Meanwhile - on request - prepared some simplified versions of
my PIC16 MMD (its source is
here).
My own
keyboard routines is also used if needed (but without any IT).
There are five variants (look at the attached pictures):
Amsg auto rotating short fix msgs, no scrolling
selectable (re)start-msg and rotating time
quasi unlimited nr of msgs (max len: 1000)
140 (max 170) Hz refresh rate at 4 MHz clock
2msg two static selectable msgs (max len: 1000)
scrolled or center aligned
SW brightness equalization, each matrix row get same "switched on" time
Appr 100 Hz refresh rate at 4 MHz clock
Mmsg a lot of selectable msgs (by stepping), 2 power-on starting msgs
scrolled or center aligned
SW brightness equalization
quasi unlimited nr of msgs (max len: 1000)
Appr 100 Hz refresh rate at 4 MHz clock
Xmsg 6 selectable msgs (but 7 during power-on), (max len: 1000)
scrolled or center aligned
SW brightness equalization
easily expandable up to 15 msgs
Appr 100 Hz refresh rate at 4 MHz clock
XFmsg the same as Xmsg but wait (no display, a led blinks) until release key(s)
All variants above are easily supplemented with a PC serial control (rx-tx).
The projects (full with source) are uploaded for all beloved Sonsivri members (link attached).
Merry Christmas and Happy New Year
