Hi All,
I have a staubli RX90 robot with a cs7 controller which i can control via putty.
Now my professor has asked to see if it is possible to control this with an arduino uno and max232.
I have tried the basic sketch here http://www.arduino.cc/en/Tutorial/SoftwareSerialExample But i am not getting any joy
Am I missing something simple
You'll want to use the hardware serial on the Uno since the software serial library reportedly maxes out at 19200.
If you do use the hardware serial, you need to disconnect your CS7 from the Arduino when you are uploading a sketch and connect it back afterwards.
If this sounds like a hassle you might want to opt for the Mega 2560 with its 4 hardware serial ports.
