MMD and Alarm Clock by zuisti (a working Proteus hex project)

[zuisti]

I work continuously on my PIC18 MMD project, it is still under development,
so only a working hex Proteus project (zipped) and a screenshot is attached.
I've not built it, working only in ISIS.Try it out please.

The DSN has two sheets (display and proc) and some masking 'widgets' on the first.

Some features:

- a cheap and small 28pin PIC (18F2620)
- two-line led matrix display (2 x 12 x 8x8)
- vertical and horizontal scroll (mixed too)
- right-left scroll (also mixed)
- scroll by char or by pixel
- start-stop scrolling, on-the-fly scroll speed setting
- on-the-fly selectable mode and messages
- single step by char or by line (also to begin/end)
- also double size chars
- HW spi to loading the hc595s
- IT controlled key-read with IT debouncing
- IT controlled matrix line (row) timing (protected also by the watchdog timer)
- two user modifiable message, stored in Eeprom, max 2x511 (in ISIS 2x127) chars
- plus max 98 fixed (known at the compiling time) msg (max 623 chars/msg, sum max 50k)
- one fixed msg with an inserted running clock (now: msg 2)
- settable DS1307 rtc (hw I2C) and sw alarm (via rtc IT) with sound (hour:min:sec only)
- simple msg editor also via onboard buttons (if no rs232)
- flashing cursor in msg editor and clock/alarm set
- 7seg displays (mode, msg nr, ascii code of a char ...)

----- and yet what I think in future :-)

I know it is too much (:-), and the treatment is also not as simple,
(my goal was to test the basic routines), a realization is possible to simplify.

Hats off to you!!!

I am interested to see how proton looks like now after this interesting functionality :- )

[zuisti]

I've used  my PIC18 MMD circuit (see above)  to realize this simple animation display.

Using the MS Paint program I've generated 11 pcs (no patience to make more :-) simple
96x16 pixel BMP pictures for the 11 animation phase and I wrote a short program to display
them at 10 frame/second speed (the max speed may be 100 f/s at 4 MHz PIC clock).

A BMP is extracted to a 192 bytes long record, the program itself occupies only 232 bytes (!)
from the PIC's 64k flash so you can use max 340 frame pictures (ie a 34 seconds animation).

Attached a working Proteus hex project as a demo, maybe I use it for my new MultiLang project
(here I already wrote about it ) which is currently being prepared, like a power-on INTRO

Hi, very useful project. Maybe I would use cheap controllers for driving  2 or 4 matrices, and someone  CORTEX with SPI or I2C to manage all.

regards.

On request here is the full project (attached):

- all the Proton source
- a readme file to explain how to make an own animation
- a simple batch file to automatize the process (not the drawing :-)
- a simple console-only application to extract the BMP data bytes
   (written by me, it's using in the batch)

Just as many of my request is that if someone makes a nice animation (using this), you let us know.

zuisti's multi_lingual MMD, using my above circuit. A working Proteus project is attached.
Also a screenshot (how are displayed  the simplified Chinese chars).

For now only a rudimentary form, for example  rs232 control  is not possible yet .

I know, there are some character-picture errors (such as the gaps between them), but I have used the Windows Arial_MS_Unicode font without any changes. This font contains more than 38.000 characters ...

The wanted  texts are included in a unicode text file (with a few control character added), it can easily be rewritten (then recompile is needed, of course).

zuisti's PIC18 MMD project, now with source files also (as I promised).
Tried in Proteus only. Read more (and see a picture) in the post #1 in this topic.
