Some of you might know that i am building a hexapod as i seeked help several times. Its now just a matter of hours before i receive the Axon II microcontroller and the Xbee Starter Kit. As i am new to robotics i know little about it. This is why i want you guys to check if the follwing connections are right.
First of all i'd like to know if this is right:
1) I have 18 servo motors (Like the one in the picture below). Is it correct if i connect them to the pins (G5-B7 & H7-L0) in the Axon II. Sample servo connected is shown below on pin B4.
2) The battery connection shown below.
3) Shown also is an Xbee Explorer Regulated. Can i the connect it to any of the pins (L1-L7). Below, its connected to pin L1 for power and to UART (U0) for T&R.
Note: The blue dots in the picture are used to show the end points of each line.
One thing i'd like to ask about also is:
I found this information in the Axon II datasheet:Hardware PWM
Hardware PWM is perfect for creating a perfect high frequency squarewave without any cost to the processor. Servos using hardware PWM can only be used on 16 bit pins, while regular DC motors can be used on any PWM pin.
8-bit timer pins: G5 (T0), H6/B4 (T2)
16-bit timer pins: B5/B6/B7 (T1), E3/E4/E5 (T3), H3/H4/H5 (T4), L3/L4/L5 (T5).
Do my servos use PWM ? If yes, then does this mean that i can only connect them to the 16-bit timer pins (Only 12 of them) ? What are the timer pins used for? Do I need them for the hexapod project ?
