Hi Everybody,

I was wondering if one of you had already experienced running 2 BasicAtomPro in // in order to get more power?
If it's possible I would like to have some help to try it myself.

Thanks

Hello, Chris.
By "//" I believe this means "in parallel"? How do you mean? One is master, the other a slave? They share a common job, but over two devices? The possibilities are endless, methinks.
You'll want to be more specific about what you want to do in the end.
Take care.

Hi Kenji,

Yes, exactly what you said, common job over 2 devices with one master and the other a slave.
My idea is to run a robot with 2 basic atom pro but I don't know where to start. What would be the best way to communicate between them in order to have one sending task to be done by the other one and getting feed back once it's done.
Can you help me on this?

Thanks

Hi Chris,

There are endless ways for you to do this, depending on your requirements...

Example Task: slave has 3 tasks that can be chosen by master and slave needs to tell master when done.
a) Could connect 4 IO pins between master and slave. On master side 3 are output, 1 input, on Slave side, 3 input, 1 output. When master wants slave to perform a task it raises the appropriate IO pin to high, which the slave sees and when it completes the task it raises it's output pin to high to acknowledge....
b) Like a could use 2 IO pins on master and master could choose which task by using the two IO pins as binary number...
c) Could use hardware serial port to communicate between the two, Master can send out packets with data telling slave what to do. Slave can send data back with information...
d) I2C - Could use I2C, but no slave I2c Support in basic, could probably set up hardware registers to do so...

I am using the 2 board concept in my robot. One board uses a Nano 18. Its purpose is to control a 1 pan and 1 pan and scan. One of the pan and scans has 3 sonars the other is used for video. I did it this way because it takes time to move the the servos and was easier to read the sonars. It also saved a birds nest in wiring

The main processor is a Nano 28x. It handles every thing else including wireless remote and autonomy. I use serial to comunicate.'

The nano18 board is custom. Right now I bread board the Nano 28x but I am about ready to order the board for the 28x.

Not hard to do>

Thanks Kurt for your advices.
Hi Jim, what you are doing looks like what I had in mind.
I am going to test hardware serial port to communicate. If I have a hard time doing it I will call you for help

Thanks again to both of you
