Low-power Application Kit (Oryx)

The Low-power Application Kit (Oryx) with NXP's LPC11U37 ARM Cortex-M0 microcontroller has been designed to make it as easy as possible to get started with Cortex-M0 and low-power designs.

The board demonstrates low-power design techniques both in hardware and software. Includes an extensive user's manual and many sample applications.

The LPC11U37 has 10 kB SRAM, 128 kB Flash, 4 kB E2PROM, USB 2.0 Full-Speed Device, SSP, I2C, UART, ADC, etc.

On-board embedded debug interface, powered by LPCXpresso technology. LPCXpresso is a low-cost development toolchain available from NXP. The toolchain supports ARM-based LPC microcontrollers and includes a free Eclipse-based IDE and low-cost target boards combined with a JTAG debugger. Designed for simplicity and ease of use, the LPCXpresso technology provides software engineers a quick and easy way to develop their applications from initial evaluation to final production.

This board is an enhancement of the Oryx Board - Ultra Low-Power Reference Design for Mobile Applications from Arrow. Developed in close cooperation with NXP and Arrow.

Oryx?

The Oryx is one of four large antelope species. It prefer near-desert conditions and can survive without water for long periods - very low-power operation... just like this kit!

Even in full operating mode, the Low-power Application Kit (Oryx) consumes only 42mW (3.0V, 14mA) and as low as 20uW (3.0V, 6.6uA) in power-down mode.

There are multiple possibilities to control the power consumption of the board.

Software

Sample Software Disclaimer

The sample applications contain project files for the free LPCXpresso IDE/Debugger.

Accel_systick_irq-wakeup – this application demonstrates the accelerometer features including tap detection (single and double). The application used sleep mode and wakes up from sleep by an interrupt from the accelerometer or systick counter (for refreshing the LCD).
DeepPowerDown – this application demonstrates the program structure needed when working with deep power down. The application counts the number of times the wakeup push-button is pressed.
DemoApp – this is the pre-loaded application that the boards are delivered with.
FlashApp – this application demonstrates how to program bmp pictures to the serial flash.
LCD_ADC_temp_wdt-wakeup – this application demonstrates how the WDT can be used to wake up from power down mode. The WDT is the only peripheral active during power down mode and it can be used to achieve a regular interrupt for refreshing the LCD. This sample application can be used to demonstrate the (about) 2.5uA total power consumption in power down mode.
LCD_graphics – this application demonstrates the graphical library and the possibilities with the graphical LCD.
lib_LPC11U14Dev – this is a library that has been created for the on-chip peripheral. The content is mostly from standard driver’s library that NXP provides, but some things have been changed to fit the low-power application board. The library is compatible with LPC11U37.

lib_OryxDev – this is a library that has been created for the low-power application board (Oryx) peripherals, like accelerometer, RTC, serial flash, LCD, etc.
ProductionTest – this is not a sample application but the actual application that is used in production of the board. This application tests connection with the on-board peripherals and also programs some BMP pictures on the serial flash. This application can be used to verify that a specific board is correct (if a hardware error is suspected).
RTC_irq-wakeup – this application demonstrates the RTC and how the 1Hz tick can be used.
Semihosting_ADC_temperature_sleep – this application demonstrates semihosting, which is a technique where an application can use printf() to display information on the LPCXpresso IDE.
Systick_wdt_lcd_capsense – this application demonstrates the capacitive sensors.
USB_HID – this application demonstrates USB HID. Use in conjunction with the NXP application for LPC1xxx HID. It is possible to control the LED on the low-power application board and the Wakeup push-button can signal back to the PC (LPC1xxx HID application on the PC).
