is31fl3741-spin

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the IS31FL3741 LED matrix driver.

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

Salient Features

  • I2C connection at up to 400kHz

Requirements

P1/SPIN1:

  • spin-standard-library
  • 1 extra core/cog for the PASM I2C engine

P2/SPIN2:

  • p2-spin-standard-library

Compiler Compatibility

  • P1/SPIN1 OpenSpin (bytecode): OK, tested with 1.00.81
  • P1/SPIN1 FlexSpin (bytecode): OK, tested with 5.9.7-beta
  • P1/SPIN1 FlexSpin (native): OK, tested with 5.9.7-beta
  • P2/SPIN2 FlexSpin (nu-code): FTBFS, tested with 5.9.7-beta
  • P2/SPIN2 FlexSpin (native): OK, tested with 5.9.7-beta (not yet implemented)
  • BST (incompatible - no preprocessor)
  • Propeller Tool (incompatible - no preprocessor)
  • PNut (incompatible - no preprocessor)

Limitations

  • Very early in development - may malfunction, or outright fail to build
  • Not optimized
  • API not yet finalized
  • The only layout tested is with the Adafruit PN 5201 panel. Other modules that use the IS3741 may have a different LED matrix layout vs the chip's memory, so the display may look incorrect on them.
