TI中文支持网Part Number:LP8866-Q1
你好，
当我通过IIC改变LP8866 LEDdriver输出电流后，输出电压也随之改变，但我读取1C寄存器的值一直都是0x06F5,不管我怎么改变电流一直都是这个返回值，请帮忙看看这是怎么一回事吗？
需要其他设置其他的才能读取到不同的值吗？我想检测到输出电压的值，谢谢~

输出电压27V，你们读取1C寄存器能读取到不同值吗？我读取的话一直都是0x06F5，对应的电压值为12V。你们如果有读取到的话，我可以参考你们的代码吗？

您可以使用GUI对其进行测试，它可以根据您想要的目标电压进行更改。 当电流发生变化时，增压输出电压会发生变化。 问题可能出在您的软件上。
