Hi everyone, is it fine to call the callback function to increment the timestampgesture only once?
I read that I should call it before ProcessWidget and also before DecodeWidgetGesture, should I call it again or could just once at the beginning be enough? Maybe right before Process_Widget? Is it better 1ms or 2ms
PS, the code implements also BLE communication
This is the code, thank you
if(enbaleTrackpad != 0u)
{
/* Sets up a callback function using sysTick timer isr, the callback function
is part of the CySysTickSetCallback API */
//CALL INCREMENT TIMESTAMP CALLBACK ONLY HERE
CapSense_dsRam.timestampInterval = 1u;
///// // CapSense_dsRam.timestampInterval = 2u;
CySysTickStart();
CySysTickSetCallback(0u, CapSense_IncrementGestureTimestamp);
////// // CapSense_SetGestureTimestamp(2u);
/* Start scanning all enabled sensors */
CapSense_SetupWidget(CapSense_TOUCHPAD0_WDGT_ID);
CapSense_Scan();
/* Wait for scanning to complete */
while(CapSense_IsBusy() != 0u)
{
}
////IS IT BETTER TO INCREMENT THE TIMESTAMP GESTURE HERE????
/////// // CapSense_IncrementGestureTimestamp ();
CapSense_ProcessWidget(CapSense_TOUCHPAD0_WDGT_ID);
/* Process the trackpad X,Y and the gestures */
if(CyBle_GattGetBusStatus() == CYBLE_STACK_STATE_FREE)
{
/////////IS IT BETTER TO INCREMENT THE TIMESTAMP GESTURE HERE????
////// // CapSense_SetGestureTimestamp(2u);
///// //CapSense_IncrementGestureTimestamp ();
/* Get the gesture */
gestureID = CapSense_DecodeWidgetGestures(CapSense_TOUCHPAD0_WDGT_ID);
/* Get delta X and delta Y */
touchPos[0]=CapSense_TOUCHPAD0_POS_X_DELTA_VALUE;
touchPos[1]=CapSense_TOUCHPAD0_POS_Y_DELTA_VALUE;
touch=CapSense_IsWidgetActive(CapSense_TOUCHPAD0_WDGT_ID);
/* simulate a mouse */
if ((touch != 0u)||(gestureID != 0u))
{
SimulateMouse(gestureID);
}
else
{
touchPos[0] = 0u;
touchPos[1] = 0u;
SimulateMouse(gestureID);
}
Solved! Go to Solution.

Hi dabo_4430311,
Refer to the CapSense_IncrementGestureTimestamp explanation in the CapSense component datasheet for the different methods of updating the timestamp.
https://www.cypress.com/documentation/component-datasheets/psoc-4-capacitive-sensing-capsense
Since you are registering a periodic callback to update the timestamp using Systick, it is not required to call this func in the application.
Please refer to the CE224820 – PSoC 4 CapSense Slider with Gestures that implements all the three techniques to update timestamp.
