APPLICATION INFORMATION

VEML7700 is a cost effective solution of ambient light sensor with I2C bus interface. The standard serial digital interface is easy to access “Ambient Light Signal” without complex calculation and programming by external controller. 1. Application Circuit Fig. 9 - Application Diagram Notes For detailed descri ption about set-up and use as well as more applicatio n related information see AN : “Designing VEML7700 into an Application” 2. I2C Interface The VEML7700 contains actual six 16 bit command codes for oper ation control, parameter setup, and result buffering. All registers are accessible via I2C communication. Fig. 10 shows the basic I2C communication with VEML7700. The built in I2C interface is compatible with I2C modes “standard” and “fast”: 10 kHz to 400 kHz. I2C H-level range = 1.3 V to 3.6 V. Please refer to the I2C specification from NXP for details. Fig. 10 - Send Byte / Receive Byte Protocol Register Addresses VEML7700 has actual six user accessible 16 bit command codes. The addresses are 00h to 06h (03h not defined / reserved). Device Address The VEML7700 has a fix slave address for the host programming and accessing selection. The slave address (7 bit) is set to 0010000 = 0x10. The least significant bit (LSB) defines read or write mode. According 8 bit the bus address is then 0010 0000 = 20h for write and 0010 0001 = 21h for read. Auto-Memorization VEML7700 can memorize the last ambient data before shutdown and keep this data before waking up. When VEML7700 is in shutdown mode, the host can freely read this data via read command directly. When VEML7700 wakes up, the data will be refreshed by new detection.
