== 开发环境准备 == 根据您的系统,选择如下快速指南: * [[Getting Started with Noduino SDK on Linux]] * [[Getting Started with Noduino SDK on Mac OS X]] * [[Getting Started with Noduino SDK on Windows]] <br><br> == 硬件准备 == 此传感器为 I2C 接口,Falcon 接线方式如下: * Sensor_SCL --> Noduino_Falcon_D9 * Sensor_SDA --> Noduino_Falcon_D8 * Sensor_3V3 --> Noduino_Falcon_3V3 * Sensor_GND --> Noduino_Falcon_GND NodeC / SmartNode 接线方式如下: * Sensor_SCL --> SmartNode_IO5 * Sensor_SDA --> SmartNode_IO4 * Sensor_3V3 --> SmartNode_3V3 * Sensor_GND --> SmartNode_GND <br><br> == 编译烧写 == 进入你的 tsl2561 目录: <source lang=bash> $ cd /PATH/TO/noduino-sdk/examples/noduino/tsl2561 </source> 编译、上传一步完成: <source lang=bash> $ make flash </source> 不同平台下,你的串口设备号可能不一样,确认一下你的串口设备,Linux 下 Falcon 开发板可能被识别为 /dev/ttyUSB1(dmesg 查看),则: <source lang=bash> $ make flash ESPPORT=/dev/ttyUSB1 </source> Windows 下 Falcon 开发板可能被识别为 COM6(控制面板 --> 设备管理器里查看),则: <source lang=bash> $ make flash ESPPORT=COM6 </source> <br><br> == 查看结果 == 上传完之后,用串口工具,用 115200 的波特率打开串口,即可看到串口在持续输出传感器测得的值: Windows 下可用串口调试助手这类插看 Linux 下推荐使用 picocom: <source lang=bash> $ sudo apt-get install picocom $ picocom -b 115200 /dev/ttyUSB1 picocom v1.7 port is : /dev/ttyUSB2 flowcontrol : none baudrate is : 115200 parity is : none databits are : 8 escape is : C-a local echo is : no noinit is : no noreset is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv imap is : omap is : emap is : crcrlf,delbs, Terminal ready ...... ...... </source> Ctrl + a q 退出 picocom <br><br> == 代码示例 == <source lang=c> #include "noduino.h" #include "tsl2561.h" irom void setup() { serial_begin(115200); if (!tsl2561_begin(TSL2561_ADDR_LOW)) { serial_print("Could not found TSL2561 sensor!\r\n"); while (1) {} } tsl2561_setGain(TSL2561_GAIN_16X); // set 16x gain (for dim situations) // Changing the integration time gives you a longer time over which to sense light // longer timelines are slower, but are good in very low light situtations! tsl2561_setTiming(TSL2561_INTEGRATIONTIME_13MS); // shortest integration time (bright light) } void loop() { // Simple data read example. Just read the infrared, fullspecrtrum diode // or 'visible' (difference between the two) channels. // This can take 13-402 milliseconds! Uncomment whichever of the following you want to read uint16_t x = tsl2561_getLuminosity(TSL2561_VISIBLE); serial_printf("Luminosity:\t %d\r\n", x); // More advanced data read example. Read 32 bits with top 16 bits IR, bottom 16 bits full spectrum // That way you can do whatever math and comparisons you want! uint32_t lum = tsl2561_getFullLuminosity(); uint16_t ir, full; ir = lum >> 16; full = lum & 0xFFFF; serial_printf("IR:\t\t %d\r\n", ir); serial_printf("Full: ", full); serial_printf("Visible:\t %d\r\n", full - ir); serial_printf("Lux:\t\t %d\r\n\n", tsl2561_calculateLux(full, ir)); delay(3000); } </source> <br><br> == 扩展阅读 == ;;更多问题参考: * [[Noduino]] <br><br> <br><br> <br><br>
