    Question:

    When I use the SmartSense_EMCplus module together with a custom Rawdata Filter, the sensor gets stuck always.

     

    Answer:

    In PSoC® 1 CapSense® modules, sensor rawdata and baseline are always stored in waSnsResult[] and waSnsBaseline[] arrays. In general, both these arrays are updated after the InitializeBaselines() API is executed, but this is not true for SmartSense_EMC and SmartSense_EMCplus modules.

    In SmartSense_EMC and SmartSense_EMCplus modules, waSnsResult[] remains in an unassigned state until ScanSensor() (or ScanAllSensors()) functions are executed. Therefore, if you use a custom filter in your project, execute ScanSensor() (or ScanAllSensors()) functions once before initializing the filter.

    Correct code template is as follows:

         /****************************************/ 

               M8C_EnableGInt;

    CapSense_Start();

    CapSense_InitializeBaselines();

         CapSense_ScanAllSensors();

         Filter_Init(); // Initialize customize filter

         ……
