In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Steel wrote: The Great thing about the SX is how simple it is to hook up. If you want to use an internal oscillator; You need a GND going to VSS. You need 3.3V-5V going to VDD. You will want to tie the RST pin to VDD (with a 10k resistor). You will want a 4 pin header that connects to OSC1, OSC2, VDD,VSS. If you look in the manual, there is a 'programming interface' picture that shows this. It is al you need. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=250467#m251245 Need assistance?
