Hello,

A few comments to your code. You may already be aware of this, but I want to check.

This part in the end of your main() before the loop main-loop.

// TEST
         while  (ADC_North > 10)
         {
            if (m_conn_handle != BLE_CONN_HANDLE_INVALID)
            {
                mouse_movement_send(-MOVEMENT_SPEED, 0);
            }
            }
// END TEST

Will not do anything, because you probably haven't received any saadc callbacks yet, so your ADC_North is probably still 0.

I see in your saadc callback function, you call the mouse_movement_send() function, and you don't use the global variables, ADC_North, west, ...

Also, I see that you have two while loops in main. Reduce this to one.

But can you try to do the following instead of your while loops in this function:

ADC_North = p_event->data.done.p_buffer[0];

as you already have. Skip all while loops and their content in this function.

Then add the following in your main-loop (the one containing idle_state_handle(). The other one is never reached)

for (;;)
{
    run_mouse();
    idle_state_handle();
}

Then add this function something like this:

static run_mouse(void)
{
    if(ADC_North > 10)
    {
        mouse_movement_send(-MOVEMENT_SPEED, 0);
    }
}

If this doesn't work, I see that you don't check your return values. Try to print their values to see what they return.

Best regards,

Edvin
