Resolved by DJ Sures!
I've been trying to receive data through the Uart port in EZB V4 and use it in a script. I've successfully been sending special commands to move my motor to exact points through a Kangaroo/Sabertooth combination and that's working great. I've even been able to read how many Bytes are in the buffer useing the below Script. This Script successfully moves my motor to position 113261 at Speed 10000 and returns a reading of 5000 bytes on the debug screen of the script. However I get no info at all when I look at the UARTRead line. Even is I did I don't know how to convert that info into any useful command in my script.
Kangaroo X2 Commands:
P = Postion as read from an encoder on the motor.
S = Speed the Kangaroo lets the Sabertooth move the motor at.
Getp = Command to tell the Kangaroo to send the position it us reading from the encoder at any given moment.
0x0d = Carrage return Code:
$Getp = "Getp"
uartWrite(1, 0, "1, p113261 s10000", 0x0d)
sleep(3000)
uartWrite(1, 0, "1, Getp", 0x0d)
Sleep(3000)
$x = UartAvailable(0, 0)
print("Bytes in buffer: " + $x)
$Getp = UARTRead(0, 0, $x)
print("Received: " + $Getp)
Basically I want to move my motor to a point and be able to trigger an event or another script before the motor gets there. I know I need a loop that reads the "Getp" info returned from the Kangaroo X2 but I cant find the right code to retrieve it through the Uart port and also be able to use it.
Any help with this code is welcomed. 
2) How many bytes does $x equal?
3) Have you looked at $Getp in the Variable Watcher?
$x equals 5000 bytes in the debug screen of the script window when the Print command is used.
No I haven't looked at the Variable watcher for the Getp. I'll have a look. Should that give me a hint?
Thanks for the tips so far.
Thanks for the suggestion. I haven't tried that yet but would need to learn how it works before I do so. I'll give it a go tonight. I did have the ARC Serial port working with the old V3 but had no feedback option.
I am able to see that there's 5KB bytes in the buffer. I think that's the max receive buffer of these UART ports. Do you think there could there be more bytes than this buffer can handle?
I've very new to UART ports and how to use them.
Check the parameters for the UARTAvailable() and UARTRead() vs UARTWrite() that you used
As for examples, please check the examples folder in ARC for the UART example project.
Now I get the proper position readout of p113261 . Here's what shows in the script console (Second line from the bottom):
Code:
Thanks so much, I've been stumbling over this all evening. Couldn't have done it without you! Now I think I can finish developing the script.
Glad to hear it's good!
