use labview

As a separate check to ensure the program is working, we will use the PicoScope to check the messages being sent. Connect up channel one of the PicoScope with the probe attached to the RX of the Arduino and the ground of the cable to the ground of the Arduino. In the PicoScope software select Serial Decoding and then RS232/UART. Select Data A (all other default settings are what we need) and then in Graph Display and Table Display select ASCII/Hex (you can select decimal if you wish and look up the values in the ASCII table). Compare this with example trace given in figure 1, can you decode this value manually? You will need to be able to manually decode in the NUMBAS demo exam question but for now we will utilise the PicoScope software to do this for us. Using your initials (only 2 characters, for example I would use JH), enter these characters as your Command signal and check the returned signal is what you would expect (both in Labview and on the PicoScope). Take a screenshot to capture all of this data (Labview Front Panel and PicoScope display) together with team member names. Each team member should use their own initials for their screenshot( use JP). Does the oscilloscope trace correspond to the expected message being sent? If not try these two things: Add a numeric indicator to the return count wire of the receiver icon in Labview. Try using the Serial.write command rather than the Serial.println command in the Arduino program.

take a screenshot and explain what the PicoScope trace is showing you about the transmitted message
