check onewire protocol speed how many bits/second (i think it´s about 16kbits/s) how many bits to change port bits (i think about 200bits? must check...) with these numbers you have onewire speed somethink like: 200bits * 16kbit/s = 0,0125 seconds
you can do it, i don´t know, but i think it´s very slow, must try 2011/1/27 patyrk <[email protected]>: > Dnia 2011-01-27, czw o godzinie 14:29 -0200, Roberto Spadim pisze: >> check my last email >> we can do it! but it´s slow > > You wrote >>> i used lcd on pic18f, putting charset is a very slow feature (for >>> onewire lan) ok it can run on 1bit/s network but will wait a very big >>> time > So if the speed is 1bit/s why does displaying normal text using > printf "123456789abcdef" > LCD_H/screen > takes about one second?
