#Does the arduino wire library use interrupts code#
This sample includes both a read and a write example with the Arduino code handling both. Hopefully not so severe that you can’t make it work relatively easily. There shouldn’t be any syntax errors, but by extracting and making a sample program, I may have introduced some other problem. First off, while the format is similar to what we use on the robot, I can not test this out to ensure there are no errors as I do not have the hardware available. Sorry for it being a little longer than I intended. OK, here is some sample code that should allow you to communicate between an Arduino and the cRIO. runs once every time state changes to 2 runs once every time state changes to 1 runs once every time state changes to 0 Wire.requestFrom(1, 1) //Request data from slave device (the sidecar) Wire.begin() // join i2c bus (address optional for master) Int d = 999 //arbitrary int used for state change stuff
I want the Arduino configured as master and the sidecar configured as slave. Would this code work? All I need to do is have the Arduino receive one byte of information at a time. Is this possible, and how can it be done? I know nothing of LabView (which is what my team uses to program the robot) but I know quite a bit of arduino C. My team is working on a project that involves the digital sidecar sending information over I2C to an Arduino Uno (R2, if it matters).
