Previously, we introduced how to make 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 uses FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has allowed it to occupy the … Read more
GUI: Graphical User Interface. In the past, due to the limited resources and processing capabilities of MCUs, there were very few general GUIs based on MCUs. Now, with increased resources and stronger processing capabilities of MCUs, along with growing market demand, GUI functionalities have become richer. Let’s take a look at some common MCU-based GUIs. … Read more
