随着集成芯片价格的不断下降,现在的单片机爱好者越来越多了。许多人采用的是PC机加编程卡的方式进行编程,就是在PC里面进行8051程序的设计,然后用编程卡将程序写入单片机芯片,再把芯片插入用户电路运行,如果发现错误就再写,再试。象这样开发一个程序,可能要反复往芯片里写一、二十次甚至更多,而且有些问题如果不知道具体的故障点是很难排除的。根据我们的经验,一般的89C51芯片使用廉价的编程卡只能写
With the continuous decline in the price of integrated chips, and now more and more single-chip enthusiasts. Many people use the PC programming card programming, which is 8051 in the PC program design, and then use the programming card to write the program into the microcontroller chip, then the chip into the user circuit to run, if you find errors to write Try again. Develop a program like this, may want to write repeatedly to the chip one or twenty times or more, and some problems if you do not know the specific point of failure is difficult to rule out. According to our experience, the average 89C51 chip can only write using cheap programming card
