This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for SDHC/SDXC memory cards
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.
- SPI connection at ~25kHz
- Supports SDHC, SDXC cards
- Supports 3.3v or Low-voltage range cards
- Read/write 512-byte blocks
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM SPI engine
P2/SPIN2:

- Very early in development - may malfunction, or outright fail to build
- Currently developed with slow bytecode SPI engine, until reliability is established
