In SX Microcontrollers, SX/B Compiler and SX-Key Tool, JonnyMac wrote: The RATE parameter of INTERRUPT is a compiler directive; it is used at compilation, not run time. You can manipulate the ISR rate by changing the RETURNINT value -- but it's only eight bits (the RTC roles over from 255 to 0 and triggers the interrupt). Also, when your running an interrupt you can't use SERIN unless the interrupt timing has been accounted for with the EffectiveHz parameter (see the help file under FREQ directive). ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=206420#m206421 Need assistance?
