It works the same as with a BS2, the difference is that the BS1 uses 10 uS units (2 on the BS2) -- for example:

и PULSOUT 0, 150иииииии ' stop
и PULSOUT 0, 100иииииии ' full speed
и PULSOUT 0, 200иииииии ' full speed -- other direction

are you sure Jon if its 150, 100 and 200 and not 150, 140 and 160.
Do let me know if I am wrong.

Those are the values for the "standard" values of 1.0, 1.5, and 2.0 milliseconds. What's important to understand is that for the BS1, the PULSOUT parameter is:

pulse_width (in microseconds) / 10.

thanks for the reply jon

i still trying to cut&paste a program together for a mini boe-bot using bs1 dx and bumper switches.

also i got a servo program running on the bs1 it will run a parallax c/r servo but not

my moded GWS pico servo but the GWS works fine in boe-bot?
