Optional Jumpers For Various VDD And VSS
The DEMOEM provides 5 jumpers, J19 through J23, for different VDD and
VSS connections on the bottom of the board. By default, they are not
populated and are shorted correspondingly with zero-ohm resistors in parallel,
except J21 which is populated. The user may take off the zero-ohm resistor
and install a corresponding jumper.

DEMOEM CODE DEVELOPMENT SOFTWARE
The DEMOEM includes P&E’s Embedded Multilink circuitry, so no external
hardware BDM tool is needed to debug and program the DEMOEM. A user
only needs to connect the DEMOEM to their PC to start developing code for it.
The DEMOEM package comes with an evaluation edition of Freescale’s
CodeWarrior studio. In addition, P&E’s evaluation software for HCS08 and
ColdFire® V1 is available in the DEMOEM Resources section of the Getting
Started DVD, or online at www.pemicro.com. A user may use either
CodeWarrior or P&E software tools to develop code for the DEMOEM.

Using CodeWarrior With The DEMOEM
The CodeWarrior for Microcontrollers studio supports Freescale’s HCS08 and
ColdFire V1 devices. It offers C, C++, and assembly-level support, and
provides debugging capabilities based on P&E’s debug and programming
technologies.
A programming or debug session with the project-based CodeWarrior IDE
may be launched by double-clicking on the project name (the format is
projectname.mcp
) from your file storage. The DEMOEM tutorials, FAQs, and
quick start guide are easy to follow and will allow you use pre-built templates
