Whether to switch off the CS before the next transfer when the current transfer has been completed. 1 indicates to switch off the CS; 0 indicates to switch on the CS. delayUs uint16_t SpiMsg::delayUs Description: Delay (in microseconds) before starting the next transfer. The value 0 ...
event-spring-boot-starter是一个基于springboot starter机制,结合SPI 接口设计思想实现的事件处理工具组件,旨在提供简单的事件处理编程模型,让基于事件的开发更简单灵活,内部实现基于guava EventBus 实现,扩展方便,集成使用简单。 背景介绍 业务背景 1、我们在日常开发过程中经常遇到一些特殊业务场景(非分布式环境下,分布式...
