  • Why not put pictures of the winners and their bots next to the list of winners?

  • The full datasheet is up now. Thanks for updating!

  • No, you don’t have the data sheet posted. What your website claims to be a data sheet is actually the “preliminary data brief”; it is only four pages long, was written in Jan 2014, and doesn’t include the register map!

    The actual data sheet, available at http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00112632.pdf, was written on Aug 2014, is 74 pages long, and contains useful information not available in the data brief.

  • Please consider linking to the actual data sheet, rather than just the product brief.

    The datasheet is available here: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00112632.pdf

    A major point of interest that is deceptively challenging to find is how frequently the sensor may perform measurements. It seems as though there is a tradeoff as to whether one wishes to perform range measurements only, ambient light measurements only, or both.

    I’m interested in just range measurements. The minimum measurement period according to the datasheet appears to be controlled by the SYSRANGE__INTERMEASUREMENT_PERIOD register. At its fastest setting (setting this register to zero), the range measurement period (when in continuous range measurement only mode) is 10 ms.

    Note that this sensor’s max range (according to the datasheet) is only 10 cm, but Casey (from SF) reports he can get reliable measurements out to 25 cm. Also note this sensor uses IR, so it may not work very well outdoors.

  • What IMU are they using?

  • Seventhed. I need a higher resolution ADC and will have to buy from elsewhere.

  • Agreed, the Saleae website lists the Logic Pro 8 as having a digital sample rate of 500 MS/s and analog sample rate of 50 MS/s.

  • I have an old Saleae 16 and run the Saleae Logic application. The program runs fine on my MacBook Pro.

    You really need to use a mouse when using the Saleae Logic application, the mouse wheel is used to zoom in/out.

  • lower heat dissipation (so they can make the device that size) and low power. i suspect that metal housing serves as a heat sink (in addition to reducing spurious emag emissions).

  • ditto. nkcelectonics breaks out IO, provides a configurable bus (3.3 or 5v), and is overall far better designed.

No public wish lists :(
