Serial.begin() for 16Mhz

Using Arduino Programming Questions
1

Hi All,

May I know if I can use 100000 for Serial.begin()?

The reason why I want to use 100000 is because it has 0% error rate... 115200 has -3.5% error rate

Thanks in advance!

You can use anything you like up to 2,000,000 as long as both sender/receiver are the same

For asynchronous communications, small errors or differences in clock rates are dealt with by the decoding, its why asynchronous is used.

Ah..Okay! Got it!

Thanks for the quick response @blh64 @srnet ! :grinning:

The error rate is in the bit timing, not the received data.

We’re talking about tiny fractions of time here.
Most serial decoders can tolerate ‘up to’ 20% bit timing errors.
