I2C debugging — bus hangs, NACK storms, and clock stretching timeouts
I2C looks simple until the bus hangs and no amount of resets fixes it. Clock stretching violations, address conflicts, and pull-up resistor issues that only show up at temperature.
Why generic AI tools miss this
Generic AI code review and debugging tools are trained primarily on web and backend code. I2C Debugging requires understanding of hardware-software interaction at the register level — something that represents a tiny fraction of any general model's training data.
The danger is that a generic tool will give you advice that looks correct but misses the hardware-specific nuance. For i2c debugging, the nuance is everything — a subtly wrong answer compiles, links, and flashes successfully, then fails in the field.
Affected MCU families
I2C Debugging is particularly relevant to these platforms. Each has its own variant of the problem and its own mitigation strategy.
How usefirmware helps
Our AI tools are purpose-built for firmware. They understand i2c debugging at the register level and can catch it during:
