Something about timings

There is not that much information about the fbus protocol in the internet. So I decided to gather the informations I am stumbling over in this Blog. Maybe there are more or less useful information for you.

In a avrfreaks discussion turboscrew talked about some timings of the fbus during initialization.

If you first output the 0x55's and then the query frame taking care that the time between the 0x55's or the bytes of the query message do not exceed 5 ms and that there is, say, 10 ms delay between the last byte of the 0x55 chunk and the first byte of the query, and still no response, then I'd suspect that there is still something wrong with the cable.

I am not sure if this is correct, but it is information ;-)
