Serial.println(scaleOutput.indexOf('.')) So whats this serial communication Its an asynchronous communication protocol where two devices exchange data serially, as in one bit at a time, using two. Serial.println('IF I PRESS PRINT ON MY SCALE') String scaleOutput = mySerial.readStringUntil(' ') Serial.println('IF I SEND A COMMAND ON SERIAL MONITOR') Commonly associated with RS232 and TTL serial, it enables Arduino and other microcontrollers to communicate with your computer or other serial devices. In this chapter, not only will the common methods of transmitting data be reviewed (RS232 and USB), but in addition some useful coding. Serial communication is a way for data transmission over long distances.

#Serial communication manual#

The manual of the scale can be found here: #include There are a wide variety of serial communications protocols available, but all rely on some form of coding scheme to efficiently and effectively transmit the serial data across the transmission medium. The data will be sent sequentially, one bit at a time (1 byte 8 bits), contrary to parallel. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. Serial communication is simply a way to transfer data.

I think it might be a terminator issue? Please find my code below and advise. On computers, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. Once I connect the Uno to the scale, using software serial and a ttl to RS232 shield I can receive data send from the scale to the Uno but once I send commands to the scale from to Uno no feedback is received. If I connect my Uno to the computer via the USB to RS232 converter I can send command from the Uno to the PC and receive data from the PC, monitored via serial monitor. If I connect the scale directly to my computer via a USB to RS232 converter the computer can send commands to the scale and the scale returns the weight. STEP 1: START SERIAL COMMUNICATION USING Serial.begin(). It is important to match the right protocol with the right application. Serial communication using arduino board is quite simple and easy. There are a very large number of different standards and protocols for serial communication, ranging from the very simple to the seriously complicated. There are many serial protocols, but in this course we will show you one of the first and simplest protocols that transmit one bit at a time. I need to read weight values form a digital balance (A&D FX-120i). There are two broad types of serial communication: synchronous and asynchronous. Serial communication is prevalent in both the computer industry in general and the embedded industry in specific.
