uart problem

[wwsheldons]

Does the micropython support the receive interruption of uart? And the API function is what? thank you

[dhylands]

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.

thank you

[wwsheldons]

And the callback function is...?

[pythoncoder]

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.

You can also use select on the uarts.
