Thanks Zoot.
This is what is running:


[code]
DISPLAY_RGB1:        
  FOR tmpB1 = 0 TO 255 step 8
    tmpB2 = tmpB1
    tmpB3 = 0
    
    LOW ChipSel
    DELAY_MS 1
    DO WHILE tmpB3 < 64
     
      READINC Ltr_Space + tmpB2, tmpB4                                 
      tmpB4 = tmpB4 * color
        SHIFTOUT DataIn, Clock, MSBFIRST, tmpB4
      INC tmpB3
    LOOP
        DELAY_MS 1
        HIGH ChipSel
      DELAY_MS 100
  NEXT
  RETURN 
[/code]
The problem happens when you change the DO WHILE tmpB3 < 64 to anything higher (in this case 127)

 

DO WHILE tmpB3 < 127

 

I do see strange results for anything over 65 or so. I think this is because of the 64 byte buffer in the controller that the documentation (attachment) indicates. If this is the case, why have DataOut?

 

 

I also had some problems following your previous posting. In particular:



[code]
messagePntr = address 'point to data address of first character of text string 
[/code]

 How do I find out the data address? Isn't this CharMaps: ? or Ascii_Set: ? 

 

If so then why do you reference CharMaps later?



[code]
READ --> from (charMaps+char)*8 into tmpByte2 
[/code]

You can't have a complex line in SX/B like this. 

Please explain a little bit more. 

Also was I supposed to use this within the SCROLL_LF routine as I previously posted OR is this it's own routine in place of it?

Is there anyway to do 5x7 characters instead of 8x8 (as I would rather use a dataset already made). If not ok, but just asking.

Sorry for all the questions. I just want to understand this clearly. 

Thanks so much!
