Programming system and programming method thereof

Abstract

The invention discloses a programming system and a programming method thereof. The system comprises a programmer / PC, a transfer plate and at least one transmit plate, wherein level conversion circuits are arranged on the transfer plate and the transmit plate; the programmer is connected with the transfer plate; the transfer plate and the transmit plate are in communication connection through an RS-485 bus; the transmit plate is connected with a target chip in a one-to-one corresponding way; the transfer plate, the RS-485 bus and the transmit plate form a communication path. The method comprises the following steps: converting a target program into a binary BIN file; converting the binary BIN file into data meeting an IPS protocol; sending control signals through the communication path and controlling the target chip into an IPS download mode; sending a synchronization frame to the target chip through the programmer from the communication path to perform synchronization; reading the model and sector of the target chip through the programmer / PC after synchronization, and writing the model and sector into a program. The system has the advantages that off-line programming can be realized, one-to-multiple parallel programming can be realized, the programming efficiency is improved, and the system cost is low.

Description

technical field [0001] The invention relates to a burning system and a burning method thereof. Background technique [0002] The programmer is a tool for writing data on integrated circuits that can be written into programs. It is mainly used for writing programs in chips such as single-chip microcomputers (including embedded) / memory (including BIOS), and can be divided into various functions in terms of functions. Type programmer, mass production type burner, special type burner. [0003] Existing mass-produced burners are usually connected to a burner through a computer. A software runs in the computer to control burning and open the program file to be burned, and then transmits data to the burner through USB or serial port. The input device is then transmitted to the target chip. The existing programming methods have the following disadvantages: (1) online programming must be done with a computer, and offline programming cannot be realized; (2) only one target chip can ...

AI Technical Summary

Problems solved by technology

The existing programming methods have the following disadvantages: (1) online programming must be done with a computer, and offline programming cannot be realized; (2) only one target chip can be programmed at a time or multiple target chips can only be connected in series Burning, serial programming is to burn each target chip in turn, the burning time is still the sum of the burning time of all target chips, it is impossible to achieve parallel programming of multiple target chips, and the burning efficiency is low
