QDebug Interface: Allows Live streaming of Touch data to QTouch Analyzer.
The default SPI connection between Xplained Pro Kit and User Board is:
-
SPI_BB_SS - B31
-
SPI_BB_SCK - B23
-
SPI_BB_MOSI -B22
-
SPI_BB_MISO -B16
Rules & Guidelines:
-
Same port pin cannot be used more than once.
Tuning Parameters:
-
Enable noise counter measure: This setting sets up the PTC for pre-scaler auto tuning along with frequency hop acquisition mode providing best noise performance.Disabling noise counter measure sets up the PTC for series resistor auto tuning along with frequency none acquisition mode resulting in least power consumption.
-
Filter Level: The filter Level setting controls the number of samples taken to resolve each acquisition. A higher filter level setting provides improved signal to noise ratio under noisy conditions,while increasing the total time for measurement resulting in increased power consumption and response time.
-
Auto OS: Auto oversample controls the automatic oversampling of sensor channels when unstable signals are detected with the default setting of ‘Filter level’. Enabling Auto oversample results in 'Filter level' x 'Auto Oversample' number of samples taken on the corresponding sensor channel when an unstable signal is observed. In a case where ‘Filter level’ is set to 4 and Auto Oversample’is set to 8, 4 oversamples are taken with stable signal values and 16 oversamples are taken when unstable signal is detected.
