[Uploading Huawei-EPW750-12A-datasheet.pdf…]() 请教一下，华为EPW750-12A读不到数据，日志有读到IIC设备地址： [13:26:20][I][i2c.arduino:102]: Found i2c device at address 0x57 [13:26:20][I][i2c.arduino:102]: Found i2c device at address 0x5F 这个地址是不是在main.hpp中更改？ CSPS PowerSupply(0x5E, 0x56, true); 已经更改为下面的 CSPS PowerSupply(0x57, 0x5F, true); 还是读不到数据，class类已经去掉不知道的寄存器读写 EPW750-12A寄存器 大神麻烦看看这个需要啷个改才支持？

已经解决问题，CSPS PowerSupply(0x5F, 0x57, true);，还有关键是要修改时钟Wire.setClock(100000);
