[DSP program] ADC_DAC

Description: This example streams input from a ADC source to a DAC. An analog signal is acquired block-by-block into SDRAM from the ADC (an AD9244 in this example). The frames are then output with a one-frame delay to the DAC (an AD9744 in this example). In this example, no processing is done on the frames. They are passed unaltered.

[VHDL-FPGA-Verilog] UART

Description: 用FPGA实现了RS232异步串行通信，所用语言是VHDL，另外本人还有Verilog的欢迎交流学习，根据RS232 异步串行通信来的帧格式，在FPGA发送模块中采用的每一帧格式为：1位开始位+8位数据位+1位奇校验位+1位停止位，波特率为2400。由设置的波特率可以算出分频系数，具体算法为分频系数X=CLK/(BOUND*2)。-Using FPGA to achieve the RS232 asynchronous serial communication, the language used is VHDL, In addition, I also welcome the exchange of learning Verilog, according to RS232 asynchronous serial communication to the frame format, in the FPGA module used to send each frame format : the beginning of a bit+ 8-bit data bit+ 1 bit odd parity bit+ 1 bit stop bit, baud rate for 2400. By setting the baud rate can be calculated at the frequency coefficient, the specific algorithm for the sub-frequency coefficient X = CLK/(BOUND* 2).

[Embeded-SCM Develop] SPI_TEST

Description: The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a "four wire" serial bus, contrasting with three, two, and one wire serial buses.-The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard named by Motorola that operates in full duplex mode.
