Keep 74HC595 outputs disabled through MCU boot, define both clock lines, shift a known byte, latch it, then pull OE low.
74HC595 Outputs Glitch at Startup? Hold OE High Before Latching Data Read More
A buck converter can regulate at idle and sag under load when cable, battery and switch resistance consume its dropout margin. Measure VIN and VOUT together.

NVIDIA’s Open Agent Safety Platform pairs OpenShell’s kernel-enforced sandbox with a BlueField-4 Sentry monitor outside the host CPU and GPU.
NVIDIA Splits AI-Agent Safety Between OpenShell and BlueField-4 Read More
A4988 VREF depends on the carrier’s sense resistors, and a full-step coil-current measurement reads only about 70% of the configured current limit.
Set A4988 Current Limit From VREF, Sense Resistors and Full-Step Current Read More
PCF8574 pins have no direction register. A pin becomes usable as an input when its output latch holds 1, and a port read also clears its interrupt condition.
PCF8574 Inputs: Write High First, Then Read the Port Read More
The unofficial Blender for Android Alpha 4 build adds Turnip driver options, working audio, CPU denoising and several graphics fixes—but still carries device-specific failures.
