Hi everybody,

I am new to the PIC world. I planning to design a RS485 network with PIC's,
there will be 32 nodes at max, 1 of them is a master. My questions are

1. Which PIC model is suitable for RS485 network ?
2. What kind of extra components do I need?

A circuit diagram would be good. Thanks a lot.

Ali GOKSU

Hi there, i have used 32 PIC16F84 in 485...And works fine...
You have to study the 75176 or MAX485...

I use the CCS C compiler...

I can help You!

Any PIC can drive RS485; one with built in UART will be easier.
Use a MAX485 or similar part to drive the RS485 - no other parts are needed
unless you want terminating resistors.

The MAX485 is like a MAX232, except it only transmits OR receives; a third
output pin from the PIC controls the data direction.

Look at the new PIC16C87x family.  Its 9-bit addressable UART seems
ideal for an RS485 multidrop network.
