| 中文摘要: |
| 给出系统以 ATMEL 公司的89C51为中央处理器,外扩8255可对多种可编程器件进行编程,并采用单+5V 电源的 RS232电平转换芯片 MAX232完成与 PC 机通讯,本系统还采用电子开关去调整 VPP 电压及信号线以适应不同型号的可编程器件。 |
| 英文摘要: |
| A programmer presented in this paper,which is able to program several types of PLD,can be used to debug the MPU applied system together with the software of MPU simulation.In its design,the 89C51 (ATMEL Co.) is used as CPU extended by 8255(INTEL Co.),the MAX232A as series port to communicate with PC and use electronic switch is used to change the voltage of Vpp and lines of singles m order to fit the different types of PLD. |
