The latest release of uLisp now provides support for reading and writing SD cards. This allows applications such as:
- Logging data to an SD card.
- Reading and processing data from an SD card.
- Reading uLisp programs from an SD card and adding them to the current workspace.
The main function for working with SD cards is with-sd-card. In addition, all the input and output functions in uLisp now take an additional optional stream parameter, so you can use the functions read, print, princ, prin1, terpri, read-line, read-byte, write-line, write-string, and write-byte to read from or write to SD cards.
