I know that they are nominally 1 to 2 ms long but do some R/C controllers, for whatever reason, produce pulse widths outside this range? I guess from the fact that you only have inputs from 0 to 208 that the R/C controllers never produce pulse widths outside this range. But have you actually checked that this is the case. I am interested in what you have to say on this because as soon as I have my 16F84 programmer ready I want to try building an R/C speed controller. BTW, Did anyone else almost faint at the size of yesterday's PICLIST digest? I was glad when I found that half of those 3580 lines were taken up with encoded attachments and not reading material.
