Be sure to read post #3 on the Warpquad thread. This is meant to supplement that information.

This section details modifying and installing the custom version of MultiWii using the Arduino development system

The MotoWii uses the Arduino development system for editing and installing the firmware. If you're not familiar with Arduino, please see the tutorials here:

I have used Arduino version 1.0.x (current version is 1.0.6), which is available for download here:

The MultiWii_MotoWii_RevB_V3 contains a folder called "MultiWii_MotoWii_RevB_V3". To open the sketch in arduino, browse into that folder and select the file "MultiWii_MotoWii_RevB_V3.ino". Make sure you're in the right place.

config.h should be the only file you need to edit. The only changes you'll need to make might be:

For Spektrum-compatible satellites, the radios may bind at either 1024 or 2048 resolution. The sketch is set for 2048, but if your receiver channels seem scrambled you may need to change #define SPEKTRUM 2048 to #define SPEKTRUM 1024.

To switch from Spektrum satellite to a PPM_SUM receiver, comment the #define SPEKTRUM line and uncomment one of the #define SERIAL_SUM_PPM lines that corresponds with the channel order in your transmitter.

To enable 125uS onshot mode on the KISS ESCs, uncomment #define ONESHOT. You'll need to short the J1 jumpers on the ESCs too for this.

To enable the discovery buzzer...Continue Reading
