Callback

This section describes the CSDADC Callback Function.

A callback allows a user to execute custom code called from the CSDADC middleware when the current cycle of enabled channel conversion finishes in the continuous mode.

To assign a user's function to this callback presented in the middleware, do the following:

• Assign a pointer to the variable of the cy_stc_csdadc_context_t type as below:

  cy_stc_csdadc_context_t * ptrCxt = &My_CSDADC_context;

• Write the callback function implementation (in any user file) using the following function prototype:

  void CallbackFunction((void *) ptrCxt);

• Assign the function to the CSDADC context structure by using the function Cy_CSDADC_RegisterCallback();
• Use the Cy_CSDADC_UnRegisterCallback() API to un-register the callback function that was previously assigned.
