TypeError under Mac OS #8

Open st20d opened 5 years ago

Hi,

With MacOS I don't get the script running.

First I must additional run sudo easy_install pip to get sudo pip install pyhidapi running and ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null to get sudo brew install hidapi running.

Maybe that's useful for the Help File.

Now the script is running but when I connect a device and try sudo python led-badge-11x44.py "Test" I get follow error code:

using [LSicroelectronics LS32 Custm HID] int=-1 page=1 via pyHIDAPI Traceback (most recent call last): File "led-badge-11x44.py", line 439, in <module> pyhidapi.hid_write(dev, buf[i*64:i*64+64]) File "/Library/Python/2.7/site-packages/pyhidapi/pyhidapi.py", line 638, in hid_write buf[n] = data[n] TypeError: one character string expected

Im Using MacOS Mojave 10.14.4.

Thanks for the install instructions! Added them to README.md

The type error looks like we broke python2 compatibility. python3 should work better.

@st20d is python3 an option on MacOS? The combination pyhidapi and python2 does not mix well. I'd avoid finding direct a solution for this, if possible. python3 with pyhidapi works well, and python2 with usb.core also does in the general case. This needs confirmation please what works on MacOS.
