The LPC812 MAX Experiment Kit has been created as a guided tour to learn embedded programming with the mbed framework and the NXP’s LPC800 microcontroller family with Cortex-M0+ core. The experiments are performed on a breadboard for maximum flexibility and ease of use.

The component kit can be bought from Embedded Artists. In order to perform the experiments an LPC812 MAX board is also required. This board must be bought separately.

All experiments are based on the LPC812 MAX board, but the experiments can easily be ported to other mbed platforms.

This page is the starting page for all documentation about the experiments.

Getting Started

As a first step it is recommended to read the Getting Started Tour. It contains information about how to work with the on-line compiler and how to download and execute the code.

Experiments

It is recommended to follow the order of the experiments. They have been compiled to give you the best learning curve. There are often multiple small steps in each experiments and they build upon each other. Where appropriate, shorter theoretical discussions have been added.

These are the experiments:

1. Digital Outputs
2. Digital Inputs
3. Control Multiple LEDs
4. Work with a Serial Bus - UART
5. Analog Input
6. Pulse Width Modulation
7. 7-Segment Display
8. Work with a Serial Bus - SPI
9. Interrupts
10. Work with a Serial Bus - I²C
11. Expansion Port - XBee and GPS
12. Character LCD
13. Stepping Motor

Component Kit

In this section we will take a closer look at the different components included in the kit.

Note that all components are not used in the experiments, for example the diodes, the NPN transistors and the temperature sensor. These components are left as an exercise to use in own experiments.

The table below contains photos and a description of all components in order to simplify identification. Note that photos are only typical in the sense that they illustrate the components typical visual appearance. Exact appearance can differ for the components in the kit that you have received. The number of components shown in a picture can also differ from delivered quantity.

Most components are specified with a Digikey or Mouser equivalent. If a component gets damaged, a new one can typically be ordered from Digikey, Mouser or any preferred component distributor. The Digikey/Mouser number is just to get the key data of the component. The actual components in the component kit might very well be of different brands.
