racketFrom Blocking to Cooperative: Replacing delay() with millis() on Arduino UNO
Learn how to replace blocking delay() calls with non‑blocking millis() timing on Arduino UNO, enabling concurrent tasks like LED blinking and serial printing. Includes a step‑by‑step example, overflow‑safe subtraction, trade‑offs, and verification steps.
Why delay() Eats Your Button Presses — and the millis() Pattern That Fixes It
delay() busy-waits and silently drops button presses and Serial data. Learn the rollover-safe millis() subtraction idiom with a blink-plus-button sketch, its jitter trade-offs, and when hardware timers win.
Replace Arduino delay() with Non-Blocking millis() Timing
Convert blocking delay() calls to non-blocking millis() scheduling so Arduino AVR sketches stay responsive to buttons, serial, and sensors while running periodic tasks.
Stop Using delay(): Mastering Non-blocking Timing in Arduino
Stop freezing your Arduino projects. Learn how to replace blocking delay() calls with millis() to handle multiple tasks like blinking LEDs and reading sensors simultaneously.
Arduino delay() vs millis(): Non-Blocking Scheduling in Practice
delay() freezes the whole sketch, not just one task. Here is how millis()-based elapsed-time checks let a blink pattern and a debounced button run together — and what that costs.
Vert.x: When to Use Worker Verticles vs. Non‑Blocking APIs for Blocking Operations
Decide quickly whether to wrap blocking code in a worker verticle or refactor to a non‑blocking API. A concise table, trade‑offs, and a concrete example show how to keep your Vert.x app responsive.
vertxSDLNet_TCP_Accept non-blocking contract for cross-platform servers
SDLNet_TCP_Accept non-blocking contract for cross-platform servers SDL_net 2.0 specifies that SDLNet_TCP_Accept() should return NULL and set errno to EWOULDBLOCK when the listening socket is placed in non-blocking mode via SDLNet_TCP_SetNonblocking(). However, the implementation varies across Windows, Linux, and macOS: some platforms return immediately, whil
