I've been playing around with PIC, programmable integrated circuit chips. In a book by Mike Predko, he has some samples interfacing a PIC to a R/C servo. According to Mike the servo specs say a pulse of 1.0 ms sends the servo to the right stop, a pulse of 1.5 ms centers it and 2.0 ms sends it to the left stop. My tests are different. 1.115 ms is centered and 0.8 is right stop and 1.5 is left stop, with these pulses going out every 18 ms.
Are there any servo experts who can explain this apparent contradiction. I'm pretty sure of my timing accuracy.
