This process is known as the stellar consensus protocol (SCP). Instead of relying on more energy-intensive methods like Proof-of-Work (PoW), which Bitcoin uses, Pi secures its ledgers using a peer validation process. The Pi Network works by using a simple consensus method where smartphone users can vouch for each other as being trustworthy. Also, while mining popular cryptocurrencies like Bitcoin (BTC) or Ethereum (ETH) is daunting for most people, the Pi Network aims to make crypto-mining as effortlessly simple as possible. Like most cryptocurrencies, the Pi coin isn't run by a bank, government or any centralised entity. As of March 2022, the total user base officially surpassed 33 million. Just a few months after launching on March 14 of that year, the Pi Network grew to over half a million users. Pi was founded back in 2019 by four Stanford graduate students: Nicolas Kokkalis, Chengdiao Fan, Vince McPhilip, and Aurélien Schiltz. The Pi Network is a blockchain network that allows anyone to mine cryptocurrency (in this case, the Pi coin) on their smartphones. Here's what you need to know about the Pi Network, its Pi Network coin, whether it's legitimate, and how it operates. Many have even claimed that the Pi Network is a scam. However, that hasn't stopped it from attracting its fair share of controversy as well. One blockchain project that's trying to make crypto mining as easy as possible, especially for non-crypto veterans, is the Pi Network.ĭespite being newer to the crypto scene, the Pi Network has attracted a noticeable fanbase since its founding in 2019. test-image.py howchoo-low-res-h.pngįor best results, you'll want to use an image that's the same aspect ratio as your panel or else build some cropping functionality into the script.There are tens of thousands of cryptocurrency projects in existence, although most struggle to get enough attention from the non-crypto community. Now make the script executable: chmod +x test-image.pyĪnd run the script passing in your image as an argument: sudo. Image.thumbnail((matrix.width, matrix.height), Image.ANTIALIAS)

Feel free to create a working directory of your choice, but I'm going work right out of the home directory: cdįirst, you need to download a sample image: wget Give this a shot to make sure everything is set up correctly.įor this example, you'll work from another directory. Finally, for this particular sample script, we can pass in the text we want to scroll with -text. And, because we're using the adafruit bonnet, we need to specify the hardware with -led-gpio-mapping=adafruit-hat.Then, because the default display size is 32x32 and my panel is 64x32, I'm passing in -led-cols=64 to override the number of columns.We're calling this script with python3 because that's how we built the library. You must be in the samples directory for the fonts to load properly. Note: Some of the sample scripts are a little bit feeble. Now run the following command: sudo python3 runtext.py -led-cols=64 -led-gpio-mapping=adafruit-hat -text="Hello, world!" Navigate to the samples directory: cd bindings/python/samples You're going to use a Python script called runtext.py that scrolls text across the screen on repeat.

The library ships with some sample code to get us started.

With our hardware set up and the software installed, let's run a simple test.
