Such as:Īfter really digging into the examples I figured out how to get the Grid-EYE and 1-Wire to work but I still can’t get the MAXREFDES130# to work. Also, there is plenty of technical information on these boards and their integral parts from a design perspective, but documentation that would be helpful in the development stage was lacking. It seems my Arduino IDE kept updating the stock 1-Wire libraries which are incompatible with the Grid-EYE Demo supplied. To be brief – during the unboxing I had problems getting the firmware going. I think Maxim has the right idea using Panasonic’s Grid-EYE as the sensor in combination with bringing 1-Wire switches and controllers to the Arduino platform. And having a Grid-EYE on a 1-Wire interface is probably the most fun way I can think of to learn how the 1-Wire protocol works. That being said, it isn’t a useless product by any means. Unfortunately I found the Grid-EYE to be completely useless through glass. The main goal of this review was to determine if the Grid-EYE sensor could work through panes of glass and if so how well. In spite of the kinks this RoadTest was enjoyable as well as challenging. I have learned much about this product and myself as a result and I am truly grateful.

This challenge was as much of a RoadTest for me and my skills as it was for the package they sent me. I am honored that Element 14 and Maxim Integrated chose me to Road Test these boards. What were the biggest problems encountered?: Specifications for the reference board and pinouts not provided. What other parts do you consider comparable to this product?: null RoadTest: 1-Wire® Grid-EYE® Sensor w/Arduino-Compatible PCBĭid you receive all parts the manufacturer stated would be included in the package?: True
