Page 5: Getting Started
The balance of this document identifies and describes the controls available on the GUI. In combination with the TCS3701 datasheet, the QSG and application notes available on the ams website, there should be enough information to allow evaluation of the TCS3701 device. -
Page 6: Hardware Description
Hardware Description Hardware Description The hardware consists of the EVM Controller, the TCS3701 EVM daughter card, and a USB interface cable. The EVM controller board provides power and I2C communication to the daughter card through a seven pin connector. When the EVM controller is connected to the PC through USB, a green LED on the board flashes once on power up to indicate the system is getting power. -
Page 7: Software Description
Document Feedback TCS3701 Software Description Software Description The main window (Figure 3) contains the system menus, system level controls, device information and logging status. The ALS tab contains controls for the light sensing function. The Prox tab contains settings for the proximity function. The application polls the ALS and proximity raw data continuously and calculates the Lux, CCT, and prox standard deviation values. -
Page 8: System Menus
Document Feedback TCS3701 Software Description If the EVM board is disconnected from the USB bus while the program is running it displays an error message and then terminates. Reconnect the EVM board and restart the program. System Menus At the top of the window there are pull-down menus labeled “File”, “Log”, and “Help”. The File menu provides basic application-level control. - Page 9 Document Feedback TCS3701 Software Description 4.2.2 Log Menu The Log menu is used to control the logging function and to save the log data to a file. Log data is accumulated in memory until it is discarded or written to a data file.

TCS3701 device. The Power On checkbox controls the PON function of the TCS3701 . When this box is checked, the power is on and the device can operate. When this box is unchecked, the power is off and the device does not operate (The control registers can still be written, but the device does not function). -

Page 12: Als" Tab
Document Feedback TCS3701 Software Description “ALS” Tab The main portion of the screen contains a tab labeled ALS. The controls in this tab are divided into 3 sections, each performing a separate function. Figure 9 : ALS Tab 4.7.1 ALS Controls The left side of the ALS tab contains controls to set various ALS settings. - Page 13 PC and polling rate of the GUI program, the GUI does not display every sample, since the actual TCS3701 is operating faster than the GUI can display and log the data. This is not normally an issue, since the operating environment is not rapidly changing. The Raw FIFO Log is a special function that is designed to capture all of the ALS Data for Channels 0 and 1, without skipping any data.

Page 15: Prox" Tab
“Prox” Tab The main portion of the screen contains a tab labeled Prox. The controls on this tab control the operation of the Proximity function of the TCS3701. Demo Kit Manual • PUBLIC UG000418 • v1-00 • 2019-Jan-11... - Page 16 Document Feedback TCS3701 Software Description Figure 11 : Prox Tab 4.8.1 Prox Controls The left side of the Prox tab contains controls to set various Prox settings. The PPULSE controls the number of pulses used for each prox cycle. The number of pulses is the PPULSE value plus 1 and is displayed immediately to the right of the box.
- Page 17 15 consecutive proximity values out of range Information The Offset Range Extension feature of the TCS3701 is known to cause the PDATA values to drift over time. Use of this feature IS NOT recommended. The Enable control in the Offset range extension group box enables the coarse offset range when checked.
- Page 18 Document Feedback TCS3701 Software Description The Disable APC control disables the automatic pulse control (APC) function. When this function is active, the range of the PDATA value is 0-1023. The Dropdown control in the Prox Filter group box enables and disables the Proximity Filter. This causes a running average of 1 (Disabled), 2, 4, or 8 samples to be reported in the PDATA register.
