Story

This project will show you how to setup a live crypto currency tracker on an OLED display using a Raspberry Pi. I setup this tracker as an alternative to a specs display used in a custom Raspberry Pi case. I host a node for the Ravencoin network on my Pi, and I liked the idea of it also displaying current crypto prices. You can use the code for a variety of different OLED displays and this will work with any model Pi. This project uses python code to request data from a crypto currency price tracking API and display that data onto the OLED screen.

Code

Raspberry Pi Crypto Display

Line 9 is for your OLED model as supported by our Luma driver. Line 12(cryptos = ["eth", "rvn", "xmr"]) is what you will want to edit to change which crypto prices you want displayed. Lines 33-35 is where you would want to edit the spacing of the words on your display Line 36 will change the amount of time before changing the current displayed crypto.

def get_all_crypto_prices():
    usd = []
    
    for crypto in cryptos:
        price_usd = float (json.loads(requests.request("GET", crypto_url.format(crypto), headers=headers).text)["ticker"]["price"])
        usd.append(price_usd)
        
    return usd

def tick_display():
    global prices_usd
    
    for index, crypto in enumerate(cryptos):
        with canvas(oled) as draw:
            draw.text((30, 0), "Crypto Rates", fill="white")
            draw.text((55, 15), crypto.upper(), fill="white")
            draw.text((10, 40), "USD: {}".format(prices_usd[index]), fill="white")
            time.sleep(5)
