Scale_Simulator

Mock a scale via COM-Port (Arduino)

A simple simulator to test COM-Port applications. Several things can be setup on the device, like:

• 12 different Modes
• Min./Max. values
• No. of decimal places
• Baudrate, Parity, ect.
• Delimeter
• Start-/Endchar

Hardware

• Arduino Duemilanove
• LCD Keypad Shield

Libraries

• LiquidCrystal
• SimpleUI16x2
• EEPROM

Menu

UP & Down: changes the value.

Select: Confirms the current menu entry or sends the command

Left: Go back

• Listen (Waits for command)
• Send (Shows last command to send)
  • S
  • SI
  • ... (See Commands below)
• Setup
  • Values
    • Min. places
    • Max. places
    • Min. dec. places
    • Max. dec. places
  • Line End
    • None
    • CarriageReturn
    • Linefeed
    • CR+LF
    • LF+CR
  • Start/End
    • None
    • STX / ETX
    • < / >
  • Delimiter
    • . (Dot)
    • , (Comma)
  • Com-Port Baud
  • Com-Port Setup
    • 5N1 - 8O2 Serial
  • Send Bytedelay
    • Maximum random number between sending single bytes (0 = Off/send all at once)

Commands

• S, SI, SIR, SR, SX, SXI, SXI, RN, RM, FP0, GB1, P, FP
• D -> Prints everything followed on the display (DHello World!)
