In embedded development, reliable communication between devices has always been a challenge. Today, we will share an excellent open-source project—LwPKT, and see how it solves complex communication protocol issues with less than 1000 lines of code. 1. Pain Points of Embedded Communication In embedded development, we often encounter the following issues: Memory Constraints: MCUs have … Read more
UART in Embedded Communication Protocols In the first phase, we have mastered the basic theory and preliminary practice of UART, including the basic concepts of frame structure and baud rate. Now, we will delve into the configuration details of the UART protocol, particularly focusing on the calculation of baud rate error and the application of … Read more
SACP (Snapmaker Advanced Communication Protocol) is the data communication protocol for Snapmaker devices, used for data transmission between the controller, PC (Host), and HMI (Human-Machine Interface). From the design philosophy of this protocol, it can meet the following basic goals: Reliability: Packet header CRC8 check + Checksum data integrity verification Flexibility: Supports request/response mechanism (SACP_ATTR_REQ … Read more
