General development experiment board for single chip microcomputer based on CPLD (complex programmable logic device) or FPGA (field programmable gata array)

Abstract

The invention discloses a general development experiment board for single chip microcomputer based on CPLD (complex programmable logic device) or FPGA (field programmable gata array), which comprises an integrated circuit locking seat for locking the single chip microcomputer, a reset jumper, a jumper combination, a programmable logic chip, a downloading module for the programmable logic chip, a function model, a power module, a reset circuit for the single chip microcomputer and a downloading module for the single chip microcomputer. The power module is used for providing power for the whole development board; the reset lines for the reset circuit and the downloading module of the single chip microcomputer are electrically connected to the pins of the integrated circuit locking seat via the reset jumper; the programmable logic chip is electrically connected with the integrated circuit locking seat via the jumper combination; said downloading module and said function module for the programmable logic chip and the signal lines of the downloading module of the single chip microcomputer are electrically connected to the programmable logic chip. With the invention, the signal transmission among each function module and single chip microcomputer with different models can be processed flexibly; as a result, the invention can reach the purpose that single chip microcomputers of different models can be generally used by sharing one board and all the function modules can be also multiplexed by sharing one board.

Description

Technical field [0001] The invention relates to a single-chip microcomputer development board, in particular to a single-chip microcomputer universal development experiment board based on CPLD or FPGA. Background technique [0002] At present, the single-chip microcomputer is currently the most widely used central processing unit (CPU). Because of its low price, powerful functions, and simple use, it has maintained a strong vitality since its mass use in the 1990s. For users, in order to learn and use single-chip microcomputers, the most common method is to buy a single-chip microcomputer development board, learn hardware and software technology from it, and lay the foundation for research and development. You can also test hardware and debug software on the development board, but you cannot debug the hardware. Therefore, the MCU development board came into being. [0003] For intermediate and senior developers and scientific researchers, in the pre-research and development stage ...
