DOOM! on the #emfcamp TiDAL badge

• esp32-doom

  13 177 0.0 C++

  A proof-of-concept port of PrBoom to the ESP32. Needs psram hardware.

  

There is a port of DOOM for an ESP32, proving that it can be done, however I have added additional constraints on myself as follows:

• doomgeneric

  19 1,081 6.9 C

  Easily portable doom

I also had to choose a starting version of DOOM, with an emphasis on portability. This turned out to be the easy bit, enter DOOM generic, which happily compiled and ran first time on my Linux desktop ;)

• InfluxDB

  www.influxdata.com featured

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• MicroPython

  197 18,387 9.8 C

  MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems

  

Fix Multiple, bugs in Micropython.

• esp-idf

  245 12,508 10.0 C

  Espressif IoT Development Framework. Official development framework for Espressif SoCs.

  

After a great deal of reading through technical manuals and rummaging in the code, creating the romread test application and generally poking at (and crashing) my device, I understand how the memory manager works, what I can and cannot touch and in theory how I can memory map and execute another app within micropython. There is also a fair amount of investigation into the Micropython memory layout, see memstuff folder! Thus is born doomloader.mpy a short and separate Micropython module that pokes at the MMU to load an OTA app into Micropython-safe address space. It works :D, next step..

• nanoprintf

  5 575 5.5 C++

  The smallest public printf implementation for its feature set.

It turns out that DOOM expects a little more POSIX compliance from it's C library than Micropython provides, in particular the printf implementation is lacking many features. The good part is that because I'm building an entirely separate binary application, I can use someone elses printf, and finally, after a lot of pain, it runs!

• st7789_mpy

  3 483 5.1 Python

  Fast MicroPython driver for ST7789 display module written in C

The colour being mangled turns out to be an endian difference between the MPU and the display device, easily determined by looking at the code for the display driver, which byte-swaps everything when drawing into the device, unless it's blitting a buffer, when it assumes it's already swapped. Fixed.

• doom-tidal

  1 8 0.0 C

  Discontinued DOOM for the #emfcamp TiDAL badge :)

To horribly mis-quote another of my favourite games come get some baby!
