specific Embodiment approach 1

[0013] Specific implementation mode 1, a method for upgrading a dual-chip system instrument single-chip microcomputer in this implementation mode, the method is as follows:

[0014] Step 1. The main chip reads the upgrade package into the internal storage of the meter;

[0015] Step 2, analyze the upgrade package, obtain the single-chip microcomputer upgrade program, compress the single-chip microcomputer upgrade program and divide it into multi-segment data packets;

[0016] Step 3: The main chip sends the multi-segment data packets to the single-chip microcomputer in order to complete the upgrade of the single-chip microcomputer.

[0017] Specifically, the present invention is mainly aimed at the full liquid crystal instrument of the two-chip system, and requires that the main chip should be able to run an operating system and mount a USB.

[0018] like figure 1 As shown, the main chip is used to read the upgrade package into the internal storage via USB, and the main chip...

Abstract

The invention relates to a single-chip microcomputer upgrading method, in particular to a method for upgrading a single-chip microcomputer of a double-chip system instrument, and aims at solving the problems that an existing method for upgrading the single-chip microcomputer of the double-chip system instrument is poor in stability, low in speed and complex in upgrading operation. The method comprises the following steps: step 1, enabling the main chip to read an upgrade package into an internal memory of the instrument; step 2, analyzing the upgrade package to obtain a single-chip microcomputer upgrade program, compressing the single-chip microcomputer upgrade program and dividing the single-chip microcomputer upgrade program into multiple segments of data packages; and step 3, enabling the main chip o sends the multiple segments of data packages to the single-chip microcomputer in sequence to complete upgrading of the single-chip microcomputer.

Description

technical field [0001] The invention relates to a method for upgrading a single-chip microcomputer, in particular to a method for upgrading a single-chip microcomputer in a double chip used in an instrument. Background technique [0002] Due to the needs of fast response and low power consumption in standby mode, the current full LCD instrument adopts a dual-chip architecture, that is, a main chip is used to run the operating system and boot program, and a low-cost single-chip microcomputer is used to realize power management, CAN network communication, etc. Function. After the instrument is sold to the customer, the manufacturer needs to maintain and upgrade the product. The traditional method is to upgrade through the CAN network, but this method has poor stability, slow speed, cumbersome upgrade operation, and requires professional equipment support, which is not very friendly to customers. Contents of the invention [0003] The object of the present invention is to p...
