<HTML><BODY>Ok. nobody answered, so i do it myself. <br><br>so the problem was , that it is nowhere described how to controll continues servo (the 360-servo in which PWM controlls not angle, but speed and direction) with PDUINO.<br>as no one answered this post i suppose - nobody knows it, or doesn't care )) <br>Hans-Christoph Steiner (author of PDuino) wrote to me, that he is not working with arduino for a long time. <br>Here's what i had to find experimentally. <br><br>1) need to switch pin to servo-mode in pduino interface<br>2) after that you can use pduino's servo-slider to experimentally find the proportions in which your servo is controlled, but doing it slowly and gradually. <br>3) then most probably you will need to send to the [arduino] abstraction the analogue messages like [ analog 7 0.88 ( - in my case i use 7th pin to control the FS5103r speed and direction.. some of the values will mean STOP.. and higher and lower this value will mean forward and backward.. <br>4) and all the changes should be gradual, but not jumping values, because the jumpings are too fast for the comport - that was the reason of it's overloading.<br>5) this means, that if you will need to change speed - you will need to use [line] object and find the appropriate speed of the ramp experimentally. <br>6) in case of pduino it also means that you can't do a thing like: going one way with high speed <-> going back with high speed.. because you can't switch speed immidiatly and always need to go through a STOP-value .. don't know if it is common for the comport and all continues servos.. <br><br>thanks <br><br><br>Mon, 15 Sep 2014 06:19:06 +0400 от Фывапр Олджэвич <tofuckof@inbox.ru>:<br>
