specific Embodiment approach 1

[0037] Specific implementation mode one: combine figure 1 Describe this embodiment, an online parallel programming system described in this embodiment, the system includes an acquisition module, an address configuration module, a transmission rate setting module, a timing module, a file comparison module, an optimization module and a programming processing module ,

[0038] The identification module is used to identify the voltage quantity generated after being connected with the adapter;

[0039] The address configuration module is used to configure the initial address and program transmission channel with the same number of voltages, and send each initial address to the data buffer area in the corresponding microcontroller through the program transmission channel;

[0040] The transmission rate setting module is used to set the transmission rate for each program transmission channel;

[0041] Timing module, used for setting transmission time for each program transmission c...

specific Embodiment approach 2

[0047]Embodiment 2: This embodiment is an online parallel programming system described in Embodiment 1. The data buffer area is used to store program code files or optimized program code files and old firmware. When the chip is powered on Or when receiving a reset signal, check the old firmware. After the check is passed, set the jump flag to check whether there is an upgrade flag. If yes, enter the download area to analyze the new firmware in the download area. Compression algorithm and solution difference algorithm, modify and overwrite old firmware, set the jump flag, run the application, if not, do not upgrade.

[0048] In addition to being able to burn programs, the data buffer area of ​​the present application can also store old firmware, so as to upgrade the single-chip microcomputer.

specific Embodiment approach 3

[0049] Embodiment 3: This embodiment is an online parallel programming system described in Embodiment 1. The system also includes a switching power supply,

[0050] The switching power supply is set between each microcontroller and the adapter,

[0051] The switching power supply has a voltage feedback mechanism inside. When the detected input voltage is lower than the preset low voltage, the internal switching chip increases the output duty cycle or frequency to make the voltage value of the input voltage reach the preset voltage. When the input voltage is higher than the preset When the high voltage is set, the internal switch chip reduces the output duty cycle or frequency, so that the voltage value of the input voltage reaches the preset voltage, thereby inputting a stable voltage for each microcontroller.

[0052] In this embodiment, a switching power supply is used to ensure the voltage stability of the single-chip microcomputer, so as to avoid the termination of program...

Abstract

An online parallel programming system and a programming method belong to the field of single-chip microcomputers. The purpose of the invention is to solve the problems of uncontrollable programming speed and poor programming stability in existing programming methods. This application sets the initial address for each chip, so that the program code files can be transmitted to the single-chip data buffer area corresponding to the initial address in time, so that each single-chip can burn the program stably. It is used for burning program.

Description

technical field [0001] The invention relates to a programming method and belongs to the field of single-chip microcomputers. Background technique [0002] Most of the existing single-chip programming methods are for single-chip single-chip programming, while the method for multi-block single-chip programming is mostly used on industrial production chips. Before the chips are soldered to the circuit board, use a special programmer to program After programming, solder them to the circuit board in batches. Multiple chips can be programmed at the same time. Generally, home appliances with large output will use this method for programming. This method belongs to the hardware programming method and cannot be used for software programming. upgrades. And this method is not suitable for programming a small number of chips. [0003] The existing online programming is to directly program the chip on the circuit board, which does not depend on the programming socket and is not affecte...
