I wanted to try out myself how well solar energy really works. Toward this aim I built a solar collector system for waterheating. A small boiler with a heat exchanger is used for heat storage and a ordinary heating pump for the water circulation. Temperature is measured at the collector, at the entrance and outlet of the heat exchanger and inside the heat storage boiler. As a controller for the pump I used an MSP430 launchpad. There were several problems I had to solve. First, temperature must be measured with a resolution of at least 1 degree. My preferred temperature sen

This is a C++ template for the Nokia 5100 that uses software SPI. Inspired by Rickta59's GPIO template Using C++ templates allow the compiler to make decisions at compile time that would normally occur (repeatedly) at execution time. This results in smaller and faster code. They also are type safe and compatible with source level debugging (unlike macros). Software SPI is used to make the code very portable to the entire MSP430 family and allow flexible pin assignment. Four wiring schemes are supported. This is the syntax for creating an instance of the template. Nokia5

This is my attempt for a basic library to control an 16x2 or more LCD display using 6 PIN and controling the hd44780 in 4bit mode. Main .c: http://dl.dropbox.com/u/13477186/MSP430 ... _example.c Library .h: http://dl.dropbox.com/u/13477186/MSP430 ... _hd44780.h Library .c: http://dl.dropbox.com/u/13477186/MSP430 ... _hd44780.c Makefile : http://dl.dropbox.com/u/13477186/MSP430 ... 0/Makefile It working great for my needs so far. Work on my 4 line display too.. My next step will be to make this library support the use of an 595 for 3 pin operation. I would also like some way

NOTE: This was built using IAR, for an msp430 with the USI peripheral. It will need editing to work on USCI peripherals or if compiled in CCS or GCC. Updated 12/12/12: http://forum.43oh.com/topic/126-i2c-explorer/?p=25918 I like i2c, and have one main project I want to create based on turning a scrolling led display into a computer/net/micro controller accessible one (it has an i2c eeprom, and its original mc is still in use). Having gotten the launchpad, it was one step closer to completion. The next step was getting i2c protocol working and such. With the builtin USI of the launchpad,
