So when I was looking up tutorials for my own benefit for Threading, the main one I came across was so impossibly dense, that I was taken aback. If you want your currency, change GBP to USD or other currency, but check what Bitstamp calls it before doing so or the script won’t recognise it.Īlso be sure to keep the (device), as this tells Python which screen to send the information to. Then in the canvas, you’re going to want to change the BTC to ETH or LTC (or whatever else is available on Bitstamp) and also the indicated name on the third row.įill=”white” is simply to tell the OLED that the screen needs to make the font white, or it’ll come out the default on a black background.

You can name these whatever you like, but the rest of my code relies on these names so be sure to change things below if you’re deciding to rename the definitions. Now this line of code is actually integrated with the fetching loop above, so we can simply just change the definition name to what we want and the chosen cryptocurrency.ĭef btc to def eth or def ltc to tell Python it’s a different definition and loop. To center it, just take five from each of the designated numbers. But if you change the ((0,10)) or any of the numbers, you can move it up and down the screen as you see fit. We do that by treating it as a ‘canvas’ and we’re going to ‘draw’ on it, while also putting it into the right places on the screen.ĭraw.text((0, 10), “PCG Ticker”, fill=”white”)ĭraw.text((0, 20), “Bitcoin”, fill=”white”)ĭraw.text((0, 30), rows, fill=”white”)ĭraw.text((0, 40), rows, fill=”white”)ĭraw.text((0, 50), rows, fill=”white”)Īs the screen is only five rows tall, we’re going to fill it up with information and leave the top blank. Now we’re actually going to code the OLED to take the data and present it on screen. Here, we’re not only fetching the currency, but we’re also slotting it into three rows, with a 24 hour high, lowest and at the top, its current value. ‘’.format(crypto_currency, fiat_currency, data), Print(“error fetching from Bitstamp API”)ĭef price_text(crypto_currency, fiat_currency):ĭata = fetch_price(crypto_currency, fiat_currency) Now we have the method of grabbing data from the web, we’re going to actually grab the ticker and tell Python what we want to display it as, while also giving us an error if (and probably when) Bitstamp goes down:ĭef fetch_price(crypto_currency, fiat_currency):īitstamp_api = “” + crypto_currency.lower() + fiat_currency.lower()

Run ‘sudo -H pip3 install requests’ to install it.”) Print(“The requests library was not found.

Here, we’re going to be importing the requests library, but also using the Luma script’s method of immediately killing the script if it can’t find the library – in the event we move the script to another Pi or do a fresh install.

I’m by no means any good at coding, I just know how to make things legible – I hope. However, I found the code messy and decided to do my best to clean it up. So this script I’m using is adapted from the Luma.OLED library, which comes with a few examples – including a Bitcoin Ticker. We’re going to come back to the LCD later on when we start working on the Raspberry Pi, so don’t worry about connecting it up just yet. If you’re still unsure, here’s what each pin on your LCD actually means: The ones I have actually indicate where the LED backlight is supposed to be plugged into, so work backward from there. If you’re having to connect the controller, plug it into a breadboard and connect each pin via a jumper wire to each matching pin on the LCD. Converting the 12 wires to 4 and then into the Pi just gives us a lot more flexibility – figuratively and literally.

I made my life a million times more difficult and bought one without the controller, so had to attach one separately onto the back via jumper wires which in the long run made things a lot easier on us wiring this thing up to the Raspberry Pi. However, if you wanted to, it’s quite easy to fit it together. I’d highly recommend the last one, it makes life so much easier and means you won’t have to buy multiple pieces or spend time soldering the screen together with the screen. The 1602 LCD can come in three varieties, one without a header pin, with headers already soldered on, and a version with the controller soldered on, which also includes a contrast toggle. Incredibly common around maker spaces, the 1602 LCD can display two lines of sixteen characters, it looks a little intimidating when you have to wire one up for the first time, but we’re going to ignore 4 of the 16 pins for this project and actually take a small shortcut to make things easier.
