softwareserial library and manchester coding.

Projects General Guidance
1

Hello!

Im being successful using software library to transmit data between 2 wired arduinos as part of a larger project using VLC as communication.

I want to send data manchester encoded and i need the clock that software serial library uses so i can connect, clock and data, to a xor port and then get my manchester coded data.

Anyone knows how (or in which pin) i can get the clock?

Thanks in advance,
Fernando Oliveira

SoftwareSerial doesn't use any other than the system clock. It uses an interrupt (either external or pin change) to start the reception routine and then uses delay loops to receive or send data.

Shame...

Also, what are the input digital voltages min (for 'high') and max (for 'low')?

Thanks

For which board?

Arduino UNO...

I have a signal that goes from0 to almost 4V so i am sure arduino will read High or LOW. Just wanted to know the levels so i could justify them...

Thanks

The limit for a 5V version (as the UNO is) is around 3V for a HIGH and 1V5 for a LOW according to the datasheet.

Ah.... :smiley: Awesome .....working as intended... :wink:
