FreeRTOS Part Three: Configuration

FreeRTOS Configuration Let us continue Bob’s open-source FreeRTOS series. All RTOS require configuration. In this article, Bob will discuss the configuration parameters available when setting up FreeRTOS. Every real-time operating system (RTOS) I have integrated into embedded systems required configuration. The first was RSX-11, developed by David Cutler for Digital Equipment’s PDP-11 (Figure 1). (David … Read more

Data Communication Between Ethernet and WiFi in OpenWRT System

The OpenWRT system achieves data transmission between Ethernet (wired) and WiFi (wireless) through a multi-layer network architecture design and inter-process communication (IPC) mechanisms. Its core design includes network interface bridging, inter-process communication framework (ubus), firewall and routing rules, and unified configuration management system. The following are the specific implementation principles and key components: 1. Network … Read more
