I am working on FPGA project where I have to configure the onboard ICs with SPI interface specified in their datasheets and few with the I2C interface. I was wondering that, is it possible to bring these SPI interfaces ICs as well on I2C interface? I'll permanently enable the Latch Enable pin to Logic '1'(VCC) and use the SCLK and SDATA pins interface for I2C interface pins because those 2 pins only what I need! Later My HDL protocol logic will take care of it inside the FPGA.
I'm exploring this first time so, Have anyone tried it earlier with these industry standard protocols? Is it even feasible? Especially when the product datasheet tells me that it has SPI and not I2C?
