When starting PS2-Controller, Servos drift away

Now its finally time to ask a question and i hope someone will help me (worked on this for 3 days now). Just run into something mysterious. Powering on the BotBoarduino and SSC-32U is no deal. PS2 connection is done and on port 6,7,8,9 and i plugged a cable controller to prevent PS2 Wireless communication problems. When i put buttons on PS2 Controller the On-Board speaker makes a sounds. Connection to the SSC-32U is realised via TTL. The SSC-32U blinks a startup with both LED as normal, and follows up with only the green LED. If i check the Baud-rate it matches with the BotBoarduino ( 38400 in uploaded Sketch and red LED when check the ssc32-u baud button). Just to mention i possess two BotBoarduino and i have the same problem wth both of them. (Some other facts: All 3 Leds on Botboarduino are constantly flackering) and if i plug the PS2-Controller out the green LED from the SSC-32U is more blinking than constantly flackering.

Now to the Problem: If i press start on PS2 Controller, the 3 LEDS on Botboarduino switch to of. The LED from SSC-32U switches to off an all is freezy. No controll is possible and no sounds from the Speaker will appear. In addition to that, and that is maybe the most important fact, the Servos are slwoly drifting away?

If i powering the SSC-32U on the computer (a pain to make it work, but it work now) all is fine. I checked erverythin more than twice and made a video for you. Please help me, i am at the end of my knowledge. :frowning:

One last thing, i tried it with all Baud-rates that the SSC32-U supply. ( Modifying in Sketch) because i had the feeling that the problem is there. It will not work

Hi,

Lets start with some analysis of the situation:

  1. The BotBoarduino (manual) seems powered and wired properly. All jumpers seem OK. As for the 3 LEDs continuously blinking, it is related to the fact that they are on pins 7/8/9 and these are also used, by default, with the PS2 interface. If the LEDs bother you, you can simply remove the 3 jumpers near them to disconnect them from those output pins.

  2. The behavior in the video would most likely indicate a power issue. Please provide the following details:
    2)a) Picture(s) clearly showing the SSC-32U and its jumpers. Make sure the power connections are also visible. You can unplug the servomotor for this step, if the wire are too much in the way.
    2)b) What power source is used for the SSC-32U?
    2)c) What power source is used for the BotBoarduino?

  3. If you have a multimeter handy, can you check the power at the SSC-32U VS1 and BotBoarduino VL before and after you press START?

  4. After you press START, the buzzer beeps and the motors start moving. If you press START again, what happens? Does it beep again? Do the motor stop or continue moving? Something else?

Sincerely,
