For example, when i send 'Backspace' this is the output: Bac kspace But on the arduino serial monitor it works fine. I made this script but it has a problem: procedure TForm1.ApdComPort1TriggerAvail(CP: TObject Count: Word) var msg:string I:word C:ansichar begin msg:= ' for I:= 1 to count do begin C:= apdComPort1.GetChar if C = #7 = false then begin if C in then begin msg:= msg + C end end end (msg) msg:= ' end The problem is that the 'count' isn't right. I want to read a string from my Arduino via Usb(Serial). The Delphi application I wrote to test the PC-to-Arduino communication is very.Ĭonversely, anything received on the virtual RX is sent out over the hardware TX. The second PC connected to the Arduino via the second PC's serial port. Using the COM port Bi-directional Communications.

This example uses 5 LEDs that will be controlled from the Delphi program via serial communication. Arduino IDE provides a simple serial port monitor that we can use to send. Serial Communication Between Two Arduinosīeginning with Arduino, Part 7: Serial Communication.The virtual RX pin is set up to listen for anything coming in on via the main serial line, and to then echo that data out the virtual TX line. In the example below, digital pins 10 and 11 on your Arduino or Genuino boards are used as virtual RX and TX serial lines. This can be extremely helpful when the need arises to communicate with two serial enabled devices, or to talk with just one device while leaving the main serial port open for debugging purpose. Software Serial > SoftwareSerialExample Software Serial Example Arduino and Genuino boards have built in support for serial communication on pins 0 and 1, but what if you need more serial ports? The has been developed to allow serial communication to take place on the other digital pins of your boards, using software to replicate the functionality of the hardwired RX and TX lines.
