HMLiberator
Hmm, the software for the HMLiberator† is (almost) working. It seems to respond as I hoped five out of six times. The next time it just seems to not do what I want. I’m not sure how to debug it, though, as I can’t really trigger an interrupt with the device in hardware debug mode.
This might take some thinking.
That said, it’s time to go home and build the appropriate cable so I can actually sling it in between an iPod and the HML itself for once.
† The HMLiberator is the PIC-based device I’ve been cobbling together to sit between the iPod and the Honda Music Link, translating the Mode 4 remote commands into Mode 2 commands. This will allow the user to keep using the controls on the face of the iPod, while the HML thinks it has one locked down and under its control.
