PIN.TOUCH and streaming

[AndyGadget]

I've been away from Annex for a while other things have been taking up my time but looking to pick up a couple of projects soon.
(No reflection on Annex - I still think it's the best development environment for ESP32 by far :¬)

Just wondering Francesco, did you look at the bug I reported in Fernando's TTGO radio thread about TOUCH on the GPIO pins not working when the ESP32 was streaming?

From the thread :
I'm polling three pins with the pin.touch command every 200ms (I've tried less frequently too) and I'm reading values of around 90 when not touched and less than 20 when touched on each pin (actually connected to drawing pins as domed circular buttons) before the command to start the stream.
After the PLAY.STREAM command, it appears that one read is made of the pin and then will return that same value despite further touch / release.
I've proven this by (correctly) reading the pins several times on startup then including a pause before streaming during which I'll untouch the button. The read immediately after the stream command will return the untouched value.
After a PLAY.STOP the touch pins work correctly again.

This was the routine I was using to test :

Code: [Local Link Removed for Guests]

pause 500

nl$ = chr$(10) + chr$(13)
wlog nl$;nl$;nl$

PLAY.SETUP 1,50
play.stop
play.volume 10

for x = 1 to 50
  wlog pin.touch(12),
  wlog pin.touch(13),
  wlog pin.touch(15)
  pause 200
next x

pause 5000
wlog nl$;nl$

PLAY.STREAM"http://162.252.85.85:7858",50000,,1

for x = 1 to 50
  wlog pin.touch(12),
  wlog pin.touch(13),
  wlog pin.touch(15)
  pause 200
next x

pause 20000
wlog nl$;nl$

play.stop

for x = 1 to 50
  wlog pin.touch(12),
  wlog pin.touch(13),
  wlog pin.touch(15)
  pause 200
next x

pause 5000

HI,
I need to check as this point should be already fixed.

Need to setup an esp32

[AndyGadget]

I haven't tried this with a more recent release so you may already have sorted this.
I don't have access to my workroom (what my wife calls the 'guest room' ) at the moment.
Not urgent so I'll try it in a couple of days to save you the trouble of setting one up.

Problem fixed in the version 1.48.3

[AndyGadget]

This still appears to be an issue in 1.51.1 and is present for any stream; radio or MP3 as the test program below shows.
This is running on a TTGO Display ESP32 board with an I2S decoder / amp attached.
The wlog will only show correct PIN.TOUCH values after the stream has ended.

Code: [Local Link Removed for Guests]

pause 500
pin.mode 35, input, pullup
interrupt 35, stopall,2

Vol = 2
PLAY.VOLUME Vol
s$ = "http://162.252.85.85:7858"

wlog "Starting stream"
'PLAY.STREAM S$,50000

PLAY.MP3 "/3C.mp3"

do 
  t12 = pin.touch(12)
  t13 = pin.touch(13)
  t15 = pin.touch(15)
  wlog t12, t13, t15
  pause 1000
loop

wait

Sorry, I did the wrong answer previously.
Ok, now I understand, you are talking about the pin.touch (there was a problem with the touchscreen too when the sound was playing that I fixed previously).
