BoosterPacks

The following examples require BoosterPacks.

Example BoosterPack
fatsd microSD Card BoosterPack or SD Card BoosterPack
fatsdraw microSD Card BoosterPack or SD Card BoosterPack
i2secho Audio BoosterPack
sdfatfs SD Card BoosterPack
sdfatfsraw SD Card BoosterPack
portable BOOSTXL-SENSORS Sensors BoosterPack (optional)

For the sdfatfs and sdfatfsraw examples, modifications must be made to the SD Card BoosterPack. See the section below for details.

ADC Examples Pin Connections

The ADC examples sample input from the A0 and A1 pins. These pins should be connected to the analog input. For quick testing on the CC3220SF LAUNCHXL, the A0 pin can be connected to 3V3 and A1 to GND. The CC3220SF 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.

ADC Pin (Function) Analog Input
P59 (A0) –> 3V3
P60 (A1) –> GND

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).

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.

Peripherals Used

The following list shows which CC3220SF peripherals are used by driver and kernel applications. Driver examples control which peripherals (and which ports) are used.
