So here is the Sparkfun Max 7456 breakout board running the sample sketch talked about in the previous message.
No I guess it isn’t going to be here because you can’t paste jpegs into this forum. (but it’s easy! others have done it!) No, posting it somewhere else to link to it is not as easy as paste you’re done.
Anyway, it is a picture of the breakout board wired to the arduino with SAMPLE on the screen in the background so you could see how it is hooked up and that it works. Being able to post pictures quickly and easily would promote more precise flow of data. Using words to describe things is not as exact as a picture. but I digress . . .
hook up goes like this in the sketch;
#define RESET 0 //PB0
#define CS 2 //PB2
#define MOSI 3 //PB3
#define MISO4 //PB4
#define SCK 5 //PB5
So this is fun for a new person PB0, 2,3, . . . This is like being in someones neighborhood and not knowing they call XYZ street RiverRoad. On the map it’s XYZ everywhere. “Well then” they say, “you’re not looking at the right map!” “Everyone round here uses the map ya get at the drugstore in town.”
You’re not from around here are ya?.!"
So every time someone says, “I followed this and got it to work just fine”, as advice on how to do something you should just say, “You’re not from around here are ya?.!”
but I digress . . . .
So now I move on to getting another sketch to work from where I am at. Going to dfrasers message at the beginning of the 13 page Max7456 discussion he leaves two parts of a sketch that looks like it should help in making this more workable. Make the sketch our of both parts and it doesn’t work. Pin assignments
#define DATAOUT 11 // MOSI exactly what it says
#define DATAIN 12 // MISO exactly what it says
#define SPICLOCK 13//sck
#define MAX7456SELECT 10//ss
#define VSYNC 2 //INT0
So I’m not from around here, can someone help me to the history why this hooks up differently?
Is MOSI in or out?
Is ss also known around here as cs?
Off to look for some sketches that will work with the SAMPLE sketch setup.
If anyone knows way to find them, search terms, links, ect. it would be appreciated
