Here's a huge secret, DJ's method above is how I manage to look like I know what I'm doing 99% of the time!

Rich you're too modest... I would say more like 99.9%

@ Dave - Thank You for the credit.

:P @DJ, your a scream!; "calmly following these steps". "Calmly" is my middle name.

Your right though. I could have probably found the answer to this question if I had just slowed down and re-read the spec sheet. I do get in a hurry at times. It usually results in a flash and smoke. eek

Also this is not for displays. I'm trying to set up a two way serial connection between EZB V4 and a Kangaroo / Sabertooth. I need the Roo to tell me where it is after I send a serial command to move to a set position.

Lol you indeed are one of the most patient people I've ever met. I write for the masses, knowing that future readers will stumble across my posts. Never think I'm directing anything at any specific someone. It's always generic.

Much like how I explain where the learn button is. Of course you all know. But someone new may not know... So I be specific for the future

Dave, I referred to I2C port as I am still using a V3 so my PIC does the conversion from I2C to bi-directional comms to the serial port of the Kangaroo, hope this helps.

@Tony, each time you post it always a huge help. Thanks, the confusion was my fault not yours. When I thought it through I came to that conclusion.

Ok... I can't find any example using uart method, neither in local examples nor in the cloud... is it me or they all disappeared?

Some basic quesitons :

I'm trying to TX buffer values (between 0 and 640) from an arduino (running a code to read motors' encoders) to EZB UART0. I hooked arduino's tx to EZB's rx and arduino's rx to tx (although I only need to receive data from arduino, but in the doubt... not sure if they both need to be connected).

I tried these codes so far, without success :

UARTInit( 1, 0, 9600 )

$available = UARTAvailable( 1, 0 )

print($available)

UARTRead(0, 0,$available)

UARTReadBinary(0, 0, $available, $variab)

print($variab)

sleep(200)

halt() 

here is what I get :

Start
1: UARTInit( 1, 0, 9600 )
3: $available = UARTAvailable( 1, 0 )
5: print($available)
> 0
7: UARTRead(0, 0,$available)
9: UARTReadBinary(0, 0, $available, $variab)
11: print($variab)
> Error on line 11: Variable is an array: $variab
Done (00:00:00.1605282)

FYI if you type what the Script Help says about UartReadBinary() you get an error message :

UARTReadBinary(0, 0, UARTAvailable(0, 1), $variable)

here is what it returns :

16: UARTReadBinary(1, 0, UARTAvailable(0, 1), $variable)
> Error on line 16: Missing ) in Expression
Done (00:00:00.4367821)

that's why I used a variable for the UartAvailable() function, above. 

I'm desperately trying to get data returned. It works in the terminal EZB, I receive the counts from the encoders connected to the arduino. So, here is my real question (and since I couldn't find any example using UART keyword in the examples despite what was said earlier in this thread) :

How do I get to read what comes from this arduino the same way they are read and displayed in the serial terminal?

Thanks in advance
