Problems solved by technology

The program memory can be a read-only memory or a flash memory. At present, flash memory is widely used. The existing programming software burns the code to a location of the flash during programming. It is easy to be damaged in a harsh environment, and the yield rate of the built-in flash memory is an important factor that directly affects the yield rate of the MCU

Abstract

The invention discloses a microcontroller and a code programming method for the microcontroller, including: a communication interface for communicating with an external processing unit; a first program storage unit for storing running code files; A program storage unit is used to store the same code file as the above code file; a program storage control unit is used to control the connection of the communication interface with the first program storage unit or with the second program storage unit. The invention realizes automatic switching to the second program storage unit when the first program storage unit is damaged, thereby reducing the defective rate of the MCU chip. Through one-time programming, a spare second program storage unit is formed. When the first program storage unit is broken, it does not need to be reprogrammed, which reduces the number of times of programming.

Description

Technical field [0001] The present invention relates to the field of Internet technologies, particularly to a method of programming a microcontroller, and the code for the microcontroller. Background technique [0002] MCU (Microcontroller Unit; MCU), also known as one-chip microcomputer or microcontroller, a central processor to make the appropriate frequency and size reduction, and the memory, a counter, USB, A / D conversion, UART, PLC, DMA and other peripheral interfaces, even LCD driver circuit are integrated on a single chip including a chip-level computer, make different combinations for different control applications. Such as mobile phone, PC peripherals, remote controls, automotive electronics, industrial stepper motor on the machine arm control, MCU can be seen in the figure. MCU comprises a built-in program memory for storing a program executed by MCU. The program memory may be a read-only memory may be a flash memory, flash memory applications currently very broad, co...
