We are currently trying to send a string through LabView to our Arduino Uno for lights. We already have the Arduino code written, but our strings are not sending through LabView. We are testing it with the transmit and receive lines jumpered to an adapter and fed into another computer to read the string using HyperTerminal. We are not getting any string to leave the LabView code. Please help us as soon as you can. A screenshot will be included of our current LabView code regarding this issue. If you would like to see our string, I can post that in a reply.
VISA: the resource is valid, but VISA cannot access it.
Is a common error when another program or systems on a PC or roboRIO has already taken control of the serial port and there fore blocking your program access to it.
Just came across that last night and that’s exactly what’s required for RS-232 to work. We then got a strange error on the DS about the IMU but it appears to be working still as does the RS-232 now. We’ll keep monitoring. Thank you.
