I'm building a DCC Command Station that meets the NMRA standards. It's a compact system that includes a booster, 16x2 or 20x4 LCD, membrane keypad and a couple switches.

I making 2 models. One is based in the 16F88 microprocessor that allows control of 4 locomotives using a 16 button keypad.  Each row is speed up, speed down, direction and function 0 on/off. One of the locos can also be controlled by analog.

The 2nd model uses the 16F1938 microprocessor where the 4 locos can be controlled by analog control. Firmware can be updated over the internet using a USB connection to your PC.

Both models include turnout routing from A to Z. Adding turnouts to routes are limited to the amount of memory available on the chip.

I've built a few prototype Printed Circuit Boards for the 1st model and all has been working fine for the past 2 years. Now I'm having some of the version 2 (16F1938) PCB's made professionally. Hopefully I'll receive them in 2 weeks.

I'll post some photos if anyone is interested.

John.
