Explore HIDAPI callback function

Try to implement a callback read using a low-level function from the HIDAPI library - read_callback

• https://askubuntu.com/questions/1447628/how-to-implement-generic-hid-read-with-libusb-interrupt-callback

This function has to be additionally implemented to a python HID wrapper like easyhid

The parent project pyspacenavigator, which supports only the Windows platform uses a callback function to the smooth read

• dev.set_raw_data_handler(lambda x: new_device.process(x))

PySpaceMouse on MacOS ARM M1

I have tried to install PySpaceMouse on MacOS M1, but it doesn`t work.
Is there anybody who fixed this issue?

I have installed hidapi trough brew install hidapi.
My result from basicExample.py is there:

[docs] Setting permission rules on Raspberry Pi fails [fixed]

Following the documentation for installing the dependencies, I ran into a Permission denied error with:

sudo echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' > /etc/udev/rules.d/99-hidraw-permissions.rules

The solution was to use sudo tee:

echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/99-hidraw-permissions.rules

button mapping modifiers for space pro bluetooth

I am emulating space pro bluetooth with esp32 and my button mapping same as yours. But modifier (like ctrl,shif etc) bits doesnt work.

I'm asking this question here because I couldn't see the Space Pro Bluetooth description in your code. Is there a specific reason for this?

Test HIDAPI `set_nonblocking`

Look at set_nonblocking and test it wit the library.

roll/pitch/yaw Spacemouse Wireless

Dear Jakub,
Thank you for your great contribution!

I had some issues when I changed from USB to wireless Spacemouse, but I found the solution here (the byte-array issue that was solved here) I dont think it is implemented in the current version that is downloaded from PyPi however.

My next issue is the fact that rotation doesnt show any reaction ( roll, pitch, yaw). I'm testing on a beaglebone blue running some new debian release. I tried to change channels in the pyspacemouse.py similar to the wired versions, but no change there...

When I connect the device, i get 5 HID devices popping up..

Best regards
Viktor

Latency of Data Reading

In a Python application with a SpaceMouse Wireless and SpaceMouse Compact we have very high delays when reading data.
We get the first values after initiating a movement after 100ms, but after reaching the zero position again it takes about 1-2 seconds until the values return to zero.
Is this problem known or are certain filters applied?
We are using the pyspacemouse package, and the 3 methods open(), read(), close().
Here is my code:

Thank you very much for your support.
