| Abstract: | The signal generator also known as the signal source or oscillator,in the production practice and science and technology has a broad application.In this paper,in understanding 8086CPU chip,based on the 8086 application interface chip design a signal generator,according to an external 16-bit code,use of the square wave generator 8253 changes in the frequency of the frequency of the signal generator,with LED LED display the set given the frequency of flashing,and then use the logical switch frequency changes. |
| Keywords: | signal generator MCU parallel input/output interface chip 8255 chip |
