TI-DCC

Is a z80 ASM NMRA-DCC throttle implementation for the TI-84 Plus C Silver Edition.

Features

• Custom DCC throttle interface.
• FL-F26 Function support with momentary/locking functions
• 14/28/128 step speed modes
• 2 Digit and 4 Digit addressing

ToDo

• Analog/DC throttle mode - To be implmented.
• Verify 14/128 step speed modes
• Verify Long addresses work
• Finish Reccomended schematic

Requirements

Building

• Python 2.* and the python launcher. (comes with py3...)
• Pillow

Use

• Motor driver - A motor driver/H-bridge and circuit used to generate the on rail signals for the train.
• Power supply for the motor driver. Voltage is based off of the scale train you plan on controlling. See the NMRA Standards linked at the bottom of this readme

Known good motor drivers

• LMD18200 using this circuit MiniDCC

Installation

1. run _buildclean.bat
2. Transfer application to calculator using TI-Connect or TILP
