This is a P8X32A/Propeller driver object for 23xxxx-series SRAM
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 20MHz W / 10MHz R (P1), up to 20MHz W / 20MHz R (P2)
- Operations for reading and writing a single byte, up to a 32-byte page, or multiple bytes across page boundaries
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM SPI engine
- memory.common.spinh (provided by spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- memory.common.spin2h (provided by p2-spin-standard-library)
| Processor | Language | Compiler | Backend | Status |
|---|---|---|---|---|
| P1 | SPIN1 | FlexSpin (6.1.1) | Bytecode | OK |
| P1 | SPIN1 | FlexSpin (6.1.1) | Native/PASM | OK |
| P2 | SPIN2 | FlexSpin (6.1.1) | NuCode | Not yet implemented |

(other versions or toolchains not listed are not supported, and may or may not work)
- Very early in development - may malfunction or outright fail to build
- Single-lane SPI only (i.e., no DSPI, QSPI)
- Tested only with Microchip 23LC1024 (may work with similar ONSemi and ISSI parts)
- Tested only with 1Mbit/128kbyte part
