I updated the circuit to fix the short. I attached a picture of the update, one of a general overview of the setup and one of the evaluation board where the chip is held.
Still a solid light on & still cant find it with the scanner. I do not have any other I2C devices but I ordered some other digipot's that are I2C and they should be here today to try, particularly the AD 5171.
I tried another string of I2C scanner code in case their was something wrong with the first but it did the same thing. It just said "Scanning.." and nothing came up.
From the picture showing where the chip was held I used a fluke 189 meter and did a continuity check between each of the pins that come off of the chip and found where it correlates (beeps) to a connection on the evaluation board. You can visually see from the overview where they are connected.
From the spec sheet it indicated the dot on the chip identifies Pin 1. Moving down are pins 2,3 & 4. Then starting from the top of the chip on the opposite side of the dot is 8 and moving down are pins 7, 6, 5. At least that is my understanding from the spec sheet.
I linked the wrong evaluation document yesterday... The one I have been using I will attach in a minute. It is Analog Devices document UG-395.
The software is using address "44". The spec sheet for the AD 5273 says the slave address byte is 010110ADO0 which should come out to 44 right? Even if it was wrong the I2C scan should still pick up the chip and say what address it is though I thought?
