TI CC3220SF LAUNCHXL

The CC3220SF LAUNCHXL board contains a TI CC3220SF device.

Jumper Settings

  • Set RX and TX to provide UART communications via the onboard USB debugger.

ADC Examples Pin Connections

Important: The inputs to the ADC are required to be well within 1.4 VDC to avoid clipping, which will cause distortion. The ADC inputs can be damaged if an input voltage higher than 1.8 VDC is applied to these pin. The 1.8 VDC 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 CC3220SF LAUNCHXL has a protective circuit to allow an input of 3.3 VDC. 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.

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

Reset Behavior

By default, the application is not retained after a power reset. To enable retention of the application for debug purposes, the application should add the following pre-defined symbol: __SF_DEBUG__. This will place a header, Board_debugHeader, into flash. This header is defined in the Board.c file.

Note: The user should ensure the Board_debugHeader is erased if retention of the application is no longer desired. The Board.c file will erase the Board_debugHeader if __SF_NODEBUG__ is defined.

Floating point

The current build is set to add support for single-precision floating point. Meaning that System.Math API supports only the float overloads. The double ones will throw a NotImplementedException.

nanoBooter

Because this CPU uses a proprietary boot mechanism that copies the application from the SPI flash memory to the Cortex-M application core, it does not use nanoBooter.

Flashing nanoCLR
