This project stationery is designed to get you up and running
quickly with CodeWarrior for MC9S08QG8.
It is set up for the selected CPU and target connection,
but can be easily modified.
Sample code for the following language(s) is at your disposal:
- C
The wizard has prepared CodeWarrior target(s) with the connection methods of
your choice:
- P&E FCS:
This interface/target is prepared to use the FCS (Full Chip Simulation)
from P&E. Note that you can switch to hardware debugging in a seamless way,
using the menu PEDebug > Mode in the debugger.
- P&E ICD:
This interface/target is prepared to use the ICD (In-Circuit
Debugging/Programming) from P&E. Note that you can switch to simulation in
a seamless way, using the menu PEDebug > Mode in the debugger. Depending on
your hardware type, you will need to configure the communication settings
(class of device, baud rate, etc).
Please consult your hardware documentation for additional details.
- Freescale Serial Monitor:
This interface/target connects to the on-chip Freescale serial monitor.
This monitor uses on-chip resources and the SCI. See Freescale application
note AN2140 for details.
The debugger is using GDI (Generic Debugging Interface) to connect to the
serial monitor. Using the on-chip DBG module of HCS08 devices,
trace is supported as well. You can load the trace component
using the menu Component > Open in the debugger.
- SofTec:
This target interface connects to any of the USB-based SofTec Microsystems tools for HC(S)08.
For the HC08 derivatives, when using inDART-HC08 (MON08 protocol based connection):
-----------------------------------------------------------------------------------
If your hardware supports stopping the application while running,
an additional interrupt service routine is required for the IRQ vector.
Please see "Stop Command Handling" section in inDART-HC08 In-Circuit Debugger/Programmer
for Freescale HC08 Family FLASH Devices User Manual from SofTec for further details.
Additional connections can be chosen in the simulator/debugger,
use the menu Component > Set Target.
//------------------------------------------------------------------------
// Getting Started
//------------------------------------------------------------------------
To build/debug your project, use the menu Project > Debug or press F5.
This will open the simulator/debugger.
Press again F5 in the debugger (or menu Run > Start/Continue) to start
the application. The menu Run > Halt or F6 stops the application.
In the debugger menu Component > Open you can load additional components.

// Project structure
//------------------------------------------------------------------------
The project generated contains various files/folders:
- readme.txt: this file
- Sources: folder with the application source code
- Startup Code: C/C++ startup code (initializing stack pointer and doing
global variable initialization). If you want to only do stack pointer
initialization, add -D__ONLY_INIT_SP to the compiler command line.- Prm:
- burner.bbl file to generate S-Records
- the linker .prm file
- the .map file generated by the linker
- Libs: needed library files (ANSI, derivative header/implementation files)
- Debugger Project File: contains a .ini file for the debugger for each
connection
- Debugger Cmd Files: contains sub-folders for each connection with command
files
//------------------------------------------------------------------------
// Adding your own code
//------------------------------------------------------------------------
Once everything is working as expected, you can begin adding your own code
to the project. Keep in mind that we provide this as an example of how to
get up and running quickly with CodeWarrior. There are certainly other
ways to handle interrupts and set up your linker command file. Feel free
to modify any of the source provided.
//------------------------------------------------------------------------
// Simulator/Debugger: Additional components
//------------------------------------------------------------------------
In the simulator/debugger, you can load additional components. Try the menu
Component > Open.
