===============
|
||
|
|
|
||
|
|
Every once in a while we come across sensors that will not pair well with
|
||
|
|
a specific board. This means their are either incompatible or will work only
|
||
|
|
under specific settings. This is a list of such sensors and known workarounds
|
||
|
|
if they exist.
|
||
|
|
|
||
|
|
#### Grove Sensors
|
||
|
|
|
||
|
|
* **Grove I2C Touch Sensor** v1.3 is incompatible with the Intel Edison using
|
||
|
|
the Arduino board, but will work with the Mini-breakout if supplied with at
|
||
|
|
least 4V. Revision v1.2 works well on all Intel boards.
|
||
|
|
* **Grove Nunchuck** only works with the Intel Galileo boards and is unusable
|
||
|
|
on the Intel Edison boards.
|
||
|
|
* **Grove 3-Axis Digital Gyroscope** (ITG-3200) is not compatible with the
|
||
|
|
Intel Edison Arduino board but will work with the Mini-breakout.
|
||
|
|
* **Grove 3-Axis Digital Accelerometer** (ADXL345) only works with the Intel
|
||
|
|
Edison Arduino board when powered from the 3.3V line.
|
||
|
|
* **Grove 96x96 OLED Display** will not work on the Intel Edison with Arduino
|
||
|
|
breakout.
|
||
|
|
* **Grove 128x64 OLED Display** will not work on the Intel Edison with Arduino
|
||
|
|
breakout.
|
||
|
|
* **Grove Barometer** (BMP085) has an unstable connection on the Intel Edison
|
||
|
|
using the Arduino breakout and does not run properly.
|
||
|
|
* **Grove 6-Axis Accelerometer & Compass** (LSM303) fails to write to the
|
||
|
|
configuration register properly and returns invalid data.
|
||
|
|
* **Grove I2C ADC Converter** does not show up on the I2C bus on the Intel
|
||
|
|
Edison with the Arduino board.
|
||
|
|
* **Grove I2C Motor Driver** is not compatible with the Intel Galileo due to
|
||
|
|
the inability to change the I2C bus speed to 100 KHz.
|
||
|
|
* **Grove CO2 Sensor** will return zeroed data and is unusable on the Intel
|
||
|
|
Galileo.
|
||
|
|
* **Grove BLE** (HM-11) does not return data on the Intel Galileo board.
|
||
|
|
|
||
|
|
#### Adafruit Sensors
|
||
|
|
|
||
|
|
* **Adafruit Motor Shield** (1438) will not get detected on the I2C bus when
|
||
|
|
connected to the Intel Edison with an Arduino breakout.
|
||
|
|
|
||
|
|
#### Other Sensors
|
||
|
|
|
||
|
|
* **MPU9150** might return inaccurate data.
|
||
|
|
|
||
|
|
Some I2C sensors seem to add too much capacitance to the SDA line of the Intel
|
||
|
|
Edison Arduino breakout board, thus the signal essentially becomes stuck to a
|
||
|
|
logic 1. When this happens, any other sensors connected to the I2C bus will be
|
||
|
|
rendered useless too. There is no universal solution for this issue, but under
|
||
|
|
most cases the same sensor will work just fine on the Intel Edison Mini. Using
|
||
|
|
the same sensor but from a different vendor can also work in some cases.
