This page is in progress and none of the code can be considered good or complete. I am just using this as an alternate storage of the code for right now.

I2C
X9241A - Digital Potentiometer
Detail on this page X9241A - Digital Potentiometer
There are basically only two functions that I am after right now which are both three byte instructions:
- Read WCR(Wiper Control Register) for the four potentiometers 0-3 (So far this is failing miserably)
- Send 1st byte - Address (my circuit - 01011010 or 0x2D)(binary - 0101 A3 A2 A1 A0) A values are actual pins set to high or low for an address.
- Send 2nd byte - Instruction (binary - 1001 (1/0)(1/0) 00) - The two bits are used to choose the potentiometer
- Read WCR requested Byte
- Write WCR for the four potentiometers 0-3 (This works)
- Send 1st byte - Address (my circuit - 01011010 or 0x2D)(binary - 0101 A3 A2 A1 A0) A values are actual pins set to high or low for an address.
- Send 2nd byte - Instruction (binary - 1010 (1/0)(1/0) 00) - The two bits are used to choose the potentiometer
- Send WCR Byte - Potentiometer value (binary - 00 D5 D4 D3 D2 D1 D0) - D values are the 0-63 potentiometer positions
Sample Code
Wire.beginTransmission(X9241_I2C_ADDRESS);
Wire.send(0xa0); //Instruction to write WCR-00
Wire.send(0x20); //Send a D value of 32
Wire.endTransmission();
DS1307 - Real Time Clock
The code for this very useful chip came from the RTC1307 - Real Time Clock
A/C_Control_v.01 code for Arduino
While this says v.01, don't count on it being a released v.01, I am still working on v.01, this is a back up
/*
* A/C Control v.01
* by <http://www.combustory.com> John Vaughters
* Credit to:
* Maurice Ribble - http://www.glacialwanderer.com/hobbyrobotics for RTC DS1307 code
*
* Turns on an LED for temperatures from analog pins 1-5 on
* digital pins 2-6 when the temperature rises above the THRESHOLDS 1-5.
* The program also implements a
* Serial Communication method that utilizes a leading CHAR for each command Described below.
* Commands:
* T(1-4) - Temp1-5 Status ex. T1, T2, etc
* C(1-4)(0-9) - Increment THRESHOLD1-4 by (1-9) ex. C15 increments THRESHOLD1 BY 5 (Note: C40 will give you a status of THRESHOLD4)
* D(1-4)(0-9) - Decrement THRESHOLD1-4 by (1-9) ex. D59 decrements THRESHOLD5 BY 9 (Note: D10 will give you a status of THRESHOLD1)
* A(0-1) - Manual AC on command A1 is AC on, A0 is AC off
* F(0-1) - Manual AC on command A1 is FAN on, A0 is FAN off
* B(00-59)(00-59)(00-23)(1-7)(01-31)(01-12)(00-99) - B(sec)(min)(hour)(dayOfWeek)(dayOfMonth)(month)(year) - B Sets the date of the RTC DS1307 Chip. ex. B1157193040209
* R(0-4) - Need to Define this better it is for transferring X9241 registers
* S - System Status
* Q(1-2) - (1) Memory initialize (2) RTC - Memory Dump

Summary
When Troubleshooting a multi-functional issue, it is best practice to break down the issue into pieces and test each piece as a separate system. However, we will first run through a quick test to see if we can find any obvious issues first.
