5.2 Setup Test Environment

  1. Power connection:
    1. If testing current, Power on from 5 V DC terminal. If only testing functions, USB power input connector is also OK.
  2. Serial port connection:
    1. Plug USB2Uart in PC.
    2. Connect USB2Uart(TTL) pin to TIDA-010224 board J13 as shown in Figure 3-1.
      1. If selecting universal USB to 3.3 V TTL tool, connect J13.3(TX), J13.5(RX) and J13.9(GND).
      2. If selecting CC32xx EVM, connect the pin as shown in the Connections Between CC32xx LaunchPad™ and Wireless Camera Module (J13 Connector) figure in the Design Guide: TIDA-010224 Low-Power Wireless Camera Reference Design for Extended Battery Life.
  3. Setup serial assist tool:
