3.3 Setup

The following connections are required for programming (or updating) the software for the wireless camera module:

  • Connections between CC32xx LaunchPad and wireless camera module (see Figure 3-2):
    • UART TX
    • UART RX
    • GND
    • Reset
    • VSENSE (Level shifter voltage)
Note: Unmount the headers as shown in Figure 3-1.

  • Reset Connection: For proper operation of the OA7000, the Wi-Fi device should be able to reset it. To do so, HOST_ON pin (pin 8, J7 connector) of the camera module is connected to the NWP debug pin (pin 2, J13 connector) as shown in Figure 3-3.

  • Optional connections required for debug over JTAG
    • JTAG (JTAG connector from LaunchPad connected to the J5 connector of the camera module as shown in Figure 3-4)
    • nRESET
    • GND
