![]() If ((scaleOutput.indexOf(".") = 8) || (scaleOutput.indexOf('. ![]() The SCI is more widely used than the SPI, and can communicate over longer distances. The RS-232 interface to the Dragon-12 board, for instance, uses an SCI interface. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. The Serial Communications Interface (SCI) module is a relatively slow, asynchronous communication port that is widely used to communicate with other embedded systems and devices. ![]() Serial.println(scaleOutput.indexOf(".")) On computers, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. By definition, UART is a hardware communication protocol that uses asynchronous serial communication with configurable speed. Electrical signaling is balanced, and multipoint systems are supported. Serial.println("IF I PRESS PRINT ON MY SCALE") RS-485, also known as TIA-485 (-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. String scaleOutput = mySerial.readStringUntil("\r") The mbed Microcontroller can communicate with a host PC through a USB Virtual Serial Port over the same USB cable that is. To use shift registers in serial communication, we need two of them. Serial.println("IF I SEND A COMMAND ON SERIAL MONITOR") How do we communicate data between computers, or between peripherals and the CPU. The manual of the scale can be found here: #include I think it might be a terminator issue? Please find my code below and advise. 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. I need to read weight values form a digital balance (A&D FX-120i).
