7. Build the project by clicking Build > Build {Project Name} or [Shift] + [F6]. After the project is
built without errors and warnings, program (by clicking Debug > Program) the project to PSoC 4
through the PSoC 5LP USB programmer or MiniProg3.
Connect the RX line of the PSoC 4 to J8_10 and TX line of the PSoC 4 to J8_9, as shown in the
following figures.

Note: UART RX and UART TX can be routed to any digital pin on PSoC 4 based on the configura-
tion of the UART component. An SCB implementation of UART will route the RX and TX pins to
either one of the following subsets: (P0[4], P0[5]) or (P3[0],P3[1]) or (P4[0],P4[1]).
