4_Inkplate_Touchpads example for e-radionica.com Inkplate 6
|
||
|
|
For this example you will need only a micro USB cable and Inkplate 6.
|
||
|
|
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
|
||
|
|
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:

||

|
||
|
|
|
||
|
|
This example will show you how you can use built-in touchpads (on PCB marked with numbers 1, 2 and 3).
|
||
|
|
These are basically touch sensitive switches. You can read state each of these with function readTouchpad()
|
||
|
|
and the argument you need to pass to this function is PAD1 if you want to read the state of touchpad marked
|
||
|
|
as "1" on PCB, PAD2 for second touchpad, PAD3 for third. You can also use numbers as arguments.
|
||
|
|
For that you need to pass number 0 for touchpad that is marked as 1 on PCB, 1 for second touchpad and 2 for third.
|
||
|
|
Function will return 1 if selected touchpad is pressed, zero if not.
|
||
|
|
|
||
|
|
In this example, if you touch first pad, ti will decrese number showed on screen, if you touch thirs touch pad,
|
||
|
|
it will increase the number, if you touch second touchpad, it will reset number to zero.
|
||
|
|
|
||
|
|
NOTE: You can not use touch pads when enclosure is fitted on the Inkplate - they are not that sensitive!
