Novice for help! I use a piece of STM32 and max485 chip and two pieces of 6n137 to form an optically isolated 485 communication system, how to test the bit error rate of the system?
And I have read the parameter of the 6N137 photocoupler. If you need to refer to this, you may see the link: []
And I also have some doubts that how to receive and send the test code sequence?
Next, how to judge the occurrence of error codes and whether to compare them one by one?

Looking forward to hearing from you kind help.

Yours sincerely,

To make each day count.
