3. C Library Functions (For use with the Serial/SPE Environment)

The following is a list of the library functions available to use with the 4D Systems C Serial Library, which is a

generic C library which can be ported to run on the Raspberry Pi. The C Serial library is compatible with the

display module supplied with this Pack when the display module is configured with the Serial Environment

from the Workshop4 IDE. This listing below is not relevant if using the ViSi-Genie Environment.

For detailed information on each of these functions, please refer to the ‘Picaso Serial Command Set Reference

Manual’ Document, available from the Workshop 4 product page on the 4D Systems website,
