A custom STM32-based programmable gamepad with firmware-defined input logic
Overview
Comet Gamepad is a custom-built plug-and-play device so you can get started with your favourite games in no time, focused on low-latency and deterministic input, it includes an integrated trackpad for enhanced control and interaction.
The design prioritizes:
- Deterministic input behavior
- Low-latency USB HID reporting
- Firmware-controlled mappings and modes
Hardware Specifications
- MCU: STM32G431CBU6
- Firmware: Custom STM32 Firmware
- Trackpad IC: Azoteq IQS 9150
Firmware Architecture
The gamepad firmware is written specifically for the STM32 platform and does not rely on higher-level keyboard frameworks.
All input processing, state tracking, and HID reports are implemented directly in firmware.
