The PicoPAK-VIII Servo Coprocessor
| Have you ever wanted to control an RC servo,
but you couldn't devote enough processing time to repetitively generate the
required pulses? The PicoPAK-VIII is the perfect way to solve this problem.
This diminutive 8 pin IC monitors an output from a host computer (e.g., a
Basic Stamp, a PIC, or other microcontroller). When it senses a pulse, it
repeats the pulse to the servo with a 20mS space between pulses. It will
continue to output the pulse until the host sets another pulse output. That means your servo code can stay almost exactly the same, but you don't have to service the servos except when you want to change their position. Here's a simple Basic Stamp program that sets a 2mS pulse output and then stops: '{$STAMP BS2}
'{$PBASIC 2.5}
PicoPAK pin 15
HIGH PicoPAK
PULSOUT PicoPAK,1000 ' 2uS/ count so 2mS
GOTO stopp
' Stop here, but don’t let Stamp
' reset
STOPP: GOTO stopp
Of course, a real program would do something other than stop, but the point is that the Stamp doesn't have to intervene -- the PicoPAK continues to generate pulses. |
