概述

Fault finding of Printed Circuit Boards (PCBs) can be a difficult process. An easy method to identify short circuits is by using a thermal imaging camera connected to an optical microscope. The live video image can be taken from the camera to a colour display. The product design can be improved by incorporating a low cost MCU, an Embedded Video Engine (EVE) IC, small display and a microscope thermal camera.

添加支持 EVE 的彩色显示器可带来许多好处，包括：

• 提供屏幕菜单，使设备设置更容易
• Overlay images with symbols and text
• Provide on-screen menus to make setting up the unit easier
• Use the touch screen to make the user interface more intuitive without additional buttons or dials

​主要特征​

The following key features of EVE make it ideal for a thermal imaging equipment application:​

• 支持多种屏幕尺寸，例如 3.5 英寸至 10.1 英寸
• 提供电阻式和电容式触摸选项
• 额外的 RGB 到 LVDS 转换 IC 可用于 LVDS 显示器
• Extensive image support for stylish gauges, backgrounds, and symbols
• EVE 连接的闪存芯片支持 (BT81x) 允许独立于主机 MCU 进行图像存储
• 自定义字体允许多语言支持和符号/单位
• 音频输出和内置警告音和指示音等范围
• PWM调光输出可动态调节屏幕背光亮度
