I2C Address in FPGA without external hardware pins ?

[tramu]

Dear sir,

Can I implement a I2C slave address in a FPGA as fixed ?
Or do i need to use 3 hardware FPGA pins for address lines to implement a slave address ?

I have seen I2C devices whose address is fixed and can't be changed.
So, if I implement I2C slave address as fixed in FPGA (without A0, A1, A2 hardware pins), then i will be saving FPGA pins.

Please help.

Regards,
Thulasi

Off course you can. It's just a 3 bit logic vector somwhere in the I2C code. It really doesn't matter if its value comes from pins or an assignment in your code
