Uart Interrupt Wipy 2.0

[jakarman12]

I need to use the uart interrupt but I found the example for wipy 1.0 but for wipy 2.0 I can't make it work.

Is there any example to use uart irq for WiPy 2.0?

Hi @jakarman12

Could you please give an example (in MicroPython) of what you are trying to do?

Thanks!

Hi @bucknall:

Of course, here it is.

from machine import UART
import pycom
import time

uart = UART(1, baudrate=9600)
pycom.heartbeat(False)
UART.irq(UART.RX_ANY, priority=1, handler=irq_uart1, wake=machine.IDLE)

def  irq_uart1 ():
    print ("Uart Interrupt")
    pass

uart.write('hello')

while  1:
    pass


This is the error: 
**Traceback (most recent call last):

@jakarman12 Ah ok!

We currently do not support interrupts in the ESP32 MicroPython branch for the UART bus. I know this is on the roadmap of things to do, so I'll check with Daniel to see where we are with this!

Thanks for your patience!

Thanks @bucknall

Do you have an approximate date for a new update?

Hi Guys,
there are updates that concern UART interrupt?
This aspect is very important!
Thanks
