i bought 2 hitec servos HS-422,and I would test them before modifying them
i made a test program ,but it doesn't work as it should
i generated a 2 ms width pulse,repeated every 20 ms during 1 second, then a tempo of 2 seconds,then a 1.5ms width pulse,repeated every 20 ms during 1 second,i did the same with a 1 ms width pulse
with this program ,i think it should turn,wait 2 seconds,come back wait 2 seconds,then turn the other sens.
well ,IT DOES NOT !!!
sometimes ,it doesn't move at all,sometimes it moves really really slowly (just like a stepper)
so ,i wish somebody could help me,tell me what i have to check,or a mistake with the program .......... please
PS : i do the tests in educational board,with a an old computer power supply,the microcontroler is a Pic16f877a,i use mikroC for prgramming
