“However can it run Doom?” is greater than only a joke within the tech world. Additionally it is an honest litmus check for the computing energy of {hardware}. That check isn’t very related for contemporary computer systems, however it’s nonetheless price asking when discussing microcontrollers. Microcontrollers differ in dramatically in processing energy and reminiscence, with fashions to go well with each utility. However you probably have an Arduino Nano ESP32 board, you possibly can run Doom as Naveen Kumar has confirmed.

The Nano ESP32 is a small IoT growth board for the ESP32-S3 microcontroller, that includes Wi-Fi® and Bluetooth® connectivity. It additionally has a comparatively excessive clock pace and numerous reminiscence: 240MHz and 512kB SRAM, respectively. That also isn’t sufficient to fulfill the necessities of the unique Doom launch, which wanted much more RAM. However Kumar demonstrates the usage of an MCU-friendly port that runs nicely on this extra restricted {hardware}.

Wish to give it a strive your self? You’ll want the Nano ESP32, an Adafruit 2.8″ TFT LCD defend, an M5Stack joystick, a Seeed Studio Grove twin button module, a breadboard, and a few jumper wires to create a easy handheld console. You’ll need to compile and flash the Retro-Go firmware, which was designed particularly for operating video games like Doom on ESP32-based gadgets. You possibly can then load the specialised WAD (The place’s All of the Information) information.

Kumar studies a mean body price at a 320×240 decision, which could be very playable.
