1, Experimental principle 1.1 stm32f103c8t6 introduction STM32F103C8T6 is a 32-bit microcontroller based on Cortex-M3 core launched by St. the hardware is packaged with LQFP48 and belongs to STM32 series of microcontrollers of ST company. 1.2 stm32f103c8t6 lighting principle of running water lamp Registers can store data and instructions, and ...

1, Register introduction Register, according to Baidu Encyclopedia, register is an integral part of the CPU. Registers are high-speed storage components with limited storage capacity. They can be used to temporarily store instructions, data and addresses. Generally speaking, registers store things. What we store is just from our objective thin ...

1, Initialization settings of GPIO port: clock configuration, I / O mode setting and maximum rate setting      1. Because the pins to be operated by the water flow lamp are all on the GPIO port, it belongs to the AHB bus according to the system structure diagram, so the reset and time control of the port to be used are ...
