Palm SV203 Serial Control Library was designed to send commands and receive analog-to-digital sensor input from a Pontech SV203 microcontroller board. It consists of one class and several support files. It has functions to control all servo functions (absolute move, incremental move, zero pulse, direct digital pin set/clear/toggle) and analog-to-digital sensor inputs. There is also a test program which utilizes most/all functionality of the library; it can be run standalone on the Palm to test an SV203 board.
PalmOrb is software that allows you to use your PalmOS device as an LCD status display for your computer. You can display system stats (such as CPU load graphs, CPU temperatures, free disk space), news alerts, stock indexes, WinAmp graphs, etc. It works by pretending to be (or emulating) a real LCD (a Matrix Orbital LK204-25). You can use existing software that expects a Matrix Orbital display.
