As Figure 2-12 shows, C
TANK
is connected to pin J2.3. This Arduino header pin connects C
TANK
to P0.2 of CY8CKIT-040 .
Within PSoC Creator, you should configure this pin as the
“shield tank capacitor” in the
Advanced tab of the CapSense
Component Configuration window when you develop projects with the CY8CKIT-040 kit.
Also note that jumper J14 on CY8CKIT-040 should be removed (as Figure 2-13 shows) before connecting CY8CKIT-024 to
CY8CKIT-040 . This is because J14 connects pin P0[2], that is, the C
TANK
pin on CY8CKIT-024 , to an RGB LED on
CY8CKIT-040 , which must not be connected when C
TANK
is used.
Figure 2-13: Remove J14 from CY8CKIT-040
Note that for CY8CKIT-042 , the onboard shield tank capacitor should be used instead of C
TANK
on CY8CKIT-024 .
Refer to the CapSense CSD Component datasheet or PSoC 4 CapSense Design Guide for more details on the use of the
shield tank capacitor.
2.3.6 LEDs
The CY8CKIT-024 kit has six onboard LEDs, five of which (LED1
–LED5) are arranged in a “+” layout.
Figure 2-14 shows
the arrangement of LEDs on the CY8CKIT-024 kit.

All the LEDs are connected in an active-LOW configuration; the anodes of all the LEDs are connected to P4_VDD, which is
the power pin on the J1 Arduino header.
Figure 2-15 shows the connection diagram.
