Model Context Protocol (MCP) 简介
AI天才研究院
05-11 366
Model Context Protocol (MCP) 是一个开放协议，旨在标准化应用程序如何为大型语言模型（LLMs）提供上下文。MCP 类似于 AI 应用的 USB-C 接口，提供了一种标准化的方式，将 AI 模型连接到不同的数据源和工具。MCP 的核心架构采用客户端-服务器模式，主机应用程序可以连接到多个服务器，访问本地和远程数据源。MCP 提供了预构建的集成、灵活的 LLM 供应商切换以及数据安全的最佳实践。开发者可以根据需求选择快速入门指南，构建自己的服务器或客户端，或使用预构建的服务器。MCP

The eCAP module represents one complete capture channel that can be instantiated multiple times, depending on the target device. In the context of this guide, one eCAP channel has the following independent key resources: • Capture inputs can be connected using the Input X-BAR • 256:1 input multiplexer • Output X-BAR is used to configure output in APWM mode • 32-bit time base (counter) • 4 x 32-bit time-stamp capture registers (CAP1-CAP4) • Four-stage sequencer (modulo4 counter) that is synchronized to external events, eCAP pin rising/falling edges. • Modulo counter status register (MODCNTRSTS) to indicate sequencer state • Independent edge polarity (rising/falling edge) selection for all four events • Input capture signal prescaling (from 2-62 or bypass) • One-shot compare register (two bits) to freeze captures after 1-4 time-stamp events • Control for continuous time-stamp captures using a four-deep circular buffer (CAP1-CAP4) scheme • Interrupt capabilities on any of the four capture events • Separate DMA trigger • EALLOW protection to control registers • Signal monitoring capability for edge, pulse width, and period • DMA event generation capability in APWM mode • ADC SOC event generation capability, to trigger ADC conversion 21.3 Configuring Device Pins for the eCAP The Input X-BAR connects the device pins to the module as input. Any GPIO on the device can be configured as an input. The GPIO input qualification can be set to synchronous or asynchronous mode by setting the GPxQSELn register bits. Using synchronized inputs can help with noise immunity but affects the eCAP accuracy by ±2 cycles. The internal pull-ups can be configured in the GPyPUD register. Since the GPIO mode is used, the GPyINV register can invert the signals. New to the Type 1 eCAP module, a 128:1 input multiplexer must also be configured (see Figure 21-3). This multiplexer can select a variety of inputs detailed in Table 21-1 by configuring ECCTL0.INPUTSEL.

嗯，用户这次问的是TMS320F28P65x芯片的eCAP模块配置细节，特别是输入路径上的X-BAR和多路复用器结构，还点名要了解GPIO限定模式。看来用户正在做底层驱动开发，需要精确掌握信号流路径。翻看历史记录，我之前已经...
