Problem getting RTC rv8803 working on Pico Micropython

Other
1

I am trying to get RTC rv8803 working on R pico under Micropython with QWIIC. The examples do not work. I use the following code:

#RTC RV8803 test

from machine import I2C, Pin
import sys
import time
import qwiic_i2c
import qwiic_rv8803

i2c = qwiic_i2c.get_i2c_driver(sda=4, scl=5, freq=10000)

devices = i2c.scan()
print(“13: I2C devices found:”, devices)

myRTC = qwiic_rv8803.QwiicRV8803(i2c,50)

def runExample():
print(“\nQwiic RV8803 Example 1 - Set Time\n”)

sec    = 2
minute = 47
hour   = 14
date   = 7
month  = 9
weekday = myRTC.kSunday
year   = 2025

myRTC.set_time(sec, minute, hour, weekday, date, month, year)

while True:
	myRTC.update_time()
	print ("Current Time: ", end="")
	print (myRTC.string_date_usa(), end="")
	print (" ", myRTC.string_time())
	time.sleep(1)

if name == ‘main’:
try:
runExample()
except (KeyboardInterrupt, SystemExit) as exErr:
print(“\nEnding Example”)
sys.exit(0)

This gives the following output and error:

%Run -c $EDITOR_CONTENT

MPY: soft reboot
13: I2C devices found: [50]

Qwiic RV8803 Example 1 - Set Time

Traceback (most recent call last):

I think you need a MicroPython driver for the RV8803.

I import the driver: import qwiic_rv8803
