For a faster version, see the C language implementation of FFT and IFFT source code, which does not rely on a specific platform. The porting is very simple, does not rely on other libraries, and allows custom point counts. The algorithm is based on the usage instructions of the FFT algorithm and the C language … Read more
Step 1: Create the physical chip. A microcontroller, generally understood as MCU (Microcontroller Unit), includes components such as timers, ALU (Arithmetic Logic Unit), memory, registers, buses, etc. A typical microcontroller also includes GPIO, serial ports (UART), DMA, coprocessors, AD/DA, etc. Understand the diagram below Prerequisites: Computer Organization Principles, Microcomputer Principles. Pipeline Prerequisites: Digital Logic Circuits, … Read more

A microcontroller is actually an early term, initially referred to as a single-board computer or microcontroller. At that time, the processing power of microcontrollers was not very strong. Now, we mostly use microcontroller units (MCUs), which integrate a central processing unit (CPU), memory (ROM, RAM), input/output ports (I/O), timers, counters, serial communication interfaces, and other … Read more
