Have ported the Raspberry Pi code, for the TEA5767 FM radio receiver, over to the CubieTruck. Because the TEA5767 only employs the "normal" 4 wires for I2C, and because WiringPi is just a wrapper around other libraries, the porting was easy. Short version: had to swap out libraries and rewrite the code that opens the connection to the chip. Everything else remained the same.
One oddity noted with compiling with the math library. The following works on the RPi but not on the CubieTruck (it triggers an "undefined reference to round" error):
gcc -lm -o mute mute.c
However, the following does work:
gcc -o mute mute.c -lm
Go figure... Notes available shortly.
