Serial RS-232• Needs extra hardware at the remote end• Basic Stamp II or other microcontroller• Performs intensive I/O tasks without affecting CPU• There are only a small number of serial ports• Use USB interfaces - kernel maps to standard /dev» FTDI FT8U232AM/BM chips» Keyspan series converters• Don’t bother with PCMCIA, not enough slots and fragile56 Wayne Piekarski Wearable Computer Lab CIS @ UniSA http://www.tinmith.net/lca2005lca 2005
Dumb controller boxes• You can buy boxes that have a number of input andoutput pins connected via USB, serial, parallel• These devices have no smarts and must be controlledcontinuously and will use up a lot of CPU time• Try to use a microcontroller if you can• MCU provides real time functionality and only makes theCPU deal with it when something interesting happens• I used this in my glove controller very successfully57 Wayne Piekarski Wearable Computer Lab CIS @ UniSA http://www.tinmith.net/lca2005lca 2005
