Raj has been working on Netduino tutorials and so latest one is here. It’s about interfacing eight digit 7 segment LED display to Netduino. LED displays are driven using MAX7219 LED driver chip which accepts data via SPI interface. So this is all about sending SPI data from Netduino.
Netduino is a bit different from Arduino, because it is programmed using .NET framework. If you are comfortable with this platform, then it is really easy to get it working. Tutorial goes through several methods of running display. Take a look and you might find that works for you.
Netduino is a great development board with AT91SAM Arm microcontroller. It has more power than Arduino and can be programmed using .NET platform. No matter what microcontroller or platform we are using, we need some sort feedback in order to know what device is doing, and what data it displaying. LCD is a first choice in more complex projects. It can display multiple types of information in several lines. Embedded-lab briefly takes us through Netduino interfacing to LCD tutorial.
LCD is based on popular HD44780 controller. It is probably most common interface among textual LCD’s. And basically majority of libraries found on internet are written exactly for it. In this example LCD is connected using 4-bit interface. Code is pretty well explained so it can be easily adapted for new projects.
