0x00 PrefaceIn the first article: the Never-fading Wave (i): Radio introduction We learned about the history of radio and some of the physics of Radio, in the second we will use HACKRF to record the wireless signal of the doorbell, and then replay the doorbell signal.The doorbell was bought from a treasure,0X01 Environment Construction:Mac can be used GQRX and HA

Doorbell's interrupt-to-core mechanism is implemented by the DOORBELLX_ICRRX register, with a total of eight ICRR registers. When doorbell packets is received by the SRIO peripheral, Theseicrrs Routedoorbell interrupt requests (indicated in the ISCR register) from T He associated doorbell Icsrto user-selected interruptdestinations. Each of the four doorbells can is mapped to these registers. Each pair of

-side response. 3, Swrite: Stream write, the data length must be an integer multiple of 8 bytes and does not require a receive-side response. 4, Nread: normal read operation. The number can be accessed directly from the peer. A packet with a maximum of 256bytes, that is, the master DSP to read the slave DSP memory data. The above refers to Srio's direct IO package, in fact c66x DSP Srio package has direct IO packet, doorbell package, message package a

requires the receiving end to respond. 3. swrite: stream write. The data length must be an integer multiple of 8 bytes and the receiver is not required to respond. 4. nread: Common read operation. You can directly retrieve the number of memories from the peer. The maximum size of a package is 256 bytes, that is, the master DSP reads the data in the memory of the slave DSP. As mentioned above, SRIo's direct Io package, in fact, c66x DSP's SRIo package includes direct Io package,

The single-chip Interrupt System Concept: What is interrupt, we introduce it from a routine in life. When you were reading a book at home, the phone suddenly rang. You put down the book, answered the phone, talked to the caller, put down the phone, and came back to continue reading your book. This is the phenomenon of "interruption" in life, that is, the normal working process is interrupted by external events. The interruption in our daily life is also very beneficial for us to learn the interr

Slope_rad is the number of slope radians for a point, and Azimuth_rad is the number of radians in the direction of the Sun's Rays. Aspect_rad is the number of slope radians for a point.The angle of the lighting source that calculates the hillshade is the sun height angle by default, But when it is actually calculated. The Sun Zen
