Hey everyone,
This is my debut post here, so if anything doesn't align with the forum's norms, please let me know.
I've been encountering some issues with my I2C setup. Initially, everything was running smoothly, but after introducing a new component (MCP23017), the I2C functionality suddenly ceased.
Running i2cdetect -y 1 returns:
and monitoring /var/log/syslog with tail -f yields:
It seems like I'm getting consistent timeouts with the I2C transfer.
Any thoughts on why it initially worked but then ceased functioning, and any suggestions on how to troubleshoot and resolve this hiccup? Thanks in advance!
