I'm thinking about buying the comprehensive frameset...

What I _would_ have bought if they were cheaper:
- USB2Dynamixel
- Additionnal servos, to make a real waist

Yes, I would have bought USB2Dynamixel too if it were cheaper

And the wireless Zig if it needn't be soldered!

We do have a USB-serial adapter in stock for 9gbp.

http://robosavvy.com/store/product_info ... cts_id/370

It is based on the FTDI FT232RL chip.
http://www.ftdichip.com/Products/FT232R.htm

Code: Select all
# Support for bus powered, self powered, and high-power bus powered USB configurations.
# Integrated 3.3V level converter for USB I/O .
# Integrated level converter on UART and CBUS for interfacing to 5V - 1.8V Logic.
# True 5V / 3.3V / 2.8V / 1.8V CMOS drive output and TTL input.


If the output voltage of the FT232RL is 5V compatible with the AVR chips, then this module can be used to communicate with the AX12 bus (by shorting the Rx and Tx lines..).
Jon, can you tell if this chip will work ?

The chip itself will work, but unfortunately you need a tristate buffer and an inverter in addition. Those parts are less than a dollar each, so you can put together something pretty easily using it, and if anyone wants, I can post part numbers and a wiring schematic...

Note that in addition to Rx and Tx you also need access to the CBUS2 pin, which is pin 13 on the 28-pin SSOP package chip.

The ATmega series micro-controllers can talk directly to the bus without requiring the buffering hardware, because you can enable/disable Tx and Rx individually under program control.

Don't try shorting the Tx and Rx pins on the FT232 - it will probably fry the chip...

Thanks, Jon. My "electronic skills" are very basic, but if you post it I will study it :)
