SPI Signals That Lie
When plausible bytes hide electrical or sequencing failure
Debouncing with Time and State
Not hope: explicit stability windows instead of ISR delays
RISC-V on a 10-Cent Chip
CH32V003 bring-up, UART echo, and 8 uA sleep
AVR Bare-Metal Blinking
Timer1, registers, and a 176-byte binary without Arduino
