CC2650STK: IO driver initialization for minimal energy consumption - BoardGpioInitTable (Z-Stack_Home_1.2.2a)

filippo n

Part Number: CC2650STK

Hi to everyone,

From main:

PIN_init(BoardGpioInitTable); // C:\ti\tirtos_simplelink_2_11_01_09\packages\ti\boards\SensorTag\CC26XXST_0120

is called to setup safe settings for this board.

Suppose use a default firmware version (zstack_home_1_02_02a_44539), I want to know the pin configuration of board to spend a minimum energy consumption.

Thanks to everyone!

Hi filippo,

By default, the I/O driver (output) and input buffer (input) are disabled (tri-state mode) at power on or reset, and thus the I/O pin can safely be left unconnected (floating).

Hi to everyone,

I also documented thanks to your suggestions.

I correctly configured the pins in BoardGpioInitTable and I actually monitored the consumption with the oscilloscope...and ok now it's correct! sleep-mode consumption is around 50 uA.

Thanks!
