BS2p and the HB-25

JerryB

Hi All,
I've been playing with the HB25. Using the BS2 it works just great. I have it hooked up to my BS2p right now and its not behaving as it should. I guess I have to adjust the timing of the pulsout instruction but haven't hit on the right combo yet.·Would someone look at this snippit of code·and tell me what values I should change for the BS2p to get the same results I get with the BS2? Thanks a lot....in the meantime I'll keep trying.

Syntax: PULSOUT Pin, Duration

Function
Generate a pulse on Pin with a width of Duration.

• Pin is a variable/constant/expression* (0 - 15) that specifies the I/O pin to use. This pin will be set to output mode.
• Duration is a variable/constant/expression* (0 - 65535) that specifies the duration of the pulse. The unit of time for Duration is described below.

1875 is the center value for the BS2p, not 750. Your range would no longer be 250 but rather 625. Take care.

Thanks Chris and PJ Allen
I just used PJ Allen's ref to calculate the center value of 1875. Fixing to try it right now.

And it works. Wonderful to have experts looking over my shoulder!
