3.3.4 LPSTK-CC1352R Configuration Steps for Camera Module

Use the following steps to configure the LPSTK-CC1352R.

  1. Ensure the SDK for CC13x2 (v4.30) and CC1310 (v4.10) has been installed.
  2. Import and build the following project using CCS: ‘OV_camera_design_CC1352R1_LAUNCHXL_tirtos_ccs’ available in the software files at TIDA-010224.
  3. Flash the .out file generated in the ‘Debug’ folder using Uniflash.
  4. To program the LPSTK-CC1352R LaunchPad, use the debugger section of any LaunchPad (for example, CC32xx LaunchPad): connect the RX, TX, GND terminals of the debugger LaunchPad to the LPSTK-CC1352R LaunchPad. (Additionally, connect VSENSE to MCU supply for CC32xx LaunchPad.)
  5. Optional: Place the JTAG port connection between the debugger CC32xx LaunchPad and LPSTK CC1352R LaunchPad for debug.

Once the previous steps are complete and LPSTK-CC1352R LaunchPad is mounted on the camera module:

  • The camera module is in standby state on power-up. The camera module can be triggered into active mode (for video streaming) for 30 seconds by either pressing the button (SW2) or using external PIR trigger, or radio. After 30 seconds, the camera module will revert back to the standby state. Refer to turn on or turn off logic available in event handler.c for more details.
  • The software also updates the battery voltage every 5 minutes. The battery voltage can be monitored by connecting the UART port using a terminal.
    • Command sequence required to be sent is: 0x55 0x01 x0FE 0x04
    • The device will then echo back 0x55 0x02 0xFD 0x05 0xLL 0xHH, where LL and HH is the ADC reading. HHLL provides the voltage in mV.
    • For example, 0x55 0x02 0xFD 0x05 0xFE 0x10 corresponds to measured 4.342-V battery voltage.
