Multi Touch Kit Arduino Library
This is an Arduino library for Multi Touch Kit. For more information on the project and tutorial, visit our website.
Installing
Download the library as a zip folder and install it as described here: https://www.arduino.cc/en/Guide/Libraries ("Importing a .zip Library")
Setup
At first, make the Serial Connection (https://www.arduino.cc/reference/en/language/functions/communication/serial/).
Then, add the MultiTouchKit object (MultiTouchKit mtk;),
call mtk.setup_sensor(int rx, int tx, int* muxPins, bool raw_data, int threshold); in setup(),
and then mtk.read() in loop().
If you need raw values, set raw_data to true. If you want to get access to touch up/down values, set raw_data to false.
Documentation
setupSensor(int rx, int tx, int* muxPins, bool raw_data, int threshold);
rx and tx define the number of receiver and transmitter lines,
int* muxPins defines the digital pins for the multiplexer,
bool raw_data determines to send the raw values (raw_data==true) or touch up/down events (raw_data==false).
int threshold is the threshold for the touch recognition, every value above the threshold will be detected as touch if :raw_data==false
read() function will send the raw values or true/false (depending on the selected mode) for each intersection via Serial port.
The output of read() function will be lines of integer values, separated by commas when 'raw_values = true'. The first number of each line is the number of the activated TX line and the following numbers are the values measured at the RX lines, starting at R0.
