When We try to add second encoder, the led is always yellow. My understanding is that the first encoder was terminated by default, thus second encoder is not enabled.
document mentioned to write REG 4D, 4C AND 4B to change the setting to disable the termination of first encoder.
The problem is that we do not find any way to change REG setting, or do we have to?
We just simply set our motor encoder to be i2c_1 and i2c_2 in configuration. That seems not help. LED of second encoder is always steady yellow.
