Communication protocols designed for embedded devices typically fall into three categories: Considering the limited memory and computing power of embedded devices, fixed binary is the preferred communication protocol. The following analyzes the characteristics that embedded device communication protocols should have. Simplicity Ensuring that the protocol is a simple solution is crucial; complexity often leads to … Read more
Previously, we introduced how to create a logic analyzer and oscilloscope using RP2040. Today, we will build a logic analyzer using FPGA. Currently, the mainstream architecture of logic analyzers in China is based on FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has kept it in … Read more
