Part Number: LDC1614EVM
Having difficulty integrating the LDC1614EVM to my Arduino Uno. Reading in the forum " LDC1614EVM + Arduino + I2C issues", I tried to follow the instructions but all the output are still zero's.
Thank you Kylie Chesner for all your contribution.
Using high quality jumper wires (not soldered) I have connect the following:
1. I have connected the LDC1614EVM's SDA and SCL to the Arduino 3.3V I2C bus using 4.7K Ohm pull-up resistor.
2. INTB floating
3. GND on the LDC1614EVM NOT connected
4. SD, ADDR to GND.
I used the Sketch provided in the following link, but all I see are zeros. e2e.ti.com/.../1882677
I am interested in obtaining the "raw Data" as demonstrated in the GUI Tool v 1.9.1 (rev B) on my PC. I have purchased a PC laptop just to run GUI Tool, but am using a Mac Book Pro to run my Arduino.
Eventually I will also be connecting my Arduino to the FDC2214EVM Capacitive Sensing to obtain the same raw data.
Please excuse the elementary questions but I am new to Micro-controllers and programming.
Thank you for your time.

In reply to Alexander Luis:
This application sounds very challenging especially considering the 1m^3 chamber and the 6mm plastic BB. The response from the plastic pellet will likely be very small if noticeable at all from the noise floor. Also note, the faster you sample the less resolution you get. I would say that unless you can increase the size of the pellet or make the chamber much smaller it will be very difficult to accurately sense the location. If you already have the setup you can verify the response you get by using the FDC2214EVM and the Sensing Solutions GUI to stream the data.
Thank you again for responding. I will change the BB pellet to a 4.5 mm copper pellet BB.
I have also decided to purchased a PC in order to run your GUI (save my MacBook Pro), in addition to purchasing your LDCCOILEVM.
The following LDCCOILEVM spiral coils K ( 29mm,30 turns, 8mil trace, 6mil space, 4 layers), spiral coil J ( 29mm, 35 turns, 6mil trace, 6mil space, 2 layers) and stretched rectangular coil A ( 100 x 15 mm, 23 turns, 6mil trace, 6mil space, 4.06mm loop stepping, 4 layers ) are attached to perpendicular walls . The 4.5 mm copper BB pellet will be droped and I hope to obtain the values from respective coil sensors.
Can you recommend a capacitor valuethat I may purchase (I'm doing a proff of concept ) , focusing on sensitivity?
I'm aware the capacitors are surface mounted, and plan to purchase them from Jamaco Electronics.
Thank you very much for your time and efforts.
