ESP32: When Is A P4 A P4, But Not The P4 You Thought It Was

Me he picado con el ESP32-P4… y se me ha ido de las manos 😅
DOOM corriendo en un ESP32-P4.
Y lo curioso: no había ningún port de DOOM para ESP32-P4 (aunque sí de Quake)…

Me he basado en DOOM GENERIC
La idea es muy directa:
implementas unos hooks y conectas el motor a tu hardware
Render, input y timing. Sin más.
Para el input he usado usb_host_hid:
teclado y ratón USB directamente al ESP32-P4.
Y para el vídeo… chiquito.wad 😏

Estoy trasteando con gráficos en el ESP32-P4 y he montado el típico efecto de agua 2D (ondas + refracción) usando MIPI DSI.

Lo curioso ha sido el cuello de botella:

Con la física en los 2 cores

Usando el PPA para escalar

Todo bien… pero la clave es la memoria.

En SRAM interna va a unos 84 FPS 🚀
En PSRAM cae a ~30 FPS

Some good news for #Tanmatsu owners and others who partake of the #BadgeLife - #MicroPython now kinda sorta works on the #ESP32P4  

In case of interest, here's an MP fork with my lazyweb "port" where the only changes are basically copying the ESP-IDF settings for the Tanmatsu over into the MP source tree as a new board:

Disclaimer: On the great Copilot In The Cloud because there are too many moving parts to cleanly slurp over elsewhere
