here are the pictures they are not the best :laughing:

If you have researched on this forum at all then you already know the first direction you are going to get is to separate the VL from the VS supplies by removing the VL=VS jumpers and powering the VL inputs from 9V batteries using the clips supplied with the boards. Failing to do this it is not readily possible to distinguish a wiring problem from a power problem.

Hey David,

PowerPod needs to know if you are using the Bot Board, or the Bot Board II. This will change where the PS2 controller and the SSC-32 data connections are. Are you sure you used the Boat Board II config selection.

Also what sort of battery are you using, it’s not in the pictures.

We are assuming you have created the program correctly with PowerPod and have programmed the chip successfully with the IDE. Even if the PS2 controller were not connected the robot should stand up when powered on. You say it will not stand up. Two thing can cause this.

  1. The battery is too weak.

To fix this you need to charge the battery. Connect it to the bot and turn it on. Look at the green LED on the SSC-32. It should light up, then go out, then blink twice. At the same time the robot legs should move horizontally, then lift the body up, then stay there. This will happen even with the PS2 receiver unplugged from the robot.

  1. the Bot Board II is not talking to the SSC-32 properly.

This can be tested by turning the robot on and looking at the SSC-32 green LED. if it lights up, but never goes out, it means the Bot Board is not talking to the SSC-32.

yes i have selected the bot board II configuration
i am use this battery “Akkupack 6.0V Ni-MH 2800mAh”
my battery is full loaded
i turned it on and i saw that the light on the ssc-32 is shining all the time
it does not go out

So at this point we know for sure the SSC-32 is not getting any commands from the Bot Board. This can also be caused if the I/O pin was damaged. Try moving it to another pin, then change the program to reflect this change.

;-------------Constants ;PS2 Controller / BotBoard II (PS2 controller => pin 12, 13, 14, 15) DAT con P12 CMD con P13 SEL con P14 CLK con P15 ;*** SSC-32 card communication on pin 8 *** SSC32 con p8

Change the SSC32 con P8 to SSC32 con P10 and move the plug from pin 8 to pin 10. See if the LED goes out now.

hi thanks it works I can control it :smiley:
it is at pin 10
why it has not worked on Pin 8 i could program it but not steer :confused:

The fast answer is there appears to be something wrong with the I/O pin 8 on your atom. The long answer would go into detail as to how an I/O pin can be damaged. It’s not terribly difficult to blow an I/O pin. make it a high and accidentally short it to ground for a few micro seconds… Oh, are you sure that pin didn’t get bent under when installing the chip into the Bot Board II? I’m glad you’ve got it going! Great job!

no there was nothing bent down
i dont know what was happend
the most important for me is that it works :smiley:
