How do I use the "I2CHelper"?
Hello how do I use the I2CHelper library?
Has anyone got an example?
I'm asking because I'm new to object oriented C.

I2CHelper myHelper(sda, scl); // replace sda and scl with the pins to use
main () {
myHelper.setFrequency(500 * 1000); // set the frequency in Hz
// personal preference here, I write 500 * 1000 rather than 500000 for 500kHz, it makes it more readable
uint8_t dataByte
myHelper.readByte( deviceAddress, registerAddress, &dataByte);
}
You can use any of the functions listed as public in the header file in the same way. The names are fairly self explanatory. http://mbed.org/users/ethanharstad/code/I2CHelper/file/51de41e0e0c9/I2CHelper.h
The header (in theory) tells you all you need to talk to the library, you should only need to look at the .cpp file if you want to know how it does it.
