This kit comes with a cool memory LCD, two capacitive touch buttons, and of course the built-in debugger and AEM system so you only need a USB port in your computer to start developing (and of course Simplicity Studio
How to participate:
We will choose the three (3) best comments/applications, and these participants will receive the very first ZG starter kits available!
This contest ends on October 20th, 2013.
I thought the Gecko Wonder was low power, but the Zero’s power management is even more frugal and better fitted for remote environmental sensing. Coupling sensing with energy harvesting techniques, the Zero Gecko can run by itself. The display can act as a setup screen, level monitor, timer and alarm indicator. Temperature and vibration sensors are missing from the starter board, but easily added through the I2C or low power UART serial interfaces. The Gecko family just keeps getting more useful. :-)
We are actually using both Gecko and Tiny Gecko chips for our development. While we definitely need a Cortex M3 for our main software, the Gecko Wonder might be a better fit than the Tiny Gecko for lower power consumption as our secondary chip.
I want to use this kit to make an unique battery less bicycle computer. I plan to use the energy harvested from a couple of magnets attached to the spokes / wheel rim and a stationary coil attached to the frame. As a bonus the magnets can be used to measure the speed using a hall-effect sensor.
The ultra low power Zero Gecko and the Sharp Memory LCD is the perfect fit for this application !
I am working on a 'Digital Spirit Level'. The design will be equipped with EFM32ZG, low power segmented LCD (memory LCD might do better - need to test), and a sensor. All powered from 2xAA batteries - from calculations so far looks like over 1 year on this pack (depending on usage).
Currently I use STK with EFM32G and would be nicer to have the actual end chip on STK before the prototype boards.
Main point with ZG for me is power consumption - price - efficiency, all in right spot.
I want to prove that the Zero Gecko can run 24/7 from a small solar cell and a 1F super cap, while logging temperature and humidity at the same time.
This will then be the third (and hopefully last) iteration of my KompMon project (see http://www.hendriklipka.de/hardware/kompmon.html and http://forum.energymicro.com/topic/586-dc12-s2-6-environmental-monitoring-system/ for V1 and V2).
I will skip the whole 'storage in flash' part, and use just the internal RAM together with a RRD schema (round-robin-database) for storing logged data for up to a year (or even more). Also, the memory LCD should allow to display all the logged data all the time without sacrifying runtime.
Last but not least I will try to further reduce the BOM by removing the energy harvesting board. The STK and the super cap should be driven by the solar cell directly (so I will need to add a ultra-low-current LDO, e.g. a TPS78228 or MCP1710).
I can't wait to get my hands on this kit to work on breaking low power records. I would like to do a power consumption test against other low power microcontrollers as well as build some ULTRA low power sensors!
Very excited If I don't win, I'll just have to order a kit
We have a battery powered in-the-mouth device. We'd like the make the battery smaller to make the device more comfortable, and so lower power consumption is the only way to make that happen.
After my first project was started with a GG for the main board of a gas flow computer (with a 128x128 memoryLCD) and a TG for the auxiliary modbus temperature and pressure transmitter (14 bits resolution, 0.05% of FS accuracy with only an average current consumption of 1.5mA (including 0.5mA of current excitation for pressure cell) during the 10ms of acquisition and calculation (linearization and correction of temperature effect)), I wish to migrate the transmitters with a ZG for an even more low power system. In addition, I intend to design a pressure monitoring station (dual pressure measurement) with ZG for the main board (and again a memoryLCD) to communicate with the two pressure transmitters and to send the array of recorded values one time by day with GPRS. In a future low power version, this pressure monitoring station should integrate an UNB modem (TD1208 ;-)) to send periodically the pressure values on a SigFox network (a growing M2M solution dedicated to the low throughput network for the IoT) instead of the GPRS in order to have the pressure values in real time.
