使用EA画开机MCU记忆上次下点时的亮度信息，上报给MCUCommservice，MCUcommService上报给SettingService，settingService上报给WorkModeManager，WorkModeManager下发背光开关给SettingService，SettingService下发给MCUService，MCUService下发给MCU，MCU接到背光开关来判断是否打开背光

这个问题需要你了解一些嵌入式系统开发的知识。首先你需要在EA中画出MCU的记忆亮度信息以及它们之间的关系和通信流程。然后，你需要编写一个程序来实现这个功能，将亮度信息上传到MCUCommservice，然后经过一系列的传递和处理后，最终实现背光开关的控制。这个过程中需要使用到一些通信协议和数据格式的知识，例如CAN、UART等，以便实现数据的传输和解析。建议你多了解一些相关的嵌入式系统开发的知识，例如硬件编程、通信协议以及数据处理等方面的知识。

用英文帮我给ea写一封申诉邮件

Dear EA Support Team,

I am writing this letter to appeal a recent ban that has been placed on my account. I am not entirely sure of the reason behind this ban, but I am hopeful that it can be lifted and my account can be restored.

I have been an active user of your platform for several years now and take great pride in abiding by the rules and regulations outlined in your terms of service.

使用Assertions给测试类中断言异常，java代码示例

当使用JUnit或TestNG等测试框架时，可以使用断言（assertion）来验证预期的异常是否被抛出。下面是一个示例代码，展示了如何使用断言来断言异常：

import org.junit.Test;

public class ExampleTest {

    @Test
    public void testException() {
        try {
            // 在这里调用可能会抛出异常的方法
            throw new RuntimeException("这是一个异常");
        } catch (RuntimeException e) {
            // 使用断言来验证异常的类型和消息
            assert e instanceof RuntimeException;
            assert e.getMessage().equals("这是一个异常");
        }
    }
}

在上面的示例代码中，我们在`testException`方法中抛出了一个`RuntimeException`异常，并使用断言来验证它的类型和消息。如果断言失败，测试框架会将测试标记为失败。

请注意，在使用断言时，需要确保在测试类中启用了断言功能。可以通过在运行Java虚拟机时使用`-ea`参数来启用断言，或者在IDE中设置断言选项。
