In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Forrest wrote: The BS2SX is basicly a simple computer - it has 16K of EEPROM, a 5V voltage regulator and a serial interface circuit. So you could run it on a 9V battery and interface it to a PC's serial port using just a cable and (2) capacitors. The SX28 is just a microprocessor - you'll need to attach a voltage regulator circuit, and depending on the application a serial interface circuit and external memory to store data to use it. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=96593#m96607 Need assistance?
