2550 with OOPics was created by Darrell
Has anyone successfully used an OOPic with this controller? I have an OOPic-R and I'm beginning to think another controller may be easier as I've yet to get this to work. Granted, I've not had a ton of time but the two just aren't talking. Anyone with positive experience here would be appreciated.

<P style="MARGIN: 0px">We've had good luck with the BS2SX in our high school group.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">The command is:
<P style="MARGIN: 0px">SEROUT SPin, Bmode, ["!", RFWD, HEX2 127. CR ]
<P style="MARGIN: 0px">where
<P style="MARGIN: 0px">SPin = 16
<P style="MARGIN: 0px">Bmode = 24816 9600 baud, 7 bit, even polarity, inverted
<P style="MARGIN: 0px">RFWD = "B" can be a, A, b, B for motor selection and speed
<P style="MARGIN: 0px">and the 127 is the speed with 0 = stop and 127 = full speed
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">Of course you must send new commands at least every second to keep the watch dog chained.
