Psion Development

EPOC 16: SIBO C SDK

As a full time job, I used to program Psion hardware (Psion HC) for vertical market applications in Vending Route Management and Inventory Control. Currently I work in other areas but do consulting work in Psion development in technical areas, largely in C and often in RS-232 serial communications. Please contact me if you need a Psion expert for a project, as a consultant, developer or mentorship program.

Since 1992, I've also been programming the Series 3 range in C using most of the development options available. Here are some links and code which should help people:

• Programmers' Question Time
• An EPOC 16 DYL for CRC-16 and CCITT-CRC
• Known Bugs and Workarounds
• Some useful Psion OOP Techniques and classes
• Undo/Redo
• Psion Series 3a Mouse Driver 0.6
• ISAM Database - some versatile utility routines
• Data compression routines - including a system usable with ISAM functions
• A portable C++ version of Psion's ISAM database manager
• Barcoding
• Serial Communications
