| This HP 15c program implements an N-point forward Discrete Fourier Transform for any real-valued sequence in Matrix A. This relatively small program is for anyone who is in dire need of calculating the Forward DFT of a real-valued sequence with no computer or advanced calculator in sight. This software can run with the HP15c CE in default mode (20-point DFT max) or 15.2 mode (52-point DFT max). The zip file contains a flashable .bin file plus plain-text program listings in common formats (.15c, .jrn, etc.) Full documentation (with instructions, sanity-check example, comments, per-instruction stack state, and execution timing tables) is included as well. |
HP50GPS is a set of programs designed to capture, display and save GPS data on the HP50g calculator via the serial port. The programs are written in User RPL and System RPL and require an NMEA 2.2 complaint serial GPS unit and a serial cable. An SD card is required to save collected GPS data. Code was developed and tested using the cable available at the commerce site of hpcalc.org. Package includes binary program files, plain-text source code and user's guide.
