Firmware samples - GitHub

The evaluation board contains the following sensors from AMS-Osram: TMF8828 (a direct time-of-flight (dToF) sensor), AS 7331 (a low-power, low noise integrated UV sensor), AS 7343 (a 14-channel highly versatile, multi-purpose spectral sensor) on a single PMOD enabled board that is compatible with the Renesas QC-IoT System and QC-Studio.

The PMOD board is compatible with the MCUs part of the QC-IoT like the RA2E1 and RA6M4 and can be daisy-chained with other PMOD sensor modules.

The TMF8828 is a direct time-of-flight (dToF) sensor in a single modular package with associated VCSEL. The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4, 3x6 and 8x8 multizone output data and a wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8828 provides distance information together with confidence values on its I2C interface.

The AS7343 is a 14-channel highly versatile, multi-purpose spectral sensor enabling new consumer, commercial, industrial and laboratory applications. It is optimized for reflective, transmissive and emissive measurements including color matching, fluid or reagent analysis or general spectral reconstruction.

The spectral response is defined by individual channels covering approximately 380 nm to 1000 nm with 12+2 channels: 12 in the visible spectrum (VIS) to near-infrared (NIR) range, a clear channel and flicker channel. Applications can be assisted by full spectral reconstruction of light and an integrated flicker detection channel that can automatically flag ambient light flicker at 50/60 Hz as well as buffer data for externally calculating other flicker frequencies.

AS7343 integrates high-precision optical filters onto standard CMOS silicon via deposited interference filter technology. A built-in aperture controls the light entering the sensor array to increase accuracy. A programmable digital GPIO and LED driver enable light source and trigger/sync control. Device control and spectral data access is implemented through a serial I²C interface. The device is available in an ultra-low profile package with dimensions of 3.1 mm x 2 mm x 1 mm.

The AS7331 is a low-power, low noise integrated UV sensor. The three separated UVA, UVB and UVC channels convert optical radiation signals via UV optimized photodiodes to a digital result and realize a continuous or triggered measurement. The irradiance responsivity can be adjusted via Gain, conversion time and internal clock frequency to effect sensitivity, full scale range and LSB. The AS7331 detected amount of radiation in the set Gain and conversion time configuration will be provided as digital counts by the AS7331. The AS7331 offers a range of 12 Gain steps by a factor of two for each step. The conversion time is internally controlled over a wide range of 15 steps by a factor of two for each step. With the input pin (SYN), the conversion time can be externally controlled to adapt the measurement to the given environment and time base.

With its irradiance responsivity factor and conversion time, the AS7331 supports an overall huge dynamic range up to 3.43E+10 (resolution multiplied by gain range). It achieves an accuracy of up to 24-bit signal resolution (internal via I²C and shifter 16-bit), with an irradiance responsivity per count down to 2.38 nW/cm² at 64 ms integration time. Via an integrated divider, the 16-bit I²C output can be adjusted to the significant bits of interest.
