In my last post I say that i want to start from the beginning and i don't mention Atmel in it.
I never say that the master microcontroller will be Atmel8051 (In some olther posts I say „AVR or something faster“so it will be ~ 1 clock per instruction). The problem till now was how to use atmel 8051 series slaves, but not to lose the possibility to go faster then they can do(sounds good 400Mbytes max). I never say that I want to transfer 400Mbytes with Atmel 8051 chip(It is impossible). Thats way I came to conclusion to separate the bus to more than one. One for faster devices, and one for slower ones. And here comes one new question. What if on the open collector bus(my fast bus), more then 2 devices start to transfer(for some reason). And one of them transfer 0 and the other transfer 1 (they are in push-pull state). In this situation am i wrong or the ports will be damaged. If I am thinking right, how to protect from this situation? |
