Well done Greg, do try with 3x3 then we have a choice.

I've done some 3W x 5H Characters.

Haven't tested them on screen yet though. Got to write the routine to print them Paying the mortage gets in the way sadly


`*** Eeprom Data Storage 0-255 bytes (This does not affect program memory) 3W x 5H matrix ***

`EEPROM 0,(First 20 bytes reserved for other program functions)

`EEPROM 20, (219,219,219,219,32,219,219,32,219,219,32,219,219,219,219) ;Store Big Digit "0" in eeprom
`EEPROM 35, (219,219,32,32,219,32,32,219,32,32,219,32,219,219,219) ;Store Big Digit "1" in eeprom
`EEPROM 50, (219,219,219,32,32,219,219,219,219,219,32,32,219,219,219) ;Store Big Digit "2" in eeprom

A lot memory needed that way, you can use the binary way if you want.

A zero this way

111
101
101
101
111

gives 7,5,5,5,7
using high and low nibble gives 'EEPROM 20,(75,55,70)

That's good Wilfred thanks. If we get it working using bytes then I can convert it to bits later. The bit manipulation for the Picaxe Basic is a bit limited. That (zero) would fit into two bytes quite nicely just ignore the last bit. I'll fiddle with the software a bit now.

Heres some 3x3 numerals

0: 201,205,187,186,32,186,200,205,188
1: 32,32,203,32,32,186,32,32,202
2: 201,205,187,201,205,188,200,205,205
3: 201,205,187,32,205,185,200,205,188
4: 203,32,203,200,205,185,32,32,202
5; 201,205,205,200,205,187,200,205,188
6: 201,205,32,204,205,187,200,205,188
7: 205,205,187,32,32,186,32,32,202
8: 201,205,187,204,205,185,200,205,188
9: 201,205,187,200,205,185,32,32,202

See what you think.

edit Here is a screen shot of the numbers.

Hey they all look good apart from the 4 can you add another bit on that?

Don't forget we need a '0' Zero

[GregsGarage]

Peter,

I have changed the 4 and I did do a zero, just forgot to draw it. The codes I wrote by hand so if a chacter doesn't look right its probably an error on my part. I have edited the above entry to reflect the changes.

Edit Just found and corrected a couple of mistakes on the above table, check that you have the corrections if you already have copied it to your program, the 9 was wrong.

I'm working on the software now Thanks for the BIG numbers. I'll load up your 3x3 ones for testing first.

Demo of Greg's BIG numbers

Bit of a software nightmare, but after three hours graft got there in time to celebrate with a bottle of vino.

Now just got to do something with them!!

Code needs tidying but we have proved the concept and it works!

We can tinker with the design/size of the numbers.

My wife wasn't impressed that I had to interrupt an ebay session so I could check on your progress.

The numbers look good!

P.S. My wife thinks they look good too!

I'm working hard on the Master to incorporate these large numbers, anyone else want to have a go at different styles using the 3x3 matrix.
