TLC59116问题求助

Other Parts Discussed in Thread: TLC59116

使用TLC59116的经典电路控制16路LED灯,但是配置寄存器后,引脚输出没有变化

直接点亮全部LED灯:

I2C_WriteData(0xC0, 0x14, 0x55);     //(设备地址,寄存器地址,数值)

I2C_WriteData(0xC0, 0x15, 0x55);    

I2C_WriteData(0xC0, 0x16, 0x55);    

I2C_WriteData(0xC0, 0x17, 0x55);    

能够从寄存器中读取其值已经被配置为0x55,其它寄存器缺省,但是引脚电压没有变化。

使用ALLCALLADR依然没有效果:

I2C_WriteData(0xC0, 0x1b, 0xda);    

I2C_WriteData(0xda, 0x14, 0x55);  

请问假如只点亮全部LED灯是否还需要配置其它寄存器。
