Hi all,
This's a asembly code to built a SSC(Serial servo contorller), probably a stupid question,as i don't understand how it work.

VB controller
schematic
I had tried,but just only adjust 0 to 126 ,and 127 to 255 can't apply accuracy pulses.
Now, hope to solved the problem,
I tested for the assembly code on an AT90S8515 at 3.6864 MHz. The code was compiled with AVR Studio 4.12 SP3.
Run the Visual Basic program (EXE file) and move the Scroll Bar I get this pulse width:
Beginning,Pulse width = 2285 μs (2.285 ms) ,It's OK.
Press the cnter button(value 127): Pulse width = 1595 μs (1.595 ms),It's OK.
but move button down to value 128 and down to value 254,the Pulse width = 0.905 ms and no change.
Press the cnter button(value 127): Pulse width = 1595 μs (1.595 ms),
Move button up to value 126 and up to value 0, It worked fine .
The problem is why I moved button down to value 128 and down to value 254,the Pulse width = 0.905 ms and no change.
Hope somebody tried successful and help me to use the applications.
Thanks a lot.
Best regards
