Touch Pads (EBM013) component

This board provides two touch areas for use with capacitive sensing. Hence two digital touch switches can be implemented. This component directly interfaces with the EBM013 Sensors board.

Examples

Sample program using the EBM013 - Touch Pads sensor.

Sensors are first calibrated and then can be read as digital switches

EBM013 Example

Downloadable macro reference

GetTouchValue

Samples the touch sensor ADC value and returns it

Always samples both channels, but only returns the chosen channel

Parameters

BOOL Switch

Select Switch. Switch 1 = 0, Switch 2 = 1

Return value

UINT

GetTouchPressed

Returns non-zero if touch detected

Parameters

BOOL Switch

Switch 1 = 0, Switch 2 = 1

UINT OffValue

BYTE Threshold

Provide the threshold value for the pad to be considered touched

Return value

BOOL : Returns true if the operation is a success, else false
