Hello,
So I'm using nrf52832 with sdk15.2 and I'm trying to connect a joystick to the adc pins and have the joystick to move the mouse instead of the buttons and having issues with that. I have successfully combined both SAADC and BLE_HIDS_MOUSE examples, created a global variables to store the adc values and used them to try changing the "case BSP_EVENT_KEY_1:" to them instead. first problem am having is that the "case" loop is not allowing an integer value to it so i tried a while loop and still am not able to see any changes in the mouse. So am not sure if I should change anything in the mouse_movement_send function or change anything in the hids_init function. I will attach the code.
So basically my problem is that am trying to have a joystick moving the mouse instead of buttons. and the joystick is connected to 4 ADC pins

I'm using 'p_event->data.done.p_buffer[0], [1], [2], [3]' as the output of the adc and storing them in volatile integer 'ADC_North, west...', each direction is connected to a different adc pin and the values shows in the terminal (PuTTY) are correct to my need. I now want to have the mouse move in accordance to the joystick, by having conditions like of when the value of the ADC_North > 10 the mouse moves north. This is happening in 'bsp_event_handler' function.
Note: parts of the code are commented out for testing purposes.
Thanks,
