From looking at the SDI-12 protocol it states the following with regards to the data:
1 start bit
7 data bits, least significant bit transmitted first
1 parity bit, even parity
1 stop bit
From looking at some other posts I see you should be able to change the bits and parity by using the following:
UCSR0C = (2<<UPM00)|(0<<USBS0)|(2<<UCSZ00)|(0<<UCPOL0); // configure for 7E1 not 8N1
My question has to do with the LSB transmitted first part. Is this standard in a typical Serial.print command or would I have to format the serial data differently before sending out the serial lines? and the corresponding receive?
Any help would be greatly appreciated. And yes, I’m aware that SDI-12 is completely different from RS232 as far as how the tx/rcv lines are set up. I just need to make sure the data is going out and being received correctly.
