Introduction

While some devices require exact timing, and therefore require an external calibration crystal or other high-accuracy clock source, other applications with looser accuracy requirements may use the internal RC Oscillator(s) for space and/or cost reasons. However, this can lead to unstable communication interfaces if the internal oscillator is not first calibrated against an accurate reference clock.

This application uses a known external reference frequency to calibrate the internal 8MHz (nominal) RC Oscillator, OSC8M, so that it is as close as possible to the desired 8MHz frequency.

This application has been tested on following boards:

• SAM D20/D21 Xplained Pro

Usage Instructions

On startup, the application will immediately begin calibration of the OSC8M internal oscillator, against a 32.768KHz watch crystal attached to the device XOSC32K pins (see device datasheet). As the possible calibration values are cycled through, the board LED will turn on each time a better match is found, and turn off when an equal or lesser calibration value is tested. Once the best values are found, the results are printed to the device USART and the board LED will flash rapidly to signal the end of the calibration sequence.

Note

The calibration values are not stored to the device's non-volatile memory. The example execution time is depend on the configuration in conf_example file. It's about (2<<CONF_CALIBRATION_RESOLUTION) *(2<<CONF_FRANGE_CAL -1)*(2<<CONF_TEMP_CAL -1)*128/32768 seconds. To get more accurate result, we can increase the value of CONF_FRANGE_CAL, CONF_TEMP_CAL and CONF_CALIBRATION_RESOLUTION, but the execution time is also longer.

Introduction

This application demonstrates a runtime XOSC32K (external 32KHz crystal oscillator) failure detector, using hardware timer peripherals and the SAM event system.

A pair of timers are linked together; one with a clock source from the XOSC32K 32.768KHz external clock, and another from the OSC32K 32.768KHz internal RC clock source. Each time the XOSC32K timer reaches a configurable count value, a hardware event resets the second timer using the OSC32K clock source.

If the OSC32K clocked timer reaches a configurable count value before it is reset by the XOSC32K timer, the XOSC32K clock source is considered failed and a callback function is executed. If instead the XOSC32K closed clocked timer resets the OSC32K clocked timer, the oscillator is considered OK and another callback function is executed.

In the example application, the DFLL reference clock is automatically switched between the internal and external 32KHz clock sources depending on the external reference availability.

This application has been tested on following boards:

• SAM D20/D21/R21/L21/D11/R30 Xplained Pro

Usage

Connect an oscilloscope to PA28 of the SAM D20/D21 or PB22 of SAMR21 or PA08 of SAM D10/D11 or PA27 of SAML21 or PA14 of SAMR30 Xplained Pro. Run the example application, and press and hold the board button to turn off the external XOSC32K crystal clock source to observe the fail-over to the internal clock source. Releasing the button will re-enable the external crystal.

The board LED will be turned on when the external crystal is used, and will be turned off when the internal RC is used due to a crystal failure detection.

• Resets the device after programming and starts executing application

Introduction

As many electronic designs evolve rapidly there is a growing need for being able to update products, which have already been shipped or sold. Microcontrollers that support boot loader facilitates updating the application flash section without the need of an external programmer, are of great use in situations where the application has to be updated on the field. The boot loader may use various interfaces like SPI, UART, TWI, Ethernet etc.

This application implements a I2C Slave bootloader for SAM devices.

This application has been tested on following boards:

• SAM D20/D21/R21/D11/L22/L21 Xplained Pro

Program Memory Organization

This bootloader implementation consumes around 8000 bytes (approximately), which is 32 rows of Program Memory space starting from 0x00000000. BOOTPROT fuses on the device can be set to protect first 32 rows of the program memory which are allocated for the BOOT section. So, the end user application should be generated with starting address as 0x00002000.

Prerequisites

There are no prerequisites for this implementation

Hardware Setup

SAM device in SAM Xplained Pro kit is used as the I2C Slave. I2C master should be connected to PIN11 (PA08 - SDA) and PIN12 (PA09 - SCL) on External header 1 (EXT1) of SAM D20/D21 Xplained Pro. I2C master should be connected to PIN11 (PA16 - SDA) and PIN12 (PA17 - SCL) on External header 1 (EXT1) of SAM R21 Xplained Pro. I2C master should be connected to PIN11 (PA22 - SDA) and PIN12 (PA23 - SCL) on External header 1 (EXT1) of SAM D10/D11 Xplained Pro. I2C master should be connected to PIN11 (PB30 - SDA) and PIN12 (PB31 - SCL) on External header 1 (EXT1) of SAM L22 Xplained Pro. I2C master should be connected to PIN11 (PA08 - SDA) and PIN12 (PA09 - SCL) on External header 1 (EXT1) of SAM L21 Xplained Pro. SW0 will be configured as BOOT_LOAD_PIN and LED0 will be used to display the bootloader status. LED0 will be ON when the device is in bootloader mode.

Bootloader Process

Boot Check

The bootloader is located at the start of the program memory and is executed at each reset/power-on sequence. Initially check the status of a user configurable BOOT_LOAD_PIN.

• If the pin is pulled low continue execution in bootloader mode.
• Else read the first location of application section (0x00002000) which contains the stack pointer address and check whether it is 0xFFFFFFFF.
  • If yes, application section is empty and wait indefinitely there.
  • If not, jump to the application section and start execution from there.

    Note

    Configuring the BOOT_LOAD_PIN and disabling watchdog in this boot mode check routine are made with direct peripheral register access to enable quick decision on application or bootloader mode.

Initialization

Initialize the following

• Board
• System clock
• I2C Slave module
• NVM module

Boot Protocol

• I2C Master first sends 4 bytes of data which contains the length of the data to be programmed
• Read a block from I2C Master of size NVMCTRL_PAGE_SIZE
• Program the data to Program memory starting APP_START_ADDRESS
• Send an acknowledgement byte 's' to I2C Master to indicate it has received the data and finished programming
• Repeat till entire length of data has been programmed to the device

Start Application

Once the programming is completed, enable Watchdog Timer with a timeout period of 256 clock cycles and wait in a loop for Watchdog to reset the device.

Introduction

This application demonstrates how to configure the ADC in a sleepwalking operation, where the input voltage is measured at a fixed interval, but the device is not woken from sleep until the measured value is below a given threshold; in this application 0.5 Volts.

This application has been tested on following boards:

• SAM D20/D21/R21/D11/L21/L22/C21/R30 Xplained Pro

Hardware Setup

This application use AIN0 as ADC input channel. When the measured voltage is lower than 0.5V, then the device will start toggling the led pin to signal that the low voltage condition has happened. Connect the PA02(EXT3 pin3) to GND in SAM D20/D21 Xplained Pro to trigger it. Connect the PA06(EXT1 pin3) to GND in SAM R21 Xplained Pro to trigger it. Connect the PA02(EXT1 pin3) to GND in SAM D10/D11 Xplained Pro to trigger it. Connect the PA03(EXT1 pin4) to GND in SAM L21/L22 Xplained Pro to trigger it. Connect the PA03_ADC_DAC_VREF(J701 pin4) to GND in SAM C21 Xplained Pro to trigger it. Connect the PA04(EXT1 pin14) to GND in SAM R30 Xplained Pro to trigger it.

If debugging it is also possible to start a debug session and place a breakpoint in the window callback that will trigger whenever the voltage has gone below the defined threshold.

The application can easily be modified to monitor other voltages by changing the input source and threshold values in the adc_setup function.

Implementation Details

ADC Configuration

The ADC is configured to perform hardware averaging on the measured value, where the ADC will sample the signal 16 times and find the average value in hardware. This smooths out high frequency noise.

Sample timing

To trigger the ADC conversions, the RTC is setup in 32-bit counter mode, clocked by the internal 32kHz oscillator divided by 32, giving a 1kHz input clock. A compare value of 1000 is used to trigger the ADC conversion every second.

Event Routing

The Event system is setup to route the compare match interrupt from the RTC to the ADC, and the ADC is configured to start a new conversion on an event input. The event channel is configured as an asynchronous channel, so no clock is needed for the event channel during sleep.

• SAM D21 Xplained Pro

Hardware Setup

A sine wave signal should be applied on pin PA04 in the SAM D21 Xplained pro board. More details on analog input signal specification can be found in application note 'Analog Comparator Application Examples'. The device's analog comparator output pin (PA12) should be connected to an oscilloscope so that the generated waveform can be monitored.

Usage

The waveform selection macro AC_MODE should be set to required AC example.

The application will first configure the system clock and then configures the analog comparator based on selected example mode. In level crossing application, the output pin PA12 will be set when the analog input is above a threshold level. In window mode application, the output pin will be set whenever the input signal goes out of a window with two threshold levels. In false spike avoider application, hysteresis and filter mode are enabled which avoid frequent toggling of AC output when the analog input oscillates around the detect threshold. In SleepWalking mode, the analog comparator is configured in single shot mode which performs comparison every 10ms which is timed from RTC and triggered through Event System that reduces the overall current consumption of the system.
