HARMONIC INTERFERENCE by AK
===========================
ASSEMBLY 2026 SUMMER
===========================
Runtime: 2:51 - 171 s
Hardware Requirements:
Works on boards where PCB revision number is 2 or higher, pin GPIO_SD_B0_00 (SD CMD)
is used as PWM output and is fed to a basic RC-filter circuit with
an op-amp buffer to get a filtered analog output.
Simucube Link Wheel Module, PCB revision 2+
-> Works on unmodified hardware without sound, for sound PWM output needs to be soldered,
check video for correct pad
-> Can be flashed through 10-pin Tag-Connect pads using SWD
-> harmonic_interference__slwm_r2.hex
RT1064 evaluation board (MIMXRT1064-EVK), binary should work and wake up the LCD (not tested)
-> GPIO_SD_B0_00 (SD CMD) should be available on a pin header or through SD card slot
-> Official LCD for the evaluation board has smaller 480x272 resolution, needs to be
switched to a common 800x480 (4.3 or 5 in, eg. adafruit 40-pin TFT 800x480), uses common timings
-> Remove the SD card before running the program as it uses SD CMD pin for audio
-> Can be flashed with the integrated debugger on the evaluation board, or with external JLink etc.
-> harmonic_interference__1064-evk.hex
=============================
Specs:
- Board: Simucube Link Wheel Module, might also work on RT1064 evaluation
board with the correct .hex file
- RT1064, 4 MB flash / 1 MB RAM + 8 MB / 32 MB external
- 800x480 display resolution
- Custom self-made 4-channel (8-oscillator) software synth + tracker
- 2 oscillators + LFO per channel
- ADSR envelope, pitch bend velocity, basic LP/HP/BP filtering
- 44.1 kHz sample rate
- Output through one PWM output, 500+ kHz carrier
- MIDI data converted and stored as note track and timeline
- No samples used
=============================
Meet the Simucube Link Wheel Module: a display module
for sim racing wheels, featuring a custom PCB I
designed a couple of years ago.
I've wanted to submit an entry to the Real Wild compo
for years, and I finally have the perfect self-designed
platform to code on!
After porting DOOM to it (because of course), I decided
to push it as a demo platform. All code running straight
on the hardware, no RTOS.
