• Vendors Still Allow You to Hack Their Vending Machine

• Read credit on load
• Press <- left, load .bin dump from storage
• Press -> right, dump EEPROM .bin to storage /ext/app_data/coffee_eeprom
• Hold . center, Enter credit editor mode
  • <- -> to move the digit cursor
  • up/down to increase/decrease the digit value (min 0.01 max 655.35)

• SDA -> Pin 15
• SCL -> Pin 16
• VCC (3.3V) -> Pin 9
• GND -> Pin 18

Provide two 4k7 ohms Pull-Up resistors from SDA to VCC and one from SCL to VCC

The upper 6 pins male header is not required (unless you want to use the PicKit2 either)

• Write .bin dump loaded from file
• Set any amount (see CoffeeEditor)
• Threads for better UX (ex loading bar)

I am not responsible for any illegal use of this tool. Edit the credit is like stealing.
