Developed by filter solutionsnuhertz, nuhertz is an industry leader in filter design software.The trial version is only available for download on the Internet, and the trial period is only 20 days. After the software is used, the software is basically paralyzed. Of course, you can find the serial number if you are careful.The function is very complete. It is worth mentioning that the curve drawn by the filter solutions can be comparable to that drawn by Protel. I basically use the filter wiz pro

From the perspective of Java development language, short connections are relatively simple to use. Becaus

The microcontroller or microprocessor that conforms to this architecture, it is called the Harvard architecture.

(2) Mosi-master device data input, output from device data
(3) sck-clock signal generated by the master device
(4) CS-enable signals from the master device
Among them, CS is to control whether the chip is selected, that is, only when the chip selection signal is a pre-defined enable signal (high potential or low potential), this chip operation is effective. This allows connecting multiple SPI devices on the same bus.
I have introduced so much about the SPI bus theory.
channel automatically controls the Write Start address and length based on three registers. To send data frames to Ethernet, the DSP only needs to set the TXP of the control register CR to 1.
