Board Resources Used in Driver Examples

The following table lists the Board names of the resources used by the driver examples, and their corresponding pins. Note that there may be other resources configured in the board files that are not used by any driver example. Only the example resources are listed in the table.

BoosterPacks

The following examples require BoosterPacks.

Example BoosterPack
fatsd SD Card BoosterPack
fatsdraw SD Card BoosterPack
i2secho Audio BoosterPack
portable BOOSTXL-SENSORS Sensors BoosterPack (optional)
sdraw SD Card BoosterPack

For the fatsd, fatsdraw and sdraw examples, modifications must be made to the SD Card BoosterPack. See the section below for details.

SD Card BoosterPack Modifications

Scratch out the following traces:

Solder shorts for the following:

ADC Examples Pin Connections

Important: The inputs to the ADC are required to be well within 1.4V to avoid clipping, which will cause distortion. The ADC inputs can be damaged if an input voltage higher than 1.8V is applied to these pin. The 1.8V hard limit must be considered from both the SW and HW points of view. Always add a resistor divider/buffer to bring down the measurement signal voltage to within the ADC limits. See the CC32xx ADC Appnote for more details.

The CC3220S LAUNCHXL has a protective circuit to allow an input of 3.3VDC. The 5V should NOT be used for this may damage the ADC inputs. For testing, the following jumpers must be present: J5 = OPAMP EN, J10 = GND, J13 = BRD. In some instances, an additional header may need to be soldered for J5.

Note: There are duplicate pins P59 and P60 on the board. Choose the ones connected to the Booster Pack headers (the pins not connected to the Booster Pack headers have an asterisk next to them).

Peripherals Used

The following list shows which CC3220S peripherals are used by driver and kernel applications. Driver examples control which peripherals (and which ports) are used.
