3.2 I/O Open and Shorts Test

The CC35xxE device has up to 38 I/O pins, where most pins can be used as GPIOs to support a wide variety of external peripherals. Solder issues from assembly or errors related to the PCB can cause certain connections to or from the CC35xxE device to be open or short circuits. TI gives the option to verify the status of the I/Os and proper connectivity in the PLT using the Radio tool of the SimpleLink™ Wi-Fi Toolbox. The I/O control provides the following options for all GPIOs:

  • Configure to an input or output
  • Set the state of the pin to logic high or logic low
  • Read the logic level on the pin (high or low)
Note: The flash connectivity test is only possible through the SimpleLink™ Wi-Fi Toolbox before the device is activated. Customers must take this into account when defining the PLT and determining the order to complete each step on the production line.
