Working With the TPB2L Keypad

A diagram illustrating the layout of the Size 2 Tibbo Project Box With LCD/Keys (TPB2L).

Installing a TPP2 or TPP2(G2) and its attached Tibbits inside a TPB2L creates a Size 2 Tibbo Project System With LCD/Keys (TPS2L). This device features a four-key sensor keypad.

Use the code below to set up the kp. object for working with the keypad of the TPS2L and reset the keypad:

Tibbo BASIC:

							'Reset the touch controller of the keypad
io.num=PL_IO_NUM_44
io.enabled=YES
io.state=LOW
io.state=HIGH

'Set up the kp. object
kp.returnlinesmapping="36,37,38,39"			'no return lines
kp.enabled=YES
						

The key_code argument of the on_kp event will return the following keycodes:

Code 0 for the left-most key
Code 1 for the second key (counting from the left)
Code 2 for the third key (counting from the left)
Code 3 for the right-most key
