Calculate the DRV8871 ILIM resistor from the datasheet range, understand its 25 µs chop cycle, and separate current regulation from thermal and overcurrent faults.
Set DRV8871 Current Limit Without Confusing Peak and Continuous Current Read More
Measure PCF8523 drift in ppm, convert it to the signed offset register, and rule out oscillator-stop and backup-battery faults before calibration.
Calibrate PCF8523 RTC Drift and Check Backup Failures First Read More
GitHub’s open source license compliance is now generally available, adding enterprise license policy checks to pull-request rulesets before merge.
GitHub License Compliance Goes GA as a Merge-Time Ruleset Read More
LSM6DSOX FIFO watermarks should leave enough headroom for interrupt latency and bus drain time. Size the batch from the active sensor rates, then watch overrun status.
LSM6DSOX FIFO Overruns: Set the Watermark From Your Drain Time Read More
A MAX31865 converts an RTD-to-reference resistance ratio. The wrong reference value or lead-wire mode creates a believable but biased temperature.
MAX31865 RTD Readings Wrong? Check Reference Resistance and Lead Wiring Read More
GitHub Agentic Autofix can investigate up to 25 code-scanning alerts, rerun CodeQL and open a draft pull request, but its validation does not cover every alert source.
GitHub Agentic Autofix Goes GA, but Validation Still Has Boundaries Read More
INA260 averaging reduces noise but multiplies the time before a current, voltage or power alert can react. Calculate the conversion window before debugging firmware.
INA260 Alert Arrives Late? Calculate the Averaging Delay Read More
MCP9808 alert behavior depends on open-drain wiring, threshold mode, hysteresis and conversion time—not only the programmed temperature limit.
MCP9808 Alert Pin Chatter? Match Hysteresis to Conversion Time Read More
GitHub Actions workflow lockfiles keep readable tags in YAML while executing recorded commits for direct, transitive and reusable-workflow dependencies.
GitHub Actions Workflow Lockfiles Pin Direct and Transitive Dependencies Read More
Repeatable TCS34725 readings depend on fixed illumination, sensor geometry, gain and integration time—not just converting raw channels to an RGB color.
TCS34725 Color Readings Drift? Control Gain, Exposure and Illumination Read More
