Next to the last card reading, you need to make a weighbridge read.
The following figure shows how to read the lbs.
The weighbridge always sends data to the serial port
LabVIEW PC and serial communication, labview Serial CommunicationOrigin
When I was a freshman, the school opened a public elective course called LabVIEW programming. At that time, I certainly didn't know what LabVIEW was, but I still chose it. The instructor is an associate professor at the School of mechanical engineering. He showed us several projects using Lab
The RS232 interface is a standard for serial communication jointly developed by the American Association of Electronic Industry (EIA) and bell system, modulation regulator manufacturers and computer terminal manufacturers in 1970.
Its full name is "Technical Standard for Serial Binary data exchange interfaces between data terminal devices (DTE) and data
.
● After the data is sent and received, the host sends a Checksum, Which is compared with the checksum of the data received from the slave. If the checksum is the same, it indicates that the data is sent correctly and then exits the program; if the verification and sending are incorrect, the data will be resent.4. Specific implementation
The serial port has a very important register:
SM2 is a multi-host
PHP sends text via serial port, PHP sends text via serial port
As technology advances, the TEXT message sending and receiving field has successively produced three modes: block mode, text mode based on AT command, and pdu mode Based on AT command. Text mode is relatively simple, and multiple Nokia mobile phones support

Perform the following operations on a 64-bit win8 system:
1. code compilation
Two Connection library files, rxtxSerial. dll and rxtxParallel. dll, must be downloaded for serial
accept, at this time two serial port is closed, click on the right of the "open" button, open COM2 and COM3 serial port, start communication.
In the COM2 port, enter "123456789A" in the Send field, and then click Send, in the rec
Currently, the commonly used serial ports include 9-pin serial ports (DB9) and 25-pin serial ports (DB25). When the communication distance is close (1. Description of common signal ports of DB9 and DB259-pin serial port (DB9) 25-p

microcomputer temperature information collected by a series of oral to the computer, the effect of such as.This is the simplest serial communication program is completed. You can see that it only needs to add a few lines of code, very simple.Part II:The previous section has introduced the implementation of the simplest serial receiver program writing, the follow
Learn VC serial port programming, understand the standard of serial protocol is necessary, in fact, the serial port relative to other interfaces (such as USB interface) is very simple.

can be executed to read data from the serial port. We transmit the temperature information of the MCU serial set to the computer through the serial port. The effect is as follows.
This completes the simplest serial
the program, you can read data from the serial port. We transmit the temperature information collected by the microcontroller from the serial port to the computer, as shown in figure.
This completes the simplest serial communication
In Win32, two programming methods can be used to implement serial communication. One is to use ActiveX controls. This method is simple but not flexible. The second is to call Windows API functions. This method can clearly master the serial communication mechanism and be free and flexible. This article only introduces t
Serial port is commonly used in the data transmission between the computer and the external serial device, because the serial communication is convenient and easy to use, so widely used. Now the international serial
