bullseye convert hyperpixel-touch script to python3

[pwr33]

python2-pip gone and that sort of problem, so convert it to python3?

simply change the shebang to python3

basically you use some odd old python2 function file(), converting to python open() works ok except for the se file which fails on the os.dup(). cant find the old python documentation on the file() function it is that old...

any ideas

Looks like this is a very similar set of changes - https://github.com/pimoroni/phat-beat/pull/37/files

For stderr:

se = open("/dev/null", "ab+", 0)
os.dup2(se.fileno(), sys.stderr.fileno())

Works for me on Python 3.8

Hi, been a while, just spent a bit more time on it, it is now failing on the line below
bus = smbus.SMBus(3)

does it need a udev rule or something?
there is no /dev/i2c-3

Tried compiling the overlays and that gave warnings, so I'm thinking its the same as with the hyperpixel4, stick with buster if you want the touch screen ???

OK, it is now SMBus(11) on buster and bullseye

And to stop a segfault, change

/usr/lib/systemd/system/triggerhappy.socket
[Socket]
remove ListenStream=/run/thd.socket
replace with ListenDatagram=/run/thd.socket

works for me anyway
