Hi,
in order to provide compatibility with the iphone 3-button-remote controls it would be great, if the functionality of the following RF-Buttons (decoding from button state to USB HID events in the purepath-headset-master) could be extended:
a) "Play-Pause RC-Button"
b) "Output Volume Increment RC Button"
c) "Output Volume Decrement RC Button"
I think of a checkbox (in wireless configurator for the headset master) "enable I-Phone compatible button a)/b)/c) buttonstate-to-HID-conversion". When checked, the master decodes RC buttons a)/b)/c) as follows http://www.wikihow.com/Use-iPhone-Headphones to the corresponding HID-Events....
//Edit: or a "switch" for the USB-Soundcard (like e.g. enable/disable mic bias on some soundcards) to enable/disable the additional buttonstate-to-HID-conversion functionality
Is it possible to extend the master firmware functionality in order to support this interesting functionality?
Thanks & Regards
Jasmin
PS:
Regarding the slave, the only thing needed there is a tiny circuit, that decodes the 3 different remote-button-resistances (for I-Phone (1) and Android (2) ), connect it to 3 GPIO Pins of the PurePath IC and assign RC Buttons a)/b)/c) to it
