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".)
