# BitClock
E-Paper Bitcoin trading/stats display.
## Setup
### Hardware
ESP32 ([WEMOS LOLIN D32](https://www.wemos.cc/en/latest/d32/d32.html) in my case)
Waveshare E-Paper display ([4.2 Module](https://www.waveshare.com/wiki/4.2inch_e-Paper_Module))
Wiring (Set in `epdif.h` from Waveshare libs):
```c
#define RST_PIN 0
#define DC_PIN 4
#define CS_PIN 5
#define BUSY_PIN 2
```
Wire DIN/CLK to your SPI port, for me this is MOSI(23) and SCK(18)
I powered the display from the 3.3v rail of the board.
### Dependencies
Add [ESP32](https://github.com/espressif/arduino-esp32) board to Boards Manager
Download [Waveshare](https://github.com/waveshare/e-Paper) libs and copy `Arduino/EPD4in2` to `Arduino/libraries`
Install `NTPClient` and `ArduinoJSON` in "Library Manager"
## Config
Copy `Config.hpp.example` to `Config.hpp` and enter WiFi details and any other changes you like.
Open `BlockClock.ino` with Arduino IDE and select your board.
Upload!
## TODO
- Add webserver for configuration
- Abstract Arduino specific code
- Make Linux version (Raspberry PI etc)
- Make display emulator
- Add more content from multiple sources
- 3D printed case design
