LSM6DSOX FIFO Overruns: Set the Watermark From Your Drain Time

October 16, 2026October 16, 2026 - by TVG Editorial Team - Leave a Comment

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.

INA260 Alert Arrives Late? Calculate the Averaging Delay

October 15, 2026October 15, 2026 - by TVG Editorial Team - Leave a Comment

INA260 averaging reduces noise but multiplies the time before a current, voltage or power alert can react. Calculate the conversion window before debugging firmware.

TCS34725 Color Readings Drift? Control Gain, Exposure and Illumination

October 14, 2026October 14, 2026 - by TVG Editorial Team - Leave a Comment

Repeatable TCS34725 readings depend on fixed illumination, sensor geometry, gain and integration time—not just converting raw channels to an RGB color.

NAU7802 Load-Cell Setup: Calibrate After Gain and Rate Changes

October 13, 2026October 13, 2026 - by TVG Editorial Team - Leave a Comment

A reliable NAU7802 setup treats gain, sample rate and calibration as linked controls, then checks CALS and CAL_ERR before using load-cell readings.

SHT31 Heater Checks: Prove Sensor Response Without Treating Heat as Humidity Data

October 12, 2026October 12, 2026 - by TVG Editorial Team - Leave a Comment

The SHT31’s internal heater is a plausibility-check tool, not a condensation cure or normal measurement mode. Use commands 0x306D and 0x3066 with status bit 13 and label heated samples invalid.

BME280 Forced Mode: Wait for Conversion Instead of Reading on a Guess

October 11, 2026October 11, 2026 - by TVG Editorial Team - Leave a Comment

A robust BME280 forced-mode loop starts one conversion, waits for the status register’s measuring bit to clear, then reads the compensated result. Fixed delays hide oversampling-dependent timing.

APDS9960 Gesture Interrupts: Drain the FIFO Before Clearing the Event

October 9, 2026October 9, 2026 - by TVG Editorial Team - Leave a Comment

APDS9960 gesture events can repeat or disappear when firmware clears the interrupt without consuming the gesture FIFO. Read status, drain valid datasets, then finish the engine sequence.

AS5600 Angle Jumps? Check Magnet Status Before Filtering the Data

October 8, 2026October 8, 2026 - by TVG Editorial Team - Leave a Comment

AS5600 angle problems often start with magnet geometry, not software noise: check detection, too-weak and too-strong status before filtering 12-bit readings.

ADXL345 Tap Detection: Convert Threshold and Timing Registers First

October 7, 2026October 7, 2026 - by TVG Editorial Team - Leave a Comment

ADXL345 tap detection uses scaled threshold, duration, latency and window registers plus axis enables and interrupt mapping; raw register values are not g or milliseconds.

TSL2591 Saturation: Lower Gain Before Trusting the Lux Reading

October 6, 2026October 6, 2026 - by TVG Editorial Team - Leave a Comment

The TSL2591 can span very dim to bright scenes, but gain and 100–600 ms integration time determine whether its full-spectrum or infrared channel saturates.

TVG Report infographic over a 3D-printing workbench highlighting first-layer, profile, and fit checks before adjusting and reprinting

You can lose an evening to a drifting first layer, a bad profile, or a part that prints cleanly and still does not fit. TVG Report looks past headline speeds to the checks, tradeoffs, and repair paths makers actually need. #3DPrinting

DS18B20 debugging infographic showing the 85.0°C power-on value, a three-wire probe, and checks for conversion, CRC, and power

A DS18B20 at exactly 85°C may be power-on data—not heat. Trust it after conversion completes and CRC passes. Our guide maps power mode and w1_therm checks.
