Chapter 7. Project Files

7.1. Standard Project Files

The RSK tutorials are configured so that it is possible to provide the same tutorial code on multiple RSK products. This allows the

evaluation of the different processor cores using equivalent code. To achieve this, the following files are common between all device cores

and Tool-chains.

Each of the tutorial files has detailed comment text describing the function of each code entry. Please refer to the source code for greater

detail on the purpose and operation of the compiler specific details.

7.1.1. Initialisation code (resetprg.c / resetprg.h)

This is the entry point of the main tutorial code.

Initialisation of the variables used in the C compilers and initialisation of stack pointers are completed in the _INITSCT function for the H8

and SH compilers. The call to HardwareSetup() will initialise the device hardware and peripherals ready for the tutorial software.

The call to ‘main()’ will start the main demonstration code.

7.1.2. Board initialisation code (hwsetup.c / hwsetup.h)

There are four common stages to the configuration of the microcontroller device. The code to demonstrate this is therefore split into four

functions. Each function is written specifically for the device supported. The function calls are shown below.
