In order to generate and test software, the Keil compiler and the Signum in-circuit emulator (ICE) must be installed per
the instructions in section 4. The include files and header files must also be present on the development PC. Typically,
a design session consists of the following steps:
The 71M652X software architecture is partitioned into three separate layers:
Figure 2-1: shows the partitions of each software component. As illustrated, there are many different designs an
application can develop depending on its usage. Section 5 describes in more detail the functions within each
component.

SOFTWARE ARCHITECTURE
The lowest level is the device or hardware layer, i.e. the layer that directly communicates with the discrete
functional blocks of the chip and the peripheral components (“hardware”), such as serial interfaces, AFE, LCD
etc.
The second layer consists of buffers needed for some functions.
The third layer is the application layer. This layer is partially implemented by the Demo Code for evaluation
purposes, but extensions and enhancements can be added by the application software developer to design
suitable electronic power meter applications.
Editing C source code using µVision2
Compiling the source code using the Keil compiler
Modifying the source code and recompiling until all compiler error messages are resolved
Using the assembler and linker to generate executable code
Downloading the executable code to the ICE
Executing the code and watching its effects on the target
