Detailed Description
Example 1
The present embodiment will be described in further detail with reference to examples and drawings, but the embodiment of the present embodiment is not limited thereto.
As shown in fig. 1-2, a multifunctional cascade manner implemented through a 485 bus comprises the following specific steps:
the embodiment consists of three parts, wherein one part is a 485 bus, and the 485 bus is used as a data exchange place of the scheme and is called as a 485 bus; secondly, PC end upper computer software is "positive point atom P100 off-line burner multifunctional cascade upper computer software V1.0", which is used as a main control unit of the scheme and is called "upper computer software"; thirdly, the positive point atom P100 off-line burner set to 485 slave mode is used as a controlled unit of the scheme and is called as an off-line burner.
The upper computer software used in the embodiment is written by using C# and runs on a Windows platform. The upper computer software realizes the three-point functions by calling a COM port to realize receiving and transmitting commands. The upper computer software is used for controlling the offline burner mounted on the cascade bus by sending instructions to the 485 bus, and mainly realizes the following three-point function:
(1) Triggering the off-line burner to burn the user data stored in the off-line burner into the target chip;
(2) Controlling an offline burner to burn data sent to a 485 bus by upper computer software into a target chip;
(3) The off-line burner is controlled to read data from the target chip and return the data to 485 bus for use by upper computer software;
the cascade bus is connected to the COM port of the PC to realize data exchange with the 485 bus, the offline burner triggering the specified ID can be selected to burn or all offline burners on the bus can be triggered to burn in the cascade function configuration and the execution operation type, and clicking the button for executing burning triggers the offline burner to execute one-time burning action according to the configuration.
When the 'burning parameter configuration- > only burning the internal mirror image of the offline burning device' is selected, and the off-line burning device is triggered to burn, the upper computer does not send a user-defined data burning related instruction to the 485 bus, and when the 'burning parameter configuration- > burning the internal mirror image of the offline burning device + the user-defined data' is selected, the user-defined data configured by the user is burned after the internal mirror image of the offline burning device is burnt. The configuration of the ' burning parameter configuration- > user-defined burning data burning configuration- > burning start address (Hex) is the start address of the data needing to be burnt by the offline burner to the target chip, the ' burning parameter configuration- > user-defined burning data burning configuration- > burning data source ' can select the source of the data needing to be burnt by the user in a cascading mode, the burning data has three sources, namely, the data is sourced from the data directly input by the user on the upper computer, the files added by the user are sourced from the user, and the user can select the data source according to the actual requirements.
The offline writer used in the embodiment is a positive atom P100 offline writer, and the offline writer has an offline writing function of storing the program file of the user and writing the program of the user into the chip. The offline burner is provided with a serial port UART which is led out for expansion use, so that the function of a 485 slave is realized by updating the code in the offline burner, and the external 485 transceiver can access a 485 bus.
The 485 bus adopts a half duplex working mode, supports multi-point data communication, adopts balanced transmission and differential reception, and therefore has the capacity of inhibiting common mode interference. In addition, the bus transceiver has high sensitivity and can detect voltages as low as 200mv, so that transmission signals can be recovered beyond kilometers, and a 485 bus is selected as the bus form of the embodiment. The 485 bus comprises a transmission cable and a plurality of 485 bus transceivers, the upper computer software converts a COM port signal selected on the PC into an RS485 signal to access the 485 bus through a USB converter designed on the basis of an FT232 chip at a USB port connection positive point atomic team of the PC to realize data exchange, and the offline burner accesses the 485 bus through a 485 transceiver module designed on the basis of the RS3485 chip to realize data exchange.
As shown in fig. 3, when the upper computer software needs to control the offline writer with the specified ID to perform writing, the upper computer sends a command for performing writing, which includes the ID, to the 485 bus through the 485 bus transceiver, the offline writer with the corresponding ID immediately replies a response signal after receiving the command, marks the local as busy state, then takes out the user firmware stored in the current offline writer to write into the target chip, and marks the local as idle after writing is completed. When the offline recorder executes recording, the upper computer software periodically transmits a command to inquire the state of the offline recorder with the specified ID, and when the state of the offline recorder is found to be idle, the recording is considered to be finished.
As shown in fig. 4, when the upper computer software needs to read the data in the chip connected with the offline writer with the specified ID, the upper computer software sends a command containing the ID and intended to read the data in a certain address range to the 485 bus, and the offline writer with the corresponding ID responds to the upper computer software within a limited time after receiving the command and returns the read data to the 485 bus.
As shown in fig. 5, when the upper computer software needs to write data into the chip connected with the offline writer with the specified ID, the upper computer software sends a command containing the ID to write a segment of data into a certain address range to the 485 bus, the offline writer with the corresponding ID immediately replies a response signal after receiving the command, marks the local as busy state, then writes the received data from the 485 bus into the target chip, marks the local as idle after completing the writing, and periodically sends a command to inquire the state of the offline writer with the specified ID when the offline writer executes the writing, and considers the writing to be ended when the writing state is found to be idle.
When the upper computer software needs to control the offline writers on the 485 bus to realize multi-path writing, the corresponding offline writers can synchronously start writing only by respectively sending the command which contains a plurality of offline writer IDs and is meant to execute writing to the 485 bus.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that several similar modifications and improvements can be made without departing from the inventive concept, and these should also be considered as being within the scope of the present invention.
