If you plug 2x keyboards in a system you will see both will sync the lock leds. Most operating systems sync the LED on all keyboards. In the Arduino HID library, there is a UsbEventCallback that will send any connected keyboards a change in LED state.. Is there any way to read the current system status of the LEDs? Code in the Arduino HID library does not sync the LEDs, but it can easily be done once the LED statuses are captured.

Here is an example of Arduino HID code for the event handler when the LEDs change state. Is there any possibility to implement the same in this Python library?

static void usbEventCallback(void* arg, esp_event_base_t event_base, int32_t event_id, void* event_data){
	if(event_base == ARDUINO_USB_HID_KEYBOARD_EVENTS){
	    arduino_usb_hid_keyboard_event_data_t * data = (arduino_usb_hid_keyboard_event_data_t*)event_data;
	    	Serial.printf("HID KEYBOARD LED: NumLock:%u, CapsLock:%u, ScrollLock:%u\n", data->numlock, data->capslock, data->scrolllock);
	    }
	}
}

HID does not seem to work on Raspbian GNU/Linux 11 (bullseye).

I am running the keyboard example from the readme.

Is there a way to make the mouse move on the screen instead of having it teleport to its position?

When sending characters thru keyboard emulation, and the host computer has a secondary keyboard installed with capslock ON. The characters sent from the Raspberry PI have the case invented. Example sending 'Hello' will result in 'hELLO'. Is there any feature to counter measure this?

In the current implementation, only relative mouse positioning is exposed to Python.

Is it possible to send absolute positions?

If there is a buffer structure reference that you are aware of I can implement the bindings and send a PR.

Hi,

Is this licensed as MIT or GPL?
In setup.py it's listed as MIT, but LICENSE.txt says GPL. I would prefer MIT, fwiw.

Thanks for a great library!

Hey there,

I don't understand how can i enable the AZERTY output, for kerboard type method.

Thank's in advance

config package build setup to include keymaps folder

What measure does the x and y move in is it pixels or is it something different. Also is there a way to bypass the 127 limit for the x,y movement in one movement without using a loop or calling the move method twice?

Hi, thanks a lot for this lib, helped a lot in my recent tinkering with Pi Zero.

I came across this lib onb PyPI, but when I wanted to go to Homepage I got 404 GitHub page. Nevertheless I managed to find this repo.

It seems that there is a typo in the package configuration, so instead of pointing to https://pypi.org/project/zero-hid/ it points to https://pypi.org/project/zero_hid/ with underscore instead of hyphen.

This is not strictly a issue with the lib, but I wasn't able to come up with any other way to report that, mainly because you set the email to a mock one.

Take care and happy new year 🎆

Thank you for the repo.

I test it with Linux raspberrypi 5.15.32-v7+
I was testing it and I was getting the current issue: [Errno 108] Cannot send after transport endpoint shutdown. This was because I was using a USB HUB HAT, after remove it, worked perfectly
