# Bitcoin Dashboard for Elecrow 7-inch HMI Display
|
||||
|
||||
A real-time financial dashboard displaying cryptocurrency, precious metals, stocks, and market indices on the Elecrow 7.0-inch ESP32 HMI Display.
|
||||
|
||||
## Hardware
|
||||
|
||||
- **Display**: Elecrow 7.0-inch ESP32 HMI Display (Advance series)
|
||||
- **Resolution**: 800x480 RGB parallel interface
|
||||
- **Touch**: GT911 capacitive touch controller
|
||||
- **MCU**: ESP32-S3 with N4R8 module (4MB Flash, 8MB PSRAM)
|
||||
|
||||
## Features
|
||||
|
||||
- Real-time price data from Yahoo Finance API
|
||||
- Auto-refresh every 5 minutes
|
||||
- Touch to manual refresh
|
||||
- WiFi credentials stored in persistent memory
|
||||
- Antialiased fonts (DejaVu family)
|
||||
|
||||
## Displayed Assets
|
||||
|
||||
| Column | Assets |
|
||||

## Software Stack
|
||||
|
||||
- **Framework**: Arduino (PlatformIO)
|
||||
- **Display Library**: LovyanGFX v1.2.19
|
||||
- **Fonts**: DejaVu (antialiased)
|
||||
|
||||
## Building
|
||||
|
||||
```bash
|
||||
cd /home/chad/Documents/PlatformIO/Projects/bitcoin_dashboard
|
||||
pio run -t upload
|
||||
```
|
||||
|
||||
## PlatformIO Configuration
|
||||
|
||||
- **Platform**: espressif32@6.8.1
|
||||
- **Board**: esp32-s3-devkitc-1
|
||||
- **Partition**: huge_app.csv (3MB app, no OTA)
|
||||
- **Flash Mode**: QIO @ 80MHz
|
||||
- **PSRAM**: OPI (8MB)
|
||||
|
||||
## Data Source
|
||||
|
||||
Yahoo Finance API:
|
||||
```
|
||||
https://query1.finance.yahoo.com/v8/finance/chart/{SYMBOL}?interval=1d&range=1d
|
||||
```
|
||||
|
||||
### Symbol Mapping
|
||||
|
||||
| Display | Yahoo Symbol |
|
||||
|---------|--------------|
|
||||
| Bitcoin | BTC-USD |
|
||||
| Gold | GC=F |
|
||||
| Silver | SI=F |
|
||||
| MSTR | MSTR |
|
||||
| STRC | STRC |
|
||||
| NASDAQ | ^IXIC |
|
||||
| DOW | ^DJI |
|
||||
| S&P 500 | ^GSPC |
|
||||
|
||||
## Pin Configuration
|
||||
|
||||
### RGB Display Interface
|
||||
|
||||
| Signal | GPIO |
|
||||
|--------|------|
|
||||
| D0-D15 | 15, 7, 6, 5, 4, 9, 46, 3, 8, 16, 1, 14, 21, 47, 48, 45 |
|
||||
| HSYNC | GPIO 39 |
|
||||
| VSYNC | GPIO 40 |
|
||||
| DE | GPIO 41 |
|
||||
| PCLK | GPIO 0 |
|
||||
| Backlight | GPIO 2 |
|
||||
|
||||
### Touch Controller (GT911)
|
||||
|
||||
| Signal | GPIO |
|
||||
|--------|------|
|
||||
| SDA | GPIO 19 |
|
||||
| SCL | GPIO 20 |
|
||||
| I2C Address | 0x14 |
|
||||
|
||||
## WiFi Setup
|
||||
|
||||
WiFi credentials are stored in ESP32 preferences (persistent storage):
|
||||
|
||||
```cpp
|
||||
preferences.begin("wifi", true);
|
||||
preferences.putString("ssid", "your_ssid");
|
||||
preferences.putString("password", "your_password");
|
||||
preferences.end();
|
||||
```
|
||||
