11.output devices
making board
I choose servo motor. In reference to a sample of Neil, the regulator changed which we have. And output pin changed from 6 to 7. I checked my board carefully. I wrote the sample firm using software pwm. but,motor didn't work. (fail again!!)
debug
mio-san checked by oscilloscope,and PWM square wave was output correctly. I tried change the C code, or tied battery to the direct motor, but these idea didn't work.
follow-up
I noticed that I made a easy mistake later.I change the fuse , then it did work!!!
