The second example project (test3_cap) demonstrates a
CapSense-driven keypad. It indicates and collects data
from the CSR User Module measurements. This data
helps monitor keypad performance and optimize the CSR
User Module properties and PCB layout. The Slave_Addr
parameter for this example is set to 5. Figure 4 shows the
operation of this project – the period value during
sequential pressing of keypad buttons.
