uart problem
Does the micropython support the receive interruption of uart? And the API function is what? thank you
Re: uart problem
When the read_buf_len (argument to the init function) is non-zero, then interrupts enabled to put received characters into the buffer.
The default is a read_buf_len of 64.
The default is a read_buf_len of 64.

Re: uart problem
There isn't a user callback. The UART performs I/O using interrupts in the background. You need to poll the any() method to determine how many characters are in its buffer.
