Hello everyone,
Before I start, I am a student in Year 12 (Lower Sixth Form) and while my experience with Picaxe Chips (in general) is pretty substantial, my programming skill and understanding of data communication is poor. I am trying to set up a 4-digit seven-segment display using a 28X2 Picaxe Chip and a MAX7221 Driver, with the intention of displaying whatever data I need on this display, be it integers, decimals or characters (I understanding not all characters/symbols can be displayed given the restriction of 7-seg arrangements). I'd just like to be able to have lots of freedom with what I can display. I've set up a simple circuit, up until interfacing the MAX7221 using an SPI interface. From here on my knowledge is very limited. I'm not sure where to start, how to set up initialization routines (the picaxe SPI setup commands) and the other complicated programming!
ANY help would be very much appreciated!
