基于AT89S52和MAX038的程控信号发生器的设计 Mechanical and electrical engineering in 2008, 37 (10) mechanical and electrical engineering in 2008, 37 (10) figure 1 signal generator hardware design block diagram based on AT89S52 devices and the design of the programmable signal generator MAX038 Xiong Chunru, ju-fang hu, guo-bing huang (at the college of mechanical and automation engineering, jiangxi at 338031) abstract date: 2008-04-23 abstract: the design based on MCU AT89S52 and MAX038 signal generator, frequency and amplitude can be used to produce programmable sine wave, square wave and triangular wave signal. MAX038 function generator with a small amount of peripheral device responsible for generating waveform, the waveform after LM6361 broadband power amplifier circuit output voltage amplification and level. The main controller AT89S52 is responsible for the selection of waveform, frequency modulation, output amplitude modulation, LCD display, keyboard operation, etc. Key words: signal generator; AT89S52 ; MAX038 Chinese library classification number: TN741 literature identification code: B article number: 1009-9492 10-0069-041 (2008) introduction MAXIM MAX038 chip is produced by our company A high-frequency, precise function generator, which only requires less connection The outside device can produce 0.1 Hz ~ 20MHz. The highest A trig of a 40MHz The sawtooth wave, the sine wave, The square wave is affected by the pulse wave and the frequency and the control of the air ratio Im going to do [1] independently. It can be achieved by controlling MAX038 and other unit circuits by single chip AT89S52 Control the type, frequency, output magnitude of the waveform, etc. This changes the lack of manual regulation of traditional signal generators Points. 2 signal generator hardware circuit design 2.1 hardware circuit block diagram whole circuit mainly by AT89S52 singlechip machine And people Machine interface (LCD and keyboard), power circuit, Waveform generation and control circuit (sig
