RTC2Xbox

RTC2Xbox is inspired and based on spi2par2019 by Ryzee119.
It's a LCD mod for the original Xbox without modchip.

New Features!

• Display date and time with real time clock.
• Display temperature ambient from a thermistor.
• Display voltages 3.3v 5.0v 12.0v

Note

• Delay for displaying fan speed, temp° of CPU, M/B and resolution is 2 secs to 30 secs for first time.
  And the next times is 2 secs to 10 secs. It's depend of the SMBus if is busy or not.
• Contrast and backlight are controlled by only one potentiometer in same time.

Software Installation

RTC2Xbox uses the open-source Arduino Software (IDE):

• Download the Arduino IDE And install it!

LiquidCrystal Library Open the IDE and click to the "Sketch" menu and then Include Library > Manage Libraries.

1. In Filter your search... enter LiquidCrystal install it or update it.
2. In Type select updatable and update all libraries which would appear.

RTC2Xbox Library

• Clone this repository to your PC
• Or Download Zip
  Extract to rtc2xbox or rename rtc2xbox-master to rtc2xbox

RTC Installation & Programming

1. Connect Slave (Pro Micro) to RTC DS1307
   
   
   
   
   

2. Program Slave (Pro Micro), open /rtc2xbox/rtc2xbox_slave/rtc2xbox_slave.ino with Arduino IDE.
   Uncomment below, if you want force adjust date time. Only set the datetime one time.

   // #define FORCE_ADJUST_DATETIME

   for

   #define FORCE_ADJUST_DATETIME

   and ajust time at line 30. You can add 30 sec for compiling and uploading.

   uint8_t hour  =   11; // 0-23
   uint8_t min   =    0; // 0-59
   uint8_t sec   =    0; // 0-59
   
   uint8_t day   =   10; // 1-31
   uint8_t month =   10; // 1-12
   uint16_t year = 2020; // 2000-2099

3. Set the Board Type the Arduino Leonardo and the port correctly.
   
   
   
   
   

4. Compile by clicking the tick in the top left.
   Check the console output it has compiled successfully

5. Connect a Micro USB cable between the Slave (Pro Micro) and the PC.

6. Click the upload button and confirm successful.

7. Disconnect Slave (Pro Micro)

   • comment #define FORCE_ADJUST_DATETIME. Remember, only set the datetime one time.

     // #define FORCE_ADJUST_DATETIME

---

8. Program Master (Pro Micro), open /rtc2xbox/rtc2xbox.ino with Arduino IDE.
   Uncomment below to make the in-game temp readouts display in Fahrenheit.

   // #define USE_FAHRENHEIT

   for

   #define USE_FAHRENHEIT

9. Compile by clicking the tick in the top left.
   Check the console output it has compiled successfully
10. Connect a Micro USB cable between the Master (Pro Micro) and the PC.
11. Click the upload button and confirm successful.
12. Disconnect Master (Pro Micro)

Hardware Installation

1. Connect Master (Pro Micro) to LCD, Potentiometer and Thermistor (Optional)
   
   
   
   
   
2. Connect Master (Pro Micro) for voltages reading
   
   
   
   
   
3. Connect Master (Pro Micro) to Slave (Pro Micro)
   
   
   
   
   
4. Connect Master (Pro Micro) to Xbox LPC
