[0044] Specific examples:
[0045] The present invention mainly adopts STM32F103xx series single-chip microcomputer and ENC28J60 Ethernet control chip to design a method with BootLoader function and remote firmware update through a network interface, and its design principle and implementation process are described in detail.
[0046] Take advantage of the STM32F103xx series microcontroller self-reading and writing on-chip program space characteristics, first write the BootLoader program in the on-chip Flash, and then use the BootLoader program to erase and write the on-chip user program of the single-chip microcomputer, without the traditional emulator and JTAG interface Ways to do programming work.
[0047] STM32F103xx series microcontrollers are based on the ARMCortex-M3 core and are designed for high-performance, low-cost, and low-power embedded applications. It has a clock frequency of up to 72MHz, on-chip integrated 32-512KB Flash memory, which can be used to store programs an...
