Building a Custom Portable Program
Creating and Setting Up the Upload Data Nodes
The last frame, Upload Data, allows the user to copy collected data from the portable’s file to a file on the PC. You will set up nodes that do the following:
•Display a menu asking if the user wants to upload data.
•If the response is Yes (<F3>), send data over the serial connector to the PC. If the response is No (<F4>), exit to the Main Menu.
•If the output is successful, display a message indicating so for 45 sec- onds (or until the user presses a key), and then clear the portable’s file and return to the Main Menu. If the output is unsuccessful, beep and display an error message, and then redisplay the prompt.
Create nodes for the Upload Data frame by completing the following steps:
