Mechanical buttons
SAM4S Xplained Pro contains two mechanical buttons. One button is the RESET button connected to the
SAM4S reset line and the other is a generic user configurable button. When a button is pressed it will drive the
I/O line to GND.

LED
There is one yellow LED available on the SAM4S Xplained Pro board that can be turned on and off. The LED
can be activated by driving the connected I/O line to GND.
Table 4.12. LED connections
Analog reference
An adjustable voltage reference is implemented on the kit to have a reference for the ADC or DAC. The
reference can be adjusted with the on-board multiturn trimmer potentiometer. Next to the potentiometer, a 2-pin
header is available to measure the reference voltage for the AREF pin of the SAM4S. The voltage output range
for the reference is 0V - 3.36V.
Embedded Debugger implementation
SAM4S Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and debug the
ATSAM4SD32C using Serial Wire Debug (SWD). The Embedded Debugger also include a Virtual Com port
interface over UART, an Atmel Data Gateway Interface over SPI and TWI and it monitors four of the SAM4S
GPIOs. Atmel Studio can be used as a front end for the Embedded Debugger.
Serial Wire Debug
The Serial Wire Debug (SWD) use two pins to communicate with the target. For further information on how to
use the programming and debugging capabilities of the EDBG, see
Table 4.13. SWD connections
Virtual COM port
The Embedded Debugger act as a Virtual Com Port gateway by using one of the ATSAM4SD32C UARTs. For
further information on how to use the Virtual COM port see
Table 4.14. Virtual COM port connections
