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）
#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() {
}
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
/*!
* file displayMessageList.ino
*
* Initialize 8 information lists M1->M8 and directly print the list of "DFRobot" in the information list.
* @Display a list of previously stored values of "DFRobot"

screen.setDbgSerial(Serial);
delay(5);
/*显示字符串 "DFRobot"*/
screen.setMessage("DFRobot");
/*设置字符移动方向*/
screen.setMoveMode(eMove_left);
/*设置字符移动速度*/
screen.setMoveSpeed(eSpeedLevel_8);
/*设置显示亮度级别*/
screen.setBrightness(eBrightLevel_1);
/*设置屏幕颜色*/
screen.setFullScreenColor(eColor_black);
/*设置屏幕背景色和字体颜色：黑色背景红色字体*/
screen.setDispalyColor(eColor_red, eColor_black);
}
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
