![]() ![]() Many of the issues discussed here are general, but I find that principles are best understood when backed up by examples of their application. However: Either device could be replaced by another. In the tutorials, the 'devices' are a Windows PC running programs written with Delphi and an. #ARDUINO DELPHI SERIAL COMMUNICATIONS HOW TO#If you have already read my page 'dt4r' (the illustrations just a little way down the page will be familiar), you can that isn't duplicated THERE! This is one of the more advanced tutorials in a series which shows you how to link two devices using serial comms. There are notes on some of those issues on, for those of you who need them. You can't just plug 'anything' into your computer or anything else! In particular, make sure that you aren't assuming that an RS-232 interface can be connected directly to, say, an or BASICstamp, or PIC or other. ![]() In particular, I disavow any responsibility for any consequences arising from connections you make between devices. I disavow any responsibility for things you may elect to do. #ARDUINO DELPHI SERIAL COMMUNICATIONS FULL#Using the COM port Bi-directional Communications 'Master'/'Slave' two computer system This has good information, and a search button at the bottom of the page Please don't dismiss it because it isn't full of graphics, scripts, cookies, etc! I am old fashioned. For information about uploading code to Arduino Board, Note: If it shows error while uploading code to Arduino, disconnect the connection between Arduino and try to upload program on it. ![]() You can transmit your data or variable like this. Hello will be transmitted from Sender Arduino to Receiver Arduino. All Arduino boards have at least one serial port (also known as a UART or USART): Serial. Used for communication between the Arduino board and a computer or other devices. Mitov Software - Delphi Arduino control and communication Boian Mitov – Mitov Software Thursday, J. Make a circuit as per the given diagram after uploading code. For more information about serial.read, Step 4: Upload the code to Arduino Upload the code to the sender and receiver Arduino Board. In loop, received the data from sender Arduino using Serial.readBytes. In setup, the Serial Monitor is begun at 9600 Baud. First, initialized a blank string to store serially received data. For more information about Serial.write, Step 3: Code for Receiver Arduino This is code for Receiver Arduino Board. In loop, sent the data to receiver Arduino using Serial.write. First, initialized a string with data 'Hello'. Circuit for Serial communication between two Arduino Boards Step 2: Code for Sender Arduino This is code for Sender Arduino Board. ![]()
