求助：SEN0158红外定位探头使用方法
本帖最后由 Ricky 于 2014-3-26 13:22 编辑最近买了一个SEN0158红外定位探头，程序根据arduino提供的改成模拟I2C通信的STC程序，在通过串口把读到的坐标在计算机上显示，可是一直读到1023（全是FF），在红外发射管前晃来晃去没反应。发送数据都有回应，也可能是I2C程序有问题。跪求此模块datasheet或者控制指令。
另附程序：

建议尝试一下：参考arduino的代码， 初始化的时候一次传送两个字节
Write_2bytes(0x30,0x01); delay(10);

改了过后还是输出一个00和15个FF，而且初始化发送代码后无应答了。。 Leotower 发表于 2014-3-20 09:36

噢，发送2个字节之前忘记发送地址了。。成功了，真心感谢！！！！ 祝贺:)如果方便，您做的应用可以发到论坛上展示一下, 期待中 请问你是用什么单片机进行下载运行的啊？
