Content

+

The abstraction is made of the following files:

+
+
  • evk1100.h:a preprocessor mapping of the on-board AT32UC3A pins connections to the on-board hardware resources.
    • +
    +
    +
  • led.c and led.h: a specific set of functions to easily control the EVK1100 LEDs.

    This driver provides an API to get access to the main features of the GPIO controller.

    +

     

    +

    The driver is composed of gpio.c and gpio.h (for accurate API description, read this header file).

    +

     

    + +

    GPIO Software Driver Examples

    +

    Two examples are currently available: +

  • demonstrates the peripheral bus interface;
    • +
  • demonstrates the local bus interface.

    AVR UC3 Series Software Framework: Power Manager Driver
    +

    + +

    Copyright © 2007 Atmel Corporation

    + +

    Introduction

    +

    UC3A0/1, UC3B, UC3A3

    +

    The Power Manager (PM) controls the oscillators and PLLs, and generates the clocks and +resets in the device. The PM controls two fast crystal oscillators, as well as two PLLs, which can +multiply the clock from either oscillator to provide higher frequencies. Additionally, a low-power +32 KHz oscillator is used to generate the real-time counter clock for high accuracy real-time +measurements. The PM also contains a low-power RC oscillator with fast start-up time, which +can be used to clock the digital logic.

    + +

    UC3L, UC3C

    +

    The Power Manager (PM) provides synchronous clocks used to clock the main digital logic in the +device, namely the CPU, and the modules and peripherals connected to the HSB and PBx buses. The PM also +contains advanced power-saving features and a Reset Controller.

    + + +

     

    + +

    Power Manager Driver

    +

    UC3A0/1, UC3B, UC3A3

    +

    The driver is composed of pm.c and pm.h.

    +

     

    +

    This driver provides interfaces for PM main hardware features: + +

  • oscillator source setup: external or crystal; +
  • oscillator startup; +
  • PLL setup; +
  • main clock source setup. +

    +

     

    +

    Two examples are available:

    + EXAMPLE1: how to configure the Power Manager to use Oscillator 0 as source of main clock, generic clock configuration and switch to a sleep mode

    + EXAMPLE2: how to configure a PLL and switch the main clock to PLL output and do a generic clock configuration.

    +

     

    + +

    + The file pm_conf_clocks.c provides functions to simplify the usage of this driver. + It is used to configure all clocks at once by specifying frequencies needed. +

    + +

    + The file power_clocks_lib.c (and power_clocks_lib.h) + provides functions to abstract features such as oscillators/pll/dfll configuration, clock configuration, System-sensible + parameters configuration, buses clocks configuration, sleep mode, reset. +

    +

    + +

    UC3L

    +

    The driver is composed of pm_uc3l.c and pm_uc3l.h.

    +

     

    +

    This driver provides interfaces for PM main hardware features: +

  • main clock source setup, +
  • clock domains setup, +
  • peripheral modules setup, +
  • Sleep modes setup, +
  • reset, +
  • PM interrupts setup. +

    +

     

    +

    Three examples are available:

    + EXAMPLE1: how to configure the Power Manager to use Oscillator 0 as source of main clock, generic clock configuration and switch to a sleep mode. This example is not applicable to the AT32UC3L-EK board because no external crystal/clock is connected to OSC0 on that board.

    + EXAMPLE2: how to configure a DFLL and switch the main clock to the DFLL output and do a generic clock configuration.

    + EXAMPLE2: how to use the RC120M internal oscillator as main clock source and do a Generic clock configuration.

    +

     

    + +

    UC3C

    +

    The driver is composed of pm_uc3c.c and pm_uc3c.h.

    +

     

    +

    This driver provides interfaces for PM main hardware features: +

  • main clock source setup, +
  • clock domains setup, +
  • peripheral modules setup, +
  • Sleep modes setup, +
  • reset, +
  • PM interrupts setup. +

    +

     

    +

    Two examples are available:

    + EXAMPLE1: how to configure the Power Manager to use Oscillator 0 as source of main clock, generic clock configuration and switch to a sleep mode

    + EXAMPLE2: how to configure a PLL and switch the main clock to PLL output and do a generic clock configuration.

    +

     

    + +

    + The file power_clocks_lib.c (and power_clocks_lib.h) + provides functions to abstract features such as oscillators/pll/dfll configuration, clock configuration, System-sensible + parameters configuration, buses clocks configuration, sleep mode, reset. +

    AVR UC3 Series Software Framework: USART Driver
    +

    + +

    Copyright © 2007 Atmel Corporation

    + +

    Introduction

    +

    This driver will let you communicate through serial ports of all AVR®32 AT32UC3 devices.

    +

     

    + +The USART driver philosophy of usage is: +
  • Configure one (or several) USART in the wanted mode [usart_init_xxxxx]
    • +
  • Send or receive data on the configured USART, [usart_putchar, usart_getchar, usart_write_line, ...]
    • + +

    USART Driver

    +

    The driver is composed of usart.c and usart.h.

    +

    + +

     

    +

    One example is currently available:

    +

  • Simple access to a serial port

    • +

The + * standard demo tasks don't provide any useful functionality other than to + * demonstrate the FreeRTOS API being used and show how the scheduler behaves. + * + * A COM test is included whereby one task transmits characters on the UART + * which are then received by another task. A loopback connector is required + * on the UART1 connector for this test to pass (pins 2 and 3 need to be + * connected together - a paper clip is usually all that is required). LED + * 5 red and green are under the control of the COM test tasks. Red will toggle + * each time a character is successfully transmitted, and the green LED toggles + * for each received character. + * + * In addition this file creates a 'Check' task. This periodically inspects + * the standard demo tasks and makes a few other simple tests to see if the + * system is performing as expected. The check task toggles LED 6 green every + * 3 seconds provided no errors exist and sets it to red if an error has + * occurred. The toggle rate will increase to 500ms if an error is detected + * at any time. This mechanism can be tested by removing the loopback + * connector from UART1, and in so doing deliberately generating an error in + * the COM test task. + * + * LED 1 through 4 are controlled by simple LED flashing tasks. Each should + * toggle at a fixed but different frequency. + * + */ + +#include +#include +#include + +/* Environment header files. */ +#include "pm.h" + +/* Scheduler header files. */ +#include "FreeRTOS.h" +#include "task.h" + +/* Demo file headers. */ +#include "partest.h" +#include "serial.h" +#include "integer.h" +#include "comtest.h" +#include "PollQ.h" +#include "semtest.h" +#include "dynamic.h" +#include "BlockQ.h" +#include "death.h" +#include "flop.h" +#include "flash.h" + +/* Task priorities. */ +#define mainLED_TASK_PRIORITY ( tskIDLE_PRIORITY + 1 ) +#define mainCOM_TEST_PRIORITY ( tskIDLE_PRIORITY + 2 ) +#define mainQUEUE_POLL_PRIORITY ( tskIDLE_PRIORITY + 2 ) +#define mainSEM_TEST_PRIORITY ( tskIDLE_PRIORITY + 1 ) +#define mainBLOCK_Q_PRIORITY ( tskIDLE_PRIORITY + 3 ) +#define mainCHECK_TASK_PRIORITY ( tskIDLE_PRIORITY + 4 ) +#define mainCREATOR_TASK_PRIORITY ( tskIDLE_PRIORITY + 3 ) +#define mainFLASH_TASK_PRIORITY ( tskIDLE_PRIORITY + 1 ) + +/* Baud rate used by the loopback test task. */ +#define mainCOM_TEST_BAUD_RATE ( ( unsigned long ) 38400 ) + +/* LED used by the serial port tasks.
