Got a little question about the RS485 Lib. I used this one from Nick Gammon ( http://www.gammon.com.au/forum/?id=11428 )
I used this lib to make my own houseautomation with an arduinoNanoV3 for Master.
The Slaves are build with Atmega und Attiny84. The Communication made with NewSoftSerial under 0023
The Master Communication worked fine with NewSoftSerial an compiled under 0023.
So yesterday i started to work with 1.0.1, i read on the main site of arduiniana who developed the newsoftserial under 00xx that the SOftwareSerial wich included on 1.0.1 is the same way. I only have to chance the NewSoftSerial to SoftwareSerial.
It worked on the slaves with the 1.0.1. On the master (with the abolutly same code only the changes of NewSoftSerial =>SoftwareSerial) it wont worked i tried many times with also with checking the buffer over hardware serial with an Terminalprogramm. But it wont work.
Do you know about Problems with you rs485 Softserial and arduino 1.0.1.
With the Aruino IDE 0023 worked it completly
WIth the Arduino 1.0.1 it wont work. Bothe IDEs compiled this code without Failure.
The Master Code (wich i have the problems)
These Verison worked with 0023
I only change for Working with 1.0.1 The WConstans.h => adruino.h
and the NewSoftSerial => to Software Serial (also the beginning of th class)

I solved the problem after testing testing testing testing testing testing testing. Only change the RS485.print => RS485.write
Glad we could help
