这是一个电话拨号防盗报警器的单片机控制程序（C语言）。电话拨号防盗报警器由单片机、键盘输入、数码管显示、触发电路、拨号电路等组成。单片机负责控制检测输入输出、模拟摘机、拨号报警、挂机等一系列的程序动作。单片机型号为AT89C2051。(This is a burglar alarm dial microcontroller control program (C language). Dial burglar alarm from the microcontroller, keyboard input, digital display, trigger circuit, dial-up circuit. SCM controls the test input and output, analog hook, dial-up alarm, the program hang up and a series of actions. MCU models for the AT89C2051.)

能实现对方波频率进行采集，能够采集低频到100K左右的方波(It can collect square wave frequencies from low frequency to about 100K.)

stm32f4 adc 的代码，双通道，用DMA保存数据。(stm32f4 family c code, adc This example provides a short description of how to use the ADC peripheral to convert a regular channel in Dual interleaved mode using DMA in mode 3 with 5Msps. DMA mode 3 is used in interleaved mode in 6-bit and 8-bit resolutions. The Dual interleaved delay is configured 6 ADC clk cycles. On each DMA request (two data items are available) two bytes representing two ADC-converted data items are transferred as a half word. The data transfer order is similar to that of the DMA mode 2. A DMA request is generated each time 2 data items are available 1st request: ADC_CDR[15:0] = (ADC2_DR[7:0] << 8) | ADC1_DR[7:0] 2nd request: ADC_CDR[15:0] = (ADC2_DR[7:0] << 8) | ADC1_DR[7:0] The ADC1 and ADC2 are configured to convert ADC Channel 12, with conversion triggered by software. By this way, ADC channel 12 is converted each 6 cycles. In this example, the system clock is 168MHz, APB2 =84MHz and ADC clock = APB2 /2. Since ADCCLK=)
