I am totally new to avr-gcc, AVRs and embedded programming of any type! I am a semi-retired physicist and I want to build some measuring type projects for myself. I have been finding my way using the STK-500 and JTAG-ICEmkII package from DigigKey with avr-gcc and AVR Studio.
I want to try talking to some I2C chips (things like IO expanders from NXP)and it has been suggested that I try the AVRLIB library from Pascal Stang. I have compiled the i2ctest demo, and I get the console IO, but what I don't understand is how I enter things like binary or hex data?
Sadly the example is a bit light on documentation and I don't know enough C yet to be able to figure out just what I should enter from the console.
Can someone help?
I am using Studio-4.13.528 and the latest but one release of avr-gcc (a few weeks old).
Thanks in advance, Dean
