On pixel scroll you can't read what say, it is very fast.

Hi,
Thanks for your fast reply...
As I wrote please decrease the speed with the dipswitchs and/or with the clock...
I'm waiting for the result...

its nice programme.

please take a space with two font then it will clear.

at this setting

When i change the osc from 2Mhz to 4Mhz then the speed it is double again the faster speed it is not visible the message i will transfer to the real hardware to see how it works but before i do this, i see how the command 13 (enter) it is not clear the text.

Hi,
Thanks but you must decrease the speed !!! Set the PIC clock to 0.5Mhz or slower if needed, or (what is better) set the speed with the dipswitch slower please!
As I wrote the serial communication not working yet in this project.
But I think we will continue this talking in a PM or ...(you know my email address)
Thanks

Hi sohel,
Thanks for the info and for your idea!
What do you think about the inserted space, it is one pixel or one space (5 pixels) in its width?
I'll try it out (the one pixel space, it is possible with pixel scroll but not with char scroll), thanks again.

can't you post the zip file here instead of linking it to another site.

Zuisti, nice project.
By the way, instead of storing the hex of alphanumeric code which will consume big memory in PIC, How about using EEPROM instead? What do you think?
Because I am worried that storing in EEPROM will show significant loss of speed, since accessing to EEPROM not as fast as accessing to RAM.

Hi cowwyland,

@1:
The storing of the "hex of alphanumeric code" is verily a memory consuming thing beacuse we must store min 7 pattern bytes for every chars. The PIC's intern EEPROM is too small to do this, and an accessing of an extern EEPROM is really much slower as the intern flash memory.

@2:
The accessing of the intern EEPROM (to get a char) is really slower a bit as the RAM or Flash but this is negigible beside the other things what we must to do (seeking and get the pattern bytes of the char, shiftings ...)

My last project uses this method and a new algorithm. Look at my newer thread:
