With this board, GPIO configuration input with PWM and asynchronous communication
using USART is not available.
DfuSe demonstration
The DfuSe demonstration represents additional functionality in the demonstration kit.
Demo application:
●

Then user can program a new workspace using the DfuSe GUI with a USB-to-PC interface.

–
The DfuSe GUI allows application firmware upgrade on the board during run-time.
Users can develop their own application firmware, or make modifications to existing
firmware.
Due to the embedded DFU functionality in the board firmware, JTAG programming is
not required for firmware upgrade.
The DFU layer is the startup layer for the firmware execution. In the DFU layer, a jump
to the application layer is executed.
DFU also supports upload of application firmware to the PC.
So depending on the slave device, the user can select the register address length
(from 0 to 4 bytes; 0 byte length is used for random read and write operations).
After every read or write operation, the GUI updates the status in the status
portion (e.g. status: communication complete / bus free) so that one can check the
status of the SPI communication occurring between the demonstration board and
the SPI slave daughter board. Thus this interface allows one to connect any SPI
interface-based slave device.
