I am working on a 6 axis stepper signal generator (Step and Direction) and I have tried a few different ways but I can't seem to get the max freq that I am looking to be close to (1Mhz).
I am using the LPC1343
I am just looking for advice on the fastest way to do it.
My current idea is to use the 2 32bit timers with 3 match registers on each timer, but I would have to use a free running timer and do a matchReg++ on each interrupt and a position++ for each interrupt.
When the match is in toggle mode, how long does it toggle for?
I have also tried a version that uses Bresenham formula and one timer, but this one could not interpolate all 6 axis faster then about 200khz...
So I am looking to have all 6 axis running at a max of 1MHz and I am not sure of the best way to do this and if it would work with the 2 timers and 6 match registers...
Thanks
Dave
