This is a list of features that users have been requesting or that would generally be nice to have. However these are things that I don't have the time to implement or personally have no use of and therefore low motivation to invest too much of my time.

If you have a nice feature request or a solution, or if you have even worked on one of these issues, please do not hesitate to contact me.

Multiple sensors (for cadence, e.g.)

Problem: The Palm PDA has only one serial transceiver (UART) that can be internally wired (configured) to the IR transceiver unit or the RS232 level shifter. So it's either IR or RS232, but not both at the same time.

Suggestion I: We could of course use some other signal line of the wired interface, e.g., the HotSync button line. It triggers a hardware interrupt, too. For this to work, the internals of the software (interrupt handling) would have to be changed. Drawback of this solution would be that it's only possible with the wired (VAIF-1) interface, not with the infrared variant (VAIF-2).

Suggestion II: Another – more complex – solution would be to involve some small microcontroller that could be hooked to a whole bunch of sensors (of any sort) and communicates to the Palm via RS232 or even IR (real data transfer). Drawback of this solution is – of course – that users would have to have such a programmed microcontroller or even a complete interface (small box).
