开发
- 请先确定+3.3v电源的电流能达到200ma，不推荐直接采用FT232R调试，因为FT232R输出的+3.3v的电流太小。 The FT232R datasheet says you can draw up to 50 mA from its 3.3V output.
Arduino库及支持包
库的使用事项
- CC3000Patch库是用来升级firmware之用，不可以与Adafruit_CC3000库同时启用；
- 如果要想使得这两个库兼容Microduino Core+：
- 你需要先打开库目录中的“Adafruit_CC3000_4Patching.cpp”（CC3000Patch）或者“Adafruit_CC3000.cpp”（Adafruit_CC3000）文件；
- 在文件中找到“#elif defined(__AVR_ATmega1281__) || defined(__AVR_ATmega2561__) || defined(__AVR_ATmega2560__) || defined(__AVR_ATmega1280__)”这一行；
- 将这一行之后加上“ || defined(__AVR_ATmega1284P__) || defined(__AVR_ATmega644P__) ”这一句即可。
- CC3000Patch：
- CC3000Patch可用来升级CC3000的firmware，你需要将CC3000Patch.ino放到新建的\examples\CC3000Patch\目录中；
- 你需要确定程序中的IRQ、VBAT、CS引脚都设置正确，即“#define CC3000_IRQ 2 ”、“#define ADAFRUIT_CC3000_VBAT 9”、“#define ADAFRUIT_CC3000_CS 10”；
- 更详细的使用方法参考作者的README
- Adafruit_CC3000：
- 你需要确定程序中的IRQ、VBAT、CS引脚都设置正确，即“#define CC3000_IRQ 2 ”、“#define ADAFRUIT_CC3000_VBAT 9”、“#define ADAFRUIT_CC3000_CS 10”
应用
升级CC3000的firmware
- 推荐用CC3000Patch库将CC3000的firmware升级至1.24，详细的使用方法参考作者的README
- （注意事项：升级firmware的过程是通过串口监视器进行操作的，请将Arduino IDE的串口监视器的换行结束符设为“换行和回车”）
- 升级完成后，将CC3000Patch库删除，启用Adafruit_CC3000库，就可以开始里面的examples了！
SimpleLink™ Wi-Fi SmartConfig™ 功能
- 如果要用到SimpleLink™ Wi-Fi SmartConfig™ 功能:
- 以IOS为例，先在App Store里下载TI WIFI SMARTCINFIG；
- 将IOS设备连接上路由器，打开TI WIFI SMARTCINFIG，在Password中填上路由器密匙；
- 将Adafruit_CC3000库examples中的SmartConfigCreate下载到Microduino；
- 打开串口监视器（波特率115200），当出现“Waiting for a SmartConfig connection (~60s) ...”时候，按下TI WIFI SMARTCINFIG的Start，等待串口结果。
