0. PrefaceWhy do you want to use cross-compilation for "1" The speed at which the cross-compilation tool is developed faster. The Raspberry Pi has already installed the GCC toolchain, which can be compiled directly from the Raspberry Pi source code to generate the executable file. At the same time, the PC can also use

DS is a serial input pin, so-called serial is to make the data on a signal line in order to transmit one by one, like a string of candied fruit. This pin we received from the Raspberry Pi at any one of the Gpio ports (output mode). The SHCP is the clock pin for the shift regist
