How to use?
Connect the 7003-assy using default pins or choose your own, then try the examples.

TCC7003.h - Library for TCC 7003 display assembly Created by Lucas Volwater, July 2021 based on hardware description and example code from Aart Schipper
10x 9443 display module
Logic board:
34_pin | function | register function |
---|---|---|
1,2,3,4 | V+ | |
5 | D0 | display A0 |
6 | D1 | display A1 |
7 | D2 | odd or !even column |
8 | D3 | A0 row |
9 | D4 | A1 row |
10 | D5 | A2 row |
11 | D6 | Display A2 |
12 | D7 | EN or !EN module via ST2, pos 1 is !EN ( ? - klopt dit ?) |
17 | !EN | module via ST2 |
20 | !EN | module via ST2, pos 1 Tied to GND on header. |
19 | !WR | display |
15 | LE | latch register |
31,32 | GND |
if no pins are given as arguments, these are the defaults:
- D0 on pin 0, D1 on pin 1, D2 on pin 2, etc. up to D7 on pin 7,
- EN unused (wire to GND)
- LE on pin 8
- WR on pin 9
Otherwise alternatives can be given in this order: (D0,D1,D2,D3,D4,D5,D6,D7,LE,WR,EN).
- So that would be for example TCC7003 led_display(0,1,2,3,4,5,6,7,8,9,13); to use pin 13 as enble.
What's with all the !EN lines?###
If you want to use multiple displays on 1 bus: The jumpers ST1 and ST2 can be used to select which of the 3 !EN lines activates the display. !EN lines are active low. (So it is like SPI "chip select".)
