Train Controller Project

Overview

A Realistic DCC Throttle Inspired by Epoch IV.

This project aims to replicate the functionality and aesthetics of a classic train engine cabin commonly used during the Epoch IV era of model railroading. By combining modern microcontroller capabilities with a nostalgic design, the Train Controller provides an authentic and immersive experience for model train enthusiasts. More info here...

The Train Controller Software Project is a modular and thread-safe UI system designed for the Raspberry Pi Pico using the Arduino framework provided by the earlephilhower core. It leverages the TFT_eSPI library for driving TFT displays and includes enhancements to make the library thread-safe in an RTOS environment.

Features

1. Raspberry Pi Pico Support:

   • Built using the earlephilhower Arduino core.

2. TFT_eSPI Integration:

   • Uses the TFT_eSPI library for high-performance TFT display rendering.
   • Configured for an ST7789 driver with 240x320 resolution.

3. RTOS Use:

   • Runs on FreeRTOS, enabling multitasking.

4. Dynamic UI System:

   • A PageManager handles navigation between different UI pages.
   • Includes a ThreadSafeTFT wrapper to make TFT_eSPI thread-safe using a FreeRTOS semaphore.
