Hi,
I would like to create 1-wire network using cc1110 (from Texas Instruments) as master and PIC16LF1823 as slaves. For now, I was successfully able to communicate over CAT5 cable of length 4.8m only using pull-up resistor on the line and one slave. However, I would like to make the line a little bit longer so I am designing slew rate control. I found **broken link removed** and I think that the design on the master side should be something like that. However, as I am driving the network with 3.6V, shall the MOSFET, capacitor 220pF and 3.3k resistor be changed? How can I exactly calculate the R and C for the slew rate of 0.8V/usec? As the CC1110 can sink only 4mA, the pull-up resistor should be 100Ohm or can it be lowered?
I would like to get 50m distance and 150 slaves.
Thanks and kind regards,
Gabrijel
