The codes of the single chip microcomputer are generally written by a computer, but the codes of the single chip microcomputer can only be operated in the single chip microcomputer, so that the problem of how to lead the codes of the single chip microcomputer stored in the computer into the single chip microcomputer occurs, and for the AT89S51 single chip microcomputer, the traditional method is completed by a special device called a programmer. The specific method comprises the following steps: firstly, placing a singlechip on a programmer, connecting the programmer with a computer, and programming singlechip codes in the computer into the singlechip through the computer and programs on the programmer; then the singlechip is taken out of the programmer and installed in an actual circuit board operation program, and the functions of data acquisition, display, various controls and the like of the singlechip are realized.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can be at system programming's singlechip circuit board, aim at solving prior art, during singlechip application development, need additionally to configure the problem that the programmer wrote into program code.
The utility model discloses a realize like this, can be at the singlechip circuit board of system programming, including main singlechip and programming singlechip, the programming singlechip passes through the data line with the computer and is connected, and receives the singlechip program code that sends from the computer, the programming singlechip is connected with main singlechip simultaneously, writes into the program code who receives in the Flash memory of main singlechip.
Furthermore, the programming singlechip and the main singlechip are positioned on the same plate body.
Furthermore, the programming single chip microcomputer is connected with the computer through a USB interface.
Furthermore, the programming singlechip is connected with the main singlechip through a toggle switch.
Furthermore, the base of the main single chip microcomputer is of a locking structure.
Compared with the prior art, the utility model provides a can utilize the program code in the programming singlechip can the direct receipt computer at system programming's singlechip circuit board to, in the programming singlechip can write in the program code of receipt into main singlechip, like this, then do not need extra programmer, realized writing in the program code of main singlechip, made things convenient for main singlechip's procedure modification, perfect and upgrading greatly, simultaneously, reduced development cost.
