In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Zoot wrote: What Bean said :-) Read the help file under directives -- it explains this very clearly. The SX documentation itself has suggested OSC settings and parallel resistor values for most available resonator, crystal and ttl clock values. Reading over the directive documentation (fuse settings) is a must. The fuse bits determine how your SX is actually setup and running (clock freq, brownout, oscillator settings, etc) , and are arguably the most important settings on the device -- the rest is all code and can be changed at runtime. Thanks Bean for mentioning the OSC setting, which I neglected. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=404051#m408644 Need assistance?
