

[cicciocb]

this is the H/W pin and should be 0 when you touch the screen
This should be responsive .....

[cicciocb]

I'm uploading again, I did a little fix .... maybe is the good one.

Try this one (save 1.52.9)

[coolj]

no, there are only sporatic zero's believe me, wen i hold my finger on the display

[cicciocb]

You should try this :

Code: [Local Link Removed for Guests]

'test 2
do
touch.read
print pin(39)
loop

If this don't work, maybe you must power off / on the module

[coolj]

the update-time is 21:50 ... is this the last?

[Local Link Removed for Guests]

[cicciocb]

Yes. You have the wrong time, probably the GMT (-2 Hours)

the same ... always 1 with sporadic 0 even wenn i leave my finger on the display.

i catched one zero for you

[Local Link Removed for Guests]

[cicciocb]

Very strange, this is an H/W pin, it should work all the time.

Maybe the controller require an initial setup but now is too late.

My bed is calling me. Tomorrow is a working day for me.

Have a good night

[coolj]

for me also, have a good night

and thanks a lot

my last test
this code works ...if i leave my finger on the display the wlog always printed the position.
If i removed my finger, the wlog stays still.


'touch_test
I2C.SETUP 21, 22 ' set I2C port on pins 21 and 22

wlog "Startup"

init:

touch_int = 39: pin.mode touch_int,input,pullup: interrupt touch_int, touchi
touch_x=0: touch_y=0

tft.fill black

do

loop

wait

sub FT6336U_read(touch_x,touch_y)
i2c.read_iobuff(0), 56, 5, 2 'use the IO Buffer 0 for reading
if iobuff.len(0) = 0 then
wlog "No communication"
touch_y = 0
else
touch_y = (iobuff.read(0, 0) and 15) << 8 + iobuff.read(0, 1)
end if

i2c.read_iobuff(0), 56, 3, 2
