Dear expert,
My setup is one UB941 connect with two UB948 in splitter mode.
Now all video display are correct. The only problem is I can only access the 1st UB948 registers at port 0 through I2C from UB941 side but cannot access the 2nd UB948 at port 1.
Two UB948 has different I2C ID (1st is 0x3C, the 2nd is 0x2C). I can see two different ID from UB941 register DES_ID_DES_ID_1 Register (Address = 0x6) with different PORT1_SEL.
Below is the code for UB941 configuration. Basically, I enabled I2C_PASS_THROUGH for GENERAL_CFG Register (Address = 0x3) with different PORT1_SEL in below code.
Could you give some guidance for me? Thanks
i2c_write 0x01 0x80
i2c_write 0x1E 0x01// enable I2C_PASS_THROUGH for port 0
i2c_write 0x03 0x9A
i2c_write 0x1E 0x02 // enable I2C_PASS_THROUGH for port 1
