And I forgot one thing, in my system, I have a EEPROM chip 24LC128, the sda and clk have pull up resistors 1.5K.
I use the EZUSB_WriteI2C(), EZUSB_ReadI2C() functions to write and read data, I think the IIC bus operation functions are working all right.
the 24LC128 device address is 0xA2.
data address is two bytes.
I was very confused about the iic interface of cy22150.
That problem is that the chip device address is not 0x69H, those distributors modify address before sending cy22150 chip. Those fool didn't tell us that!
