🟠 OrangeTicker

Real-time BTC / SAT / XMR price ticker for the ESP32 Cheap Yellow Display

---

What it does

OrangeTicker displays live cryptocurrency prices on the ESP32-2432S028R (a.k.a. the Cheap Yellow Display), refreshed every 60 seconds from two independent sources.

Card	Currency	Displayed in
BTC	Bitcoin	USD · EUR · ILS
SAT	1 Satoshi	USD · EUR · ILS
XMR	Monero	ILS only

XMR is priced in ILS only — because that's the only thing that matters.

Prices are averaged between CoinGecko and Kraken for resilience. ILS rate is fetched from CoinGecko directly, with Frankfurter API as fallback.

Installation

Requirements

• VSCodium or VS Code with PlatformIO IDE extension
• ESP32-2432S028R board
• USB cable

1. Clone or download

git clone https://github.com/Vagalam88/OrangeTicker.git
cd OrangeTicker

2. Open in VSCodium / VS Code

File → Open Folder → select the OrangeTicker/ directory.

PlatformIO will automatically detect platformio.ini and download all dependencies (~2 min on first open).

3. Build & upload

Click the → (Upload) button in the PlatformIO status bar, or run:

pio run -t upload

4. Connect to WiFi

No credentials to edit in the code. On first boot, the device opens a WiFi access point named OrangeTicker-Setup:

1. Connect your phone/computer to that network
2. A configuration page should open automatically (captive portal); if not, visit http://192.168.4.1
3. Select your WiFi network and enter its password
4. The device saves the credentials and reconnects automatically on every future boot

To reconfigure WiFi later (e.g. switching networks): hold the BOOT button for 3+ seconds while powering on. This clears the saved credentials and reopens the OrangeTicker-Setup portal.
