I am trying to separate the Voltage and current value coming from serial port using VISA. But only first value is reading. What would be the error? This is my LabVIEW file This is my Arduino code void setup() { Serial.begin(115200); } void loop() { float voltage = analogRead(A0); float current = analogRead(A1); Serial.print(voltage); Serial.print(","); Serial.println(current); delay(100); }

LabVIEW

Read Multiple analogue data using VISA in Arduino

3 things for you:

1. Your format for the Scan From String is using a semicolon for the delimiter. It needs to be a comma.

2. Depending on when you happen to configure the port, it is possible you get a partial message on the first read. Add a VISA Read before your loop and ignore the data that comes out. This should synchronize your reading to the data frames from the Arduino.

3. You don't need a wait in the loop. The VISA Read will limit the loop rate.
