Development of DCC Control Unit

My DCC control unit uses an LMD18200T integrated circuit as a DCC-line driver and a microcomputer PIC18F252. It communicates with a PC (Windows, Linux, macOS, OS X, Android, iOS, ...) through a MIDI connection. The unit contains also an LCD display, buttons and a rotary encoder (knob) for controlling the railway without PC.

Advantage of using the MIDI communication is that MIDI-support is available for all common operating systems including Android and iOS. Only you need is a MIDI interface (USB to MIDI) and an appropriate driver. Through sending of simple MIDI commands it is possible to control or even programm whole model railway.

Original resistors have been replaced by 4.7 kOhm SMD resistors due to lower brightness.
