 Python code for talking to HD44780 compatible character based dot matrix LCDs.
 
+## Other ports

 This code is synchronous. Peter Hinch put together an async driver for
 the HD77480 over [here](https://github.com/peterhinch/micropython-async/tree/master/HD44780).
 
+This library is based off of a C version that I wrote, which can be found
+[here](https://github.com/dhylands/projects/blob/master/common/lcd-api.c)
+(also look for files in the same directory which start with lcd).
+
+Nic created a C# port of this library which can be found [here](https://github.com/OfItselfSo/CS_LCD).

+## Communicating with the LCD
+
 You can communicate with the LCDs using either 4 or 8 GPIO pins.
 
 Alternatively, the I2C classes implement 8-bit GPIO expander boards

 The photo shows Orange connected to P9-5. I discovered that P9-7 is controlled
 by the onboard voltage regulators, so when you do a "sudo poweroff" then
 SYS_5V drops to 0v when the BBB is powered off. P9-5 (VDD_5V) remains at
 5v after the BBB is powered off.
