SAM4C32-EK Firmware Demonstration

SAM4C32-EK Default Application

The SAM4C32-EK is delivered with a preprogrammed default application in SAM4C32 Flash memory. This
application implements SAM4C32 embedded peripherals and external (on-board) peripherals as detailed in the
table below.

After the first power-up without the backup battery, the time (hour and minute) of the RTC can be configured. The
Hour and Minute settings are entered using the following push buttons:

BP4 (SCROLL_UP)—sets the Hour (24H mode entries must be made)

BP5 (SCROLL_DOWN)—sets the Minute

BP6 (TMP2)—saves the Hour and Minute settings

Once the time settings have been saved, BP4 (SCROLL_UP) can be used to toggle the Hour display between 12H
or 24H mode.

Note:

RTC time configuration can be skipped by pressing BP6.

Once the hour and minute have been configured, the main application on core 0 runs in an infinite loop, repeating
the following steps:

Every second, the time is displayed with colon (:) icon blinking

Every fifteen (15) seconds, the VDDBU pin voltage is measured and displayed 

(1)

Every thirty (30) seconds, the temperature (using the AT30TS75) is measured and displayed in °C and in °F.

Note:

1.

On the SAM4C32-EK, the voltage measured is the VDDIO voltage minus the forward voltage of the diode in the 
BAT54C (D4).

At startup, the main application configures the core 1 subsystem to run a CoreMark algorithm from the core 1
SRAM memories (SRAM1 and SRAM2). Once the CoreMark is finished, the result of the CoreMark (number of
CoreMark/MHz) is passed to the main application using the inter-processor communication embedded in the
SAM4C32. Once the result is retrieved by the main application, the result of the CoreMark is displayed and the
CoreMark algorithm running on core 1 is restarted. An ammeter connected either on JP12 (VDDIN) or on JP6
(VDDCORE) can measure the active current consumption of both cores.
