Merge with old features.

[radical-las]

Hi! PxMatrix used to support more various LED matrix, there was support of more mux_patterns and scan_patterns. I've attached version of PxMatrix.h, that supports all features.

PxMatrix.zip

Example of cuted-out code:

// Specify how the Panel handles row muxing:
// BINARY: Pins A-E map to rows 1-32 via binary decoding (default)
// STRAIGHT: Pins A-D are directly mapped to rows 1-4
// SHIFTREG: A, B, C on Panel are connected to a shift register Clock, /Enable, Data
// SHIFTREG_ABC_BIN_DE: A-C are connected to Shift-Register Clock, Data, /Enable, D-E to binary decoder (crazy shit)
// SHIFTREG_SPI_SE: Like SHIFTREG, but you connect A and C on Panel to its Clock and Data output (and ground B). This will not work with fast_update enabled!
enum mux_patterns {BINARY, STRAIGHT, SHIFTREG_ABC, SHIFTREG_SPI_SE, SHIFTREG_ABC_BIN_DE};

// This is how the scanning is implemented. LINE just scans it left to right,
// ZIGZAG jumps 4 rows after every byte, ZAGGII alse revereses every second byte
enum scan_patterns {LINE, ZIGZAG, ZZAGG, ZAGGIZ, WZAGZIG, VZAG, ZAGZIG, WZAGZIG2, ZZIAGG};
