Hi again...

Regarding the position reporting provides by PSC, can anyone helps me to make a code so that i can increase the servo position by step of 20 (just an example) from its current position, whenever it is at that time...

I tried to use the command report position, '!SCRSP', and the input receive are
x y z(where x is the channel number, and z:y is the value reported)...
so if i interested to increase the current position to 20, should i make the code like
position = buff(1) + buff(2) + 20
·(by using·the same variables use in the PSC documentation)

Adding the bytes won't increase the position by 20.· One is the lowbyte and the other is the highbyte.· The highbyte value should be multiplied * 256 before being added to the lowbyte and then to the offset to get the correct value.
