[SHARED] iOS interfacing – Frequency Shift Keying (FSK) from Arduino
April 12, 2012
So, it turns out that I’m probably not going to use the Hijack approach to getting serial data from my Mindflex into my iPhone. This is mainly due to the fact that I have the majority of the components to build a similar system from scratch. The difference will be that I will not use the iPhone’s battery to power the system; I will use an external power source. I intend to follow the steps detailed in this forum discussion that I found on Arduino’s website: Arduino–>FSK—>Iphone (OpenframeWorks)
Here is a snapshot and the corresponding schematic of the setup of the parts:
NOTE: If you don’t mind jailbreaking your iPhone, the setup documented here interfaces the iPhone through the 30-pin dock at the bottom of the phone. It allows for a faster baud rate and easier access to the iPhone’s power source. Apparently you have to buy the Redpark or Legacy (?) device for ~$60, however.
