Hi gang,
Maxim was kind enough to send me two MAX6958 samples. (Mixed-signal and digital signal processing ICs | Analog Devices) lSince the Arduino speaks I2C I'm scratching my noggin on how to send input data to this chip (driving a 4 digit 7 segment LED display).
Pointers to relevant existing code welcome.
My desire is to input data from an IR based tachometer and out put this to the MAX
Looks like you are cutting new ground. A Google for 'Arduino and MAX6958' showed this thread as the top hit. That sort of suggests no one has done it before.
Not too sure how skilled you are but all you need is the I2C library, see:-
http://www.arduino.cc/playground/Learning/I2C
and the data sheet for the device:-
http://datasheets.maxim-ic.com/en/ds/MAX6958-MAX6959.pdf
A quick look shows there are two types of MAX6959 an A and B suffix. These have different master addresses. Read the data sheet for what values need to be in what registers. You can ignore all the timing waveforms as these are taken care of by the Arduino library.
Best of luck, and do post you code when you are through.
Oh joy. I get to get bloody knuckles....
