Hello there,

I am approaching you regarding the I2C connectivity between RPI4 and pico

when I am trying to run the code in RPI4 an error raised:


Traceback (most recent call last):
File "/home/pi/Desktop/i2ctest.py", line 5, in <module>
bus.write_byte(0x41,12)
OSError: [Errno 121] Remote I/O error




and this is the code I used in RPi

import smbus
#import time
bus=smbus.SMBus(1)
#time.sleep(1)
bus.write_byte(0x41,12)
bus.write_byte(0x41,15)


I got another code in pico as well.


It would be so great if anyone help me with that.

Thanks

Hello

I do not have much experience using I2C on the pico. It may be worth posting your message on the official raspberry pi forum at https://forums.raspberrypi.com/viewforum.php?f=144
