Noting that there have in the past been a number of posts recommending the SAA1064 LED driver chip and also a number of instances where newcomers have required assistance, the attached "Getting Started..." tutorial is provided to help those new to the SAA1064 chip get under way with some circuits and code that is working.
As indicated in the tutorial, the SAA1064 has a relatively inconsequential Status Register what on has a single bit to indicate if the SAA 1064 has been accessed since it was last reset/powered-up. The example program with the tutorial includes code to read this Status Register which will hopefully help to indicate whether the i2c comms is working in the event that nothing is initially displayed on the LED displays as the reading of the Status Register should return either 0 or 128 but not 255.
