Structure of the source code
The components of an application in TWELITE NET are as follows
  • Definitions of callback functions and modules: mandatory definitions, to be written in the main file.
  • User-defined event processing functions: these are written as required. These functions are designed to work with state machines.
  • User-defined functions: These are other processing functions that are application-specific code.
The main files are described below.

Main file

In the TWENET API, the main file contains the following definition.
  • Module declaration (mandate in the Main file)
  • Required header file includes
  • Callback functions
You can also put other procedure in files other than the main file.
The TWENTE API does not have a main() function as is common in C language processors. The first function to be called is the cbAppColdStart() function.

Module definition and inclusion of required header files

Define functions and memory to be determined statically at compile time in order to minimise build binary and runtime memory.
Write the definition of the module usage declaration before cbAppColdStart() and initialize it by calling the ToCoNet_REG_MOD_ALL() macro in cbAppColdStart().
For header files, "ToCoNet.h" and "ToCoNet_mod_prototype.h" are required.
// Select Modules (define befor include "ToCoNet.h")
// Includes
#include "ToCoNet.h"
#include "ToCoNet_mod_prototype.h"
void cbAppColdStart(bool_t bStart) {
if (!bStart) {
// Module Registration
} else {

Callback functions

The callback functions should always be defined in the source code.
