I am attempting setting up a basic software serial communication from an attiny85 chip to serial through an arduino uno board.
ATTINY85 chip is set to 8mhz internal oscillator
I have searched the internet and followed many examples.
Softwareserial is working ok when used directly from arduino onboard chip
The ATTINY85 chip works ok with the blink sketch
however when using this sketch:
SoftwareSerial mySerial(3,4); //rx, tx
and have pins 3 and 4 connected to rx/tx on arduino uno board
I get a response in the serial window every second of ÿÿÿÿÿÿÿÿÿÿ
Has anyone seen this and knows why this is happening
