ESP8266 Cryptocurrency Ticker & Portfolio Tracker, with SPI TFT display, and IR functionality.
ESPIR is an ESP8266 powered Crypto Ticker and Portfolio Tracker that uses a TFT screen to display statistics and a candle chart for various cryptocurrencies, as well as a configured portfolio. It utilises an IR remote for configuration and user input. This device is powered by the CoinGecko API.
ESPIR Lite is a simplified rewrite of my previous ESPIR repo, prioritizing reliability and portability while adding support for more displays and ESP32 usage.
| New | Gone |
|---|---|
| Support for more ST7735/ST7789 displays | Removed 4 coins with small graphs representation |
| Support for ESP32 as well as ESP8266 | Removed ability to replace coins with new ones (short on EEPROM) |
| Up to 20 coins allowed in portfolio at any time | |
| Selection of up to 20 coins in coin display | |
| Updated to current top 20 coins (no wrapped coins) | |
| Uses hardware SPI for increased display refresh rate | |
| Improved WiFi setup functionality (auto-detect access points, only needs password now) | |
| More free heap so far more reliable | |
| Updates prices every 60 seconds, as price updates on API are about this frequent (and less chance of rate limits) | |
| Built on my TFT Menu Arduino library |
Arduino Boards Manager- ESP32 Boards : Version 2.0.18
Arduino Boards Manager- ESP8266 Boards : Version 2.7.4
ArduinoJSON: Version 7.1.0Adafruit ST7735 & ST7789 Library: Included in this repo, copy into your libraries folder (uninstall existing version if already installed)IRremote: Version 4.4.0Adafruit GFX Library: Version 1.11.3 (updating to latest makes text drawing really slow?)
- Compatible ESP8266/ESP32 board (see below)
- Compatible SPI TFT display (see below)
- IR Reciever / Remote
- ST7735: 128x128, 160x80, 160x128
- ST7789: 240x240, 320x240
- ESP32: WROOM, C3-ZERO
- ESP8266: NodeMCU, D1 MINI
- Install Arduino, and install all dependencies listed in Libraries/Requirements
- Put the ESPIR_Menu and modified Adafruit_ST7735_and_ST7789_Library directories in your Arduino libraries directory
- Open the ESPIR_lite_ESPX.ino file in the ESPIR_Sketch_ESPX directory in Arduino (where X is 32 or 8266 depending on the board you are using)
- At the top of the file, first change the pin definitions to match your board (see Displays in Configurations section)
- Once changed, change the TFT definition to match your display (see Microcontrollers in Configurations section)
- Select the correct board in the board manager (see Microcontrollers in Configurations section - if not installed, install the ESP32 board manager URL)
- Upload the sketch to your board
In each of the following configurations, the TFT init code within ESPIR_Sketch.ino will need to be replaced with the specified TFT code.
TFT tft = TFT(ST7735_SPI_128_128, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7735_SPI_160_80, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7735_SPI_160_128, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7789_SPI_240_240, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7789_SPI_320_240_INVERT, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7789_SPI_320_240, TFT_CS, TFT_DC, TFT_RST);
TFT tft = TFT(ST7789_SPI_320_240, TFT_CS, TFT_DC, TFT_RST);
In each of the following configurations, the pin definitions will need to be changed to match the microcontroller.
