need help with HB-25 to propeller
llj
Posts: 2
I am not able to get the HB-25 to work consistantly with the propeller.
I'm stumped! This is what I did...
1st day hooked up signal and signal gnd to a RC reciever.......... no results
then tried sending 1ms pulse from propeller ................ no results
2nd day tried sending a string of 1ms pulses from prop ............ runs but wont start every time
3rd day tried to convert bs1 sample program to prop .............. no results
The fact that it worked one day but not the others is what is confusing me.
Is the prop chip able to drive the HB-25 directly?

Normally, the Propeller is TTL compatible for output and mus be able to drive the HB-25 directly. I suppose that the HB-25 need same signal as a servo ?
You can try object for drive servo from 'Propeller Object Exchange' like 'Servo32_Demo V1.2' or 'Servo-4'. Just for be sure that the code is right.
Best regards,

I did get things working tonight by toggling the comunication time out mode.
Neither unit worked before, but now both do. Who knows why but I'll take it.
