Cotton Belt 819 is a L-1 class 4-8-4 "Northern" type steam locomotive and is also the official state locomotive of Arkansas. [2] . It was completed in February 1943 and was the last engine built by the St. Louis Southwestern Railway, which was affectionately known as "The Cotton Belt Route" or simply "Cotton Belt".

SSW 819 Steam Locomotive at the museum. Here's the numerals on 819's sand dome on the shop floor. 819 has been napping for about 12 years now. I think it's way past time for it to stretch her legs on the high iron.

At that point, the SSW decided to go with a four-wheel leading truck and the result was the L1. The firebox heating surface includes 107 sq ft (9.9 sq m) of thermic syphons (two in the firebox, one in the combustion chamber) and 104 sq ft (9.65 sq m) in the combustion chamber.

2020年2月20日 · LTSSM全称是Link Training and Status State Machine，有以下11个状态： Detect, Polling, Configuration, Recovery, L0, L0s, L1, L2, Hot Reset, Loopback, Disable. 这些状态分为5大类： 1、链路训练状态（Link Training State）：Detect->Polling-> Configuration ->L0. 2、重训练状态（Re-Training（Recovery） State）：Recovery. 3、软件驱动功耗管理状态（Software Driven Power Management State）：L0->L1/L2/L0s.

2025年1月9日 · 案例： 假设我们需要在PCB板上连接一个微型滑动开关，实现开关控制灯的亮灭。 操作步骤如下： 选择合适的微型滑动开关，并准备好焊锡、导线等工具材料。 在PCB板上设计开关位置，打孔并安装开关。 通过焊接将开关固定在PCB板上。 使用导线连接开关的两端到灯的正负极。 确保连接正确。 测试开关，通过滑动开关控制灯的亮灭效果。 代码示例（如果需要）： pinMode(switchPin, INPUT); pinMode(ledPin, OUTPUT); digitalWrite(ledPin, HIGH); // 灯亮. } …

此篇介绍 L1 Substate 低功耗状态。 下一篇介绍L2低功耗状态。 L1 PM Substate分为： L1.0 对应于传统的L1链路状态，前一篇已经介绍过； L1.1 比L1.0省电， 保持tx common mode电压，关闭Electrical idle exit detect电路，关闭参考时钟和PLL； L1.2 比L1.1省电， 关闭tx common mode电压，关闭Electrical idle exit detect电路，关闭参考时钟和PLL， 可以选择关闭Main Power； 以下介绍一下最关键的CLKREQ# CLKREQ#是一个open-drain管脚，用于 关闭参考时钟.
