Dual Servos with 08M

[quethe]

I was wondering if the 08M can run two servos in different positions at the same time, or if the internal timer will only allow one servo to be timed at a time.
Also, is there any conflicts with running the servo comand as well as serial in or out?
Thanks Much

Not tried the 08M but the 28X can certainly run 8 at the same time so I'd expect it to ne OK. Never tried it with serout. I'm sure there is something in the manual about which timed commands interact with each other.

I have got two servos working on an 08M in different direction and rotations on a camera controller i'm building (code with much help from hippy)
let me know if you want it and i'll post it

For one week from the last download my Justbasic GUI will be available from Upload'r for camera control.
It's set on COM2 @ n2400 you'll be able to change the code to suit your self if you download Justbasic.

My setup uses a Tx 433MHz to send commands.

Adjust servo min &amp; max to suit your own.

Please make the proper connections when interfacing with your PC. Don't forget if using 08/08M input 3 a diode is required.
