On reading about the Revoke article 50 ePetition at the weekend and as its a hot topic at the moment, I thought I would write something to pull the data and breakdown where the signatures were coming from. The petition data is available as a JSON file. I was going to do this in PERL, […]Read more "Scraping www data with Python"
We have just installed a Laird Sentrius RG1xx and have a wind meter on test in Roslin. Its data feed can be seen here. wm868v1 Data Feed MyDevices.com data visualisation. You should see Wind speed and direction charts on clicking the link. Using Swagger on TTN How we can use TheThingsNetwork(TTN) to develop our sensors and […]Read more "Testing a wm868v1"
We have made several updates to the component layout, adding a second set of pins on the opposite side to the 40 pin connector. This distance is an integer alignment of 2.54mm pitch, making it easy to use for extended prototyping. The entry power routing has been revamped with options for solder bridging the 3v3 […]Read more "cAno2.1"
http://www.thewindop.com new LoRaWan wind meter is under test. This post deals with how to visualise data for debug/interest during the early days of using sensors on TheThingsNetwork(TTN). Firstly you need a TTN account with data being streamed to the site. You also need to enable SWAGGER which will let you pull up to a weeks […]Read more "cAno2, LoRa & TheThingsNetwork"
http://www.thewindop.com‘s latest wind meter now has LoRa capability. It can operate from batteries or with an optional solar panel, dependent on deployment requirements. It uses our cAno2 data sampler, more details here. Our prototype LoRa version will be available for pre-order on the 1st December with the specification outlined below. MCU MSP430FR5994 256KB FRAM, 8KSRAM […]Read more "LoRa cAno2 windmeter"
We have built cAno2 based on the excellent MSP430FR5994. Designed for long term data collection in the big outdoors, it has BLE to allow easy configuration. An outline specification listing can be found below. The 256KB of FRAM on the MSP430FR5994 can be shared between the data and program, storing to SD card or using one of […]Read more "cAno2"
In this brief post we will cover connecting an I2C compass sensor to Arty, specifically an HMC6352. The outcome is to demonstrate how to use the I2c function calls to read data from an I2C device. See previous posts for details on the platform used, but in practice the C code can be used with any […]Read more "Connecting an I2C compass to Arty"
In this post we will provide an overview of the system used in the subsequent ARTY posts to check we can communicate with various peripherals. All scripts and c code for these examples can be found at https://github.com/thewindop/fpgaArtyExamples All FW is derived from the Xilinx examples which can also be used to expand your own […]Read more "Arty microblaze example"
