Support for original Hardware using Arduino ICM7218 Library

[DirtBagXon]

Arduino ICM7218 Libraries available

Using the ICM7218 Library libraries for the Arduino it may be possible to support the Cinematronics original scoreboard which used the ICM7218 LED driver.

Development would require access to original scoreboard hardware.

Mode requirement:

ICM7218::CODEB - Supports 0-9, H, E, L, P, - (hyphen), ' ' (space), plus . decimal point (default mode).

CODEB is the original hardware mode it would appear. However, it would require readdressing the 7-bit ASCII A character (switched P and H flicker) in sae on the Arduino side.

ICM7218::DIRECT - Direct control of LED segments. Each bit represents one LED segment plus the decimal point.

In DIRECT mode, the char* is a sequence of bit-mapped bytes corresponding to specific display segments. This may be more appropriate.

Random erratica

• mode pin is floating in original schematic
• ICM7218 myLED(ID0, ID1, ID2, ID3, ID4, ID5, ID6, ID7, mode, write, chip_cd)

Constructor for the C or D versions of the chip. Has one additional parameter, which can be any 8-bit value (this parameter is used to differentiate between the two constructors, but the actual value passed is not used by the library).
