01 UART Outputting Analog Signals 1. Introduction Yesterday, someone commented on the “Serial Music” VLOG, raising a very good question. That is, what are the advantages of using the microcontroller’s UART output signal low-pass filtered to obtain an analog signal compared to using traditional PWM output signal low-pass filtered to obtain an analog signal? In … Read more
Basic Theoretical Knowledge i. Parallel Communication/Serial Communication ii. Asynchronous Communication/Synchronous Communication iii. Half-Duplex Communication/Full-Duplex Communication i. Parallel Communication/Serial Communication Parallel communication: Fast transmission speed, transmitting 8 bits at once, but high communication costs, requiring 8 independent channels. It does not support long-distance transmission. Used in devices such as printers and scanners, for example, the DB-25 … Read more
Hello everyone! Today I want to share with you a powerful C library – FFTW (Fastest Fourier Transform in the West). It is one of the fastest open-source libraries for Fourier Transform and is widely used in fields such as signal processing and image processing. Don’t worry if you don’t know what Fourier Transform is; … Read more
Requirements Design a bandpass filter and verify its functionality. 1. Use MATLAB to Design Filter Coefficients Find the Filter Design Tool on the MATLAB homepage after locating the APP, and use this tool to generate the coefficients for the digital filter, which will later be used to configure the FIR IP core on the FPGA. … Read more

Follow+Star Public Number, don’t miss the wonderful content Source | Electronic Circuit Development Learning Students learning microcontrollers generally encounter FPGAs. Some readers might ask: What can FPGAs do? Are they better than microcontrollers? To put it simply, FPGAs can perform tasks similar to microcontrollers in certain areas, and in some fields, FPGAs are far superior … Read more
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
