FDC1004EVM

User's Guide SNAU163C – August 2014 – Revised October 2016 FDC1004EVM User's Guide The FDC1004EVM evaluation kit is a plug and play system to test and evaluate the FDC1004, 4-Channel capacitive to digital converter. The EVM is a breakable PCB which consists of 3 sections. The first section is a USB to I2C converter based on MSP430F5528 micro-controller, the second section contains the FDC1004 and the third section is a touchless sensor (to demonstrate the sensitivity of the FDC1004) . The third section can be removed and replace with customized sensors to evaluate the capabilities of the FDC1004 in various applications. The FDC1004EVM can be used with the Sensing Solutions EVM GUI. The software is able to configure the FDC1004’s registers, graph the measured values, and export the data in CSV format. The EVM contains one FDC1004 (See Table 1). Table 1.

USB to I2C section: this has the purpose to interface the communication of FDC1004 to a USB port. 2. FDC1004 section: this section embeds FDC1004 capacitive to digital converter. 3. Sensor section: this section contains a capacitive sensor that can be used for both human proximity and simple gesture recognitions.. The EVM has precut lines on the borders of each section that allow for a flexible and specific system design. As an example of the flexibility of this design, the sensor can be replaced with a customer sensor, or the MCU section can be separated to allow for a remote placement of the FDC1004. USB to I2C FDC1004 SENSOR Figure 1. FDC1004EVM : Sections 1.2 Input/Output Connector Description J1, J2: 4x1 Header: the I/O ports of sections between the USBtoI2C and the FDC1004 sections. This provides the I2C communication channel and the power connections between these two sections should the EVM be separated into sections. A simple 4 wire cable can be used to interface the sections. Table 2.

Configuration Page The FDC1004 measures in a round robin mode and can make up to four measurements. If all four measurements are enabled and the sample rate is 400 samples per second new data for all four measurements would be available at a rate of 100 Hz. If a single measurement were enabled rather than all four, again with the sampling rate set to 400 samples per second, new data for the single measurement would be available at a rate of 400 Hz. To make a single measurement only once, select the measurement channel and click "Take Measurement". This will disable the "Enable continuous multi-channel measurements" setting. Continuous measurements must be enabled for the data streaming function of the GUI and EVM. Please reference the FDC1004 datasheet for more information regarding individual measurement settings. 2.8 Streaming Measurement Data The Sensing Solutions GUI and EVM provide a tool to capture, display, and log measurement data. The section describes how to use the data measurement tools from the "Data Streaming" page accessible from the GUI menu. 2.8.1 Choosing the Graph and Visible Channels Select the drop down menu on top of the y-axis to choose the graph to display.

Graph Configuration Button on Data Streaming Page The configuration window displays the actual frame rate of the graph, the rate at which data is added to the graph, the vertical scaling, and the sample buffer size. The display rate is the rate at which the graph updates on the computer display and is not configurable. It is automatically optimized by the GUI. The "New Data Sample Rate" allows the user to choose when new data is added to the graph. Selecting "EVM Output Rate" will display data on the graph as fast as is available from the EVM. This should not be confused with the actual sampling rate of the device on the EVM which could be different. The "Add sample to graph every ... ms" will add a new sample to the graph at the specified rate. The "Verical Scaling" allows the user to either manually set the minimum and maximum values of the yaxis on the graph or use auto-scaling. The "Autoscale & Lock" button scales the graph based on the data of the current display and then locks those vertical scaling settings. The "Sample Counts" allows the user to specify the number of samples displayed on the graph and the total number of samples stored in the buffer. Please note the buffer size does not affect data logging to a file. To hide the configuration window, click the "Hide Graph Configuration" button. 32 FDC1004EVM User's Guide SNAU163C – August 2014 – Revised October 2016 Submit Documentation Feedback Copyright © 2014–2016, Texas Instruments Incorporated Sensing Solutions EVM GUI www.ti.com Figure 34.

Firmware Upload Success 3 Board Layout Figure 42 and Figure 43 show the board layout of the FDC1004EVM. Sensor layout has been designed to demonstrate the possible trade-off between sensor sensitivity and protection from interferences. SHLD1 surrounds "LEFT" sensor and it has a bigger area than SHLD2 that surrounds "RIGHT" sensor. As a consequence, the "LEFT" sensor is better shielded from interferences but at the cost of lower sensitivity. Figure 42. Top Layer Routing Figure 43.
