 ## Overview
-I added some LEDs on the [[rc:hw:quad:pitchou|Pitchou]] and just wanted to be able to switch them on/off using the radio. I could have bought something, but it would probably have been expensive, would have taken a long time to arrive, wouldn't be customizable, ... So I took an Attiny85 (smd version) and made a really small board that takes a servo PWM input, and can toggle three outputs.

 ## Code
-## Links
+Because I didn't want to bother with ICSP, I flashed a [[http://jtxp.org/tech/tinysafeboot_en.htm|bootloader]] before soldering the Attiny on the board. I wanted to use the same bootloader used by the [[https://github.com/sim-/tgy|SimonK firmware]] but couldn't find enough documentation to easily port it... Maybe later.
+The current firmware toggles between the three outputs, there's no "all off" position"; I didn't need it, and it turns the LEDs on when the radio link is lost or not established (if wired correctly), which can be useful.
+Current revision of the firmware is available here: {{:rc:dev:tinyrcswitch:tinyrcswitch_firmware_20141212.tar.gz|}}
