Wag the OpenLog
The OpenLog Artemis has graduated from SparkX and we have a new version of our popular Qwiic Kit for Raspberry Pi!
Hello, everyone! This week we have another handful of new products, beginning with the SparkFun OpenLog Artemis. This new data logger has just graduated from SparkX, and provides you with an Artemis-powered, plug and play logger with a built in, high resolution 9DoF IMU! We have also revised our popular Qwiic Kit for Raspberry Pi to include the Qwiic pHAT v2.0. Last up this week, we have a new 5V, 2A wall charger.
Don't forget that you can get a free SparkFun Qwiic Pro Micro BoogieBoard with any purchase of $75 or more using promo code "BOOGIEBOARD20" (some restrictions apply). Supplies are running short so get yours before we run out!
Now onto our new products!
Read us like an open log!
The SparkFun OpenLog Artemis is an open source data logger that comes preprogrammed to automatically log IMU, GPS, serial data and various pressure, humidity and distance sensors - all without writing a single line of code! OpenLog Artemis, or "OLA," automatically detects, configures and logs Qwiic sensors. The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project.
Ready to get started with Raspberry Pi and Qwiic? The SparkFun Qwiic Starter Kit for Raspberry Pi includes the SparkFun Qwiic pHAT v2.0 for Raspberry Pi, which adds four Qwiic connectors to your Pi. It also includes a VCNL4040 Proximity Sensor Breakout, Micro OLED Breakout, Environmental Combo Breakout and plenty of Qwiic Cables to connect everything together!
USB as a power connection standard is common these days, but you don't always have a computer on hand, so how are you going to power all of your sweet USB devices? How about a high quality switching 'wall wart'? This AC to DC power supply will do 5V at 2A! They're switch mode power supplies which means the output is regulated to 5V.
That's it for this week! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!
On the SparkFun OpenLog Artemis, since it's an Artemis it has BLE hardware, the "obvious" thing would be to communicate via BLE.
Looking through the documentation, I would wish that a couple of the GPIO pins be brought out to headers, though that might make the board need to be a little bigger. (I suppose I could use A11 as a digital input, but would prefer to keep it for analog.) I can think of some uses where I'd like to "log on event" rather than "log on time" -- and need to wake it with an "interrupt on change". (Seems kinda silly to do a 10Hz "polling" for events that happen just a few times a day...)
As of v1.6 firmware, data logging can be externally triggered with an interrupt's falling/rising edge rather than at regular timed intervals. =)
Hmm, as far as the polling for events and interrupt on change, you may want to file a feature request on the OLA GitHub repo to see if that is possible. I remember our old Wake on Shake did something similar to power a load with the ATtiny2313A whenever the ADXL362 detected movement. I'm not sure how feasible it is as this with the OLA as this would probably require a threshold value for each Qwiic-enabled device that is attached whenever the I²C bus is polled.
Our software devs are looking at implementing the Bluetooth feature with the Apollo3 and Arduino core. ;) I am not sure of the specifics when this will happen for the OpenLog Artemis but we plan to upgrade the OLA to support wireless sensing in the coming months. =)
