Self-made project: Parallel port to SPI adapter
The goal of this project initiated by Niklas Ekström is to develop a cheap and easy to build SPI adapter that can be connected to the parallel port of an Amiga. In addition, the performance of the adapter should be as fast as possible.
There exists many SPI peripherals that can be connected to this adapter. The SPI adapter comes with a source code library, spi-lib, that is used to perform reads and writes to the SPI peripheral. For each kind of SPI peripheral, however, a separate driver needs to be written that uses spi-lib, and exposes the functionality of the SPI peripheral to the operating system using some suitable interface.
In the directory examples/spisd an example of how an SD card module can be connected to the SPI adapter, and a driver is provided that lets AmigaOS mount the SPI card as a file system.
Version 2.1, released yesterday, fixes a bug in the SD card device driver of version v2.0, which did not work correctly with the Amiga 3000 or 4000. (dr)
