瑞萨单片机显示程序。利用串口实现数据通讯收发液晶屏显示(Risa MCU display program. Using Serial Port to Realize Data Communication Transceiver LCD Display)

说明：  一些有用的例程，大家可以看一看， MSP430F5529官方例程 包含： ADC COMP DMA FLASHWRITE LPM NMI SPI I2C(Some useful routines, you can see that msp430f5529 official routines include: ADC comp DMA flash write LPM NMI SPI I2C)

ADC0通道采集电压以波形形式显示到2.8寸TFT触摸液晶屏上，ADC输入管脚为60管脚(ADC0 channel acquisition voltage to waveform display to the 2.8-inch TFT touch LCD screen, ADC input pin for the 60-pin)

Atmega8+AD7730 source code. Do not forget to set chip select and DataRdy pin settings. This is not copied from internet. It works. COOL:)

可虛擬兩個RS-232或者是多個RS-232互傳資訊，此源码維Visual Basic所編寫。(Can be a virtual two RS-232 or RS-232 over pass each other information, this source code written by Visual Basic dimension)

RVM源代码，有例子说明，供初学者使用，不错的代码(this is a code of RVM, which can help the people who begin to study RVM)

赛普拉斯单片机的C语言开发说明，比较适合于刚刚入门的工程师(Cypress MCU C language development that are more suitable for the engineer just started)

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=)

利用28335自带的ADC采集两路模拟正弦信号，用DMA方式将采样值写入内存，用epwm控制采样周期。利用FFT求得两路正弦信号的相位差。(Sampling two analog sinusoidal signals, write them to the memory by DMA controller. The sampling period is controlled by the EPWM module. Calculate the phase difference by FFT method.)

包含位置式PID算法、积分分离式PID，包括广义互相关函数GCC时延估计，真的是一个好程序。( It contains positional PID algorithm, integral separate PID, Including the generalized cross-correlation function GCC time delay estimation, Really is a good program.)
