Problems with a usb PSC and a BS2P40

My project uses a BS2p-40 and I have had no problem with using AUXIO so far, but I am unable to get my USB PSC to work within it's test program.

Both power sources are ok. The serial wire from my project is connected to Aux·pin 2. All 16 of the servo conections power up and holds a servo in place. There is a RED led and a flashing GREEN led. But there is no indication that the BS2p-40 program ever starts to loop.

thanks Bill

The "set buadrate" test works fine

    I removed the P-40 and installed it in my PDB, set the serial I/O to pin 0 and it still doesn't work. The first 2 demo programs in the Serial PSC pdf work fine, but none of the programs to actually operate a servo work.

    Capt. Quirk,

    I believe that the value for·your Baud constant for 2400 baud, in your servo·test2.bsp file, is incorrect.

    Your value of 396 is for a BS2 and not a BS2p.

    The value for 2400 baud for a BS2p is 1021.

    Just a thought.

    Regards,
