I'm a newbie. And I'm not quite a programmer, I'm starting with Netduino and with some help I managed to blink the Led and with Mario's help it's now communicating using modbus (thanks again Mario).
Now I have a new dilemma, I need to receive some data using I2C and writing it to a register. I've studied the code from
I haven't tested it yet, but someone have some other example?
And Why do I have to put the resistors?
Some time ago I used an Arduino for a similar aplication and it wasn't an issue
Thanks in advance.
