Controlling a motor from the CM-5 BUS

2010-06-08T14:33:36+01:00

Hi,

I was hoping to make it myself, would an analogue switch like these http://ie.farnell.com/nxp/74hc4066n/74h ... tt=380-957 be of any use.

I'm sorry if these are stupid questions, I'm still trying to figure out how it all works.

Controlling a motor from the CM-5 BUS

The easiest thing to do is to buy one of my I/O boards.

If you want to do it yourself, using a PIC, you'll have a bit more trouble. A PIC cannot individually switch on/off the Tx/Rx sides of the hardware UART, so you can't use the Tx/Rx short technique that I use on all of my Bioloid bus devices (using an AVR). You will have to use some kind of buffer and/or bus switch to interface to the bus.

Controlling a motor from the CM-5 BUS

2010-06-08T12:41:30+01:00

Hello All,

I am trying to figure out a way of controlling some normal motors from the CM-5 main controller. I've been looking around the forum and there seems to be solutions using an atmega for controlling servos as can be seen here http://robosavvy.com/forum/viewtopic.ph ... =interface .

I have recently taken an interest in PIC microcontrollers and I was hoping there would be a simple way of controlling a simple motor using the BUS on the CM-5 and a PIC 16f627.

Could anyone tell me if this is even possible or if they know of anywhere I could get information on what it would take to create this device?

Thanks in advance,
Ozirock
