Using UART in Nicla Vision

Official Hardware Nicla Family Nicla Vision
1

Hi everyone,

I am using Nicla Vision for Arduino. i am trying to setup UART communication, but it not working.

I am not getting the signal from the UART Pin. below are the code that i am using for communication and to capture the data i am using oscilloscope.

import time
from pyb import UART

# Init UART object.
uart = UART(4, 19200)

while True:
    uart.write("Hello World!\r")
    time.sleep_ms(1000)

[here is the link for complete data sheet of this board]

I also tried the below code to modify the RX and TX pin, but that gives me "TypeError: extra keyboard argument given" to this line uart = UART(1, baudrate=9600, tx=Pin("PA9"), rx=Pin("PA10"))

here is the complete code

from machine import UART, Pin
import time

# Create a UART object on UART port 1 with a baud rate of 9600, using specified pins
uart = UART(1, baudrate=9600, tx=Pin("PA9"), rx=Pin("PA10"))

while True:
    uart.write("Hello, receiver!")
    time.sleep(2)

Hi @pankaj15 ,

You can use the script mentioned below.

# UART Control

import time
from pyb import UART

# Init UART object.
uart = UART("LP1", 19200)

while True:
    uart.write("Hello World!\r")
    time.sleep_ms(1000)

Best,
