说明：  音量控制芯片，六通道音量控制芯片，可单独和全控。(The volume control chip)

stm32硬件SPI方式控制ADS1247采样驱动程序(stm32 hardware SPI driver controls the ADS1247 sampling)

自己调试的，stm32控制PCF8591输出电压程序，可用运算放大电路调整输出范围，可用于输出检测电压的设备。(Self debugging, STM32 control PCF8591 output voltage procedures, operational amplifier circuit can be used to adjust the output range, can be used to output voltage detection equipment.)

使用数码管和AT24C02实现： 1、数码管从0显示到99，溢出后从0循环显示，时间间隔为一秒。 2、显示到某个数时突然关闭电源，AT24C02将保存当前的数字。 3、重新启动后数码管会接着上次的数继续显示(Using digital tube and AT24C02 implementation: 1, the digital tube displays from 0 to 99. After overflow, it displays from 0 cycles, with a time interval of one second. 2, display a number of time to turn off the power suddenly, AT24C02 will save the current number. 3, after reboot, the number will continue to display.)

此程序和上一个程序是用于51单片机和430单片机的通信，通信方式为单工，430做主机51做从机(This program and a program for 51 And 430 single-chip communication, means of communication for the simplex, 430 to do Host 51 to do slave)

本人亲自编写的基于freescaleK60的ADC驱动，已经应用于我公司产品，请放心下载使用。(This c code is for freescale k60 mcu adc.)

stm32中，本例程实现通过串口输入不同的数字，串口打印出相应的字符串。(stm32, the present routine is accomplished by entering a different serial number, serial print out the corresponding string.)

基于STM32+ADS1232+keil温度压力采集(Temperature Pressure Acquisition Based STM32+ADS1232+keil)

这stm32f746描述了如何使用DAC外围 产生使用DMA控制器的信号。 在用户按键每按一下，信号已被选中，可监测 DAC通道： • 三角波形（通道1）。 -自动扶梯的波形（1频道）使用DMA传输。(This STM32F746 code provides a description of how to use the DAC peripheral to generate several signals using DMA controller. For each press on User push-button, a signal has been selected and can be monitored on the DAC channel one: - Triangle waveform (Channel 1). - Escalator waveform (Channel 1) using DMA transfer.)
