7x71 RGB柔性屏测评（一）开箱及示例测试
7x71 RGB柔性屏测评（二）儿童节快乐！！
很开心得到了柔性屏的测评机会。正如在申请里所说，RGB LED灯是我最喜欢的元器件，好上手，变化多，充满魔幻。

一、开箱
很快收到了测试品，一个非常轻巧的长方形盒子

拆开后的样子，正面

拆开的样子，背面


做工真是非常的漂亮，通电后运行已写入的程序，DFROBOT向左滚动


二、测试准备：
库文件下载：https://github.com/DFRobot/DFRobot_SerialScreen771

解压缩后，将文件夹复制到Arduino文件夹下的Library中：


三、运行示例文件
运行Arduino IDE-->File-->Examples-->DFRobot_SerialScreen771-master，选择一个文件进行测试


1. 设置显示信息

滚动显示信息“DFROBOT”（不知道为什么显示不出来动图，和前面那个DFROBOT向左滚动的动图是同一个动图）
[mw_shl_code=cpp,false]#include <Arduino.h>
#include <HardwareSerial.h>
#include <SoftwareSerial.h>
#include "DFRobot_SerialScreen771.h"

#ifdef ARDUINO_AVR_UNO
SoftwareSerial Serial1(2, 3); //RX, TX
#endif

DFRobot_SerialScreen771 screen;

void setup() {
    /*Initialize communication interface (Serial1) and debug interface (Serial)*/
    Serial.begin(115200);
    Serial1.begin(19200);
    screen.begin(Serial1);
    screen.setDbgSerial(Serial);
    /*Display string "DFRobot"*/
    screen.setMessage("DFRobot");
}

void loop() {

}[/mw_shl_code]
2. 设置信息列表（displayMessageList.ino）：每3秒显示列表中的一组信息，共8种不同信息

五、初试体会

RGB柔性屏做工精良，色彩饱满，产品维库清晰，简单易上手。

接下来将尝试在其他控制器上使用柔性屏，并搭配其他元器件使用。

不错的灯带，喜欢之
