Custom character creation

TC

Hello all,

I am working with a Noritake display and I would like to make some custom characters, but Noritake has it's own format for the characters. On a standard display (HD44780 for example), each BITE of character data is arranged in rows. So, a custom character for a standard display needs 8 BYTES for a 5x8 character. But the Noritake displays use a different format. Starting at the upper most left character pixel, going from left to right, and down each row storing each 8-bits. Storing 5 BYTES for a 5x8 character.

Here is an example of what I am trying to explain.

What I would like to know is if anyone might have an idea how to use the prop to convert from a standard 5x8 format, to the Noritake 5x8 format? I don't want to have to reformat custom characters that others have created and posted on websites. And take advantage of custom character generators.

Thanks
TC

This can work. It's not tested and maybe a bit slow:

VAR
  byte standard[8]
  byte noritake[5]

PUB convert : i | p
 repeat i from 0 to 4           'clear all pixels
   noritake[i] := 0
 repeat i from 0 to 39          'copy every single pixel 
   p := standard[i/5] >> (i//5) & 1
   noritake[i/8] |= p << (i//8)

Wonderful, I will give it a try later. Thank you.

I just had the chance to test it, It works great. Thank you

Untested

VAR
  byte standard[8]
  byte noritake[5]
PUB convert
  noritake[0] := standard[0]><5 | standard[1]><5<<5
  noritake[1] := standard[1]><5>>3 | standard[2]><5<<2 | standard[3]><5<<7
  noritake[2] := standard[3]><5>>1 | standard[4]><5<<4
  noritake[3] := standard[4]><5>>4 | standard[5]><5<<1 | standard[6]><5<<6
  noritake[4] := standard[6]><5>>2 | standard[7]><5<<3
