In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Coriolis wrote: The biggest complaint I have seen from stamp users about the BS platform are 1) no interrupts and 2) single threaded. While the SX isn't multithreaded, use of ISR in such a fast processor can make it appear as if it is multithreaded. The single most asked question is generating servo pulses for more than one servo simultaneously, something that is very difficult in a stamp. Bean's 16 channel PWM/servo controller in the Projects forum is an excellent basis to show this functionality. Jon's Midi receiver (also in the project forum) is a good example how processes can occur in the background (receiving midi commands in his project). A program to show the usefulness of the speed of the SX processor is Jon's [url=http://forums.parallax.com/forums/default.aspx?f=7&m=56682][color=green>[u]encoder project[/u][/url],] I tried to find a good example of interrupts in the SX, but the closest I could find was Peter Van der Zee's [url=http://www.parallax.com/sx/contest/contest_rtos.asp][u]Preemptive RTOS[/u][/color][/url]. But this was written in assembler and uses the RTCC interupt rather than an example of an external interrupt system I was looking for. BTW, its an honor to have such an esteemed author as an active member of the forums. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=84834#m84837 Need assistance?
