Hello.

I want to ask that is there someone who is good in vhdl or which know 
some good sites about vhdl sources. I want to implement to fpga some 
buses. I have 5 specified sensor which comunicate trought OneWire, I2C 
and SPI. I try a lot of codes but were very complex for me to 
understand. So if there is someone who can help me please write me back. 
thanks a lot

Lukas

Huh, funny strategy.

First you must understand how the bus is working: SPI for example are 
simple coupled shift registers. The I2C is also clk synced, but a little 
more tricky at transacting the bus (START, STOP, CLOCK STRETCHING). And 
at the one-wire you must have a more sophisticated FSM to control the 
interactions and the protocol.

And what will happen with the data you aquired?
What sensors do you have?
