One of my customers wants to use 14 GPIOs in Sigma DSP.
I recommend the ADA1463, but the customer wants to use the I/O expander (microchip - mcp23008) with ADAU1450.
This I/O expander is connected to DSP and I2C.
Is there any way to operate I/O expander using I2C communication after DSP self-booting?
(The self-booting circuit is planned to be configured as I2C.)
If possible, please tell me how to implement it in SigmaStudio.
