This article will rewrite the handcrafted OS – a function running the minimum core code of FREERTOS, as shown in the figure below. Mainly: rewriting vTaskSwitchContext + background tick interrupt automatically switches tasks. In fact, the functionality has been completed in two articles, but it seems clumsy to represent using UART. This article aims to … Read more
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
1. Introduction When learning about the 51 microcontroller, we often use the combination of Keil and Proteus for experiments. This simulation saves us a lot of hardware and time costs, allowing us to visually observe the execution process of the code. However, when switching to the STM32 series microcontrollers, Proteus is obviously not supported, but … Read more
Content Overview This article explains the process of creating an 8-channel high-performance logic analyzer. In this manual, we guide you to program the dedicated firmware we provide, allowing you to upgrade your BX71 core board into a high-performance logic analyzer with 500M sampling capability and 8 sampling channels, each with a storage depth of 400M. … Read more
Foreign netizen EL Dr.Guaman has open-sourced a logic analyzer based on the Raspberry Pi microcontroller RP2040, supporting 24 channels and a sampling rate of 100Msps with a 32k sample depth. Friends interested can DIY one themselves. Link: https://github.com/gusmanb/logicanalyzer Cloud Drive: https://pan.baidu.com/s/1MTNOwyy6hNHl1GCi6TGPdQ?pwd=hp6a Extraction Code: hp6a 1.
