I’m thinking that your
GrovePi isn’t (properly) flashed.
For the moment I’m not going to ask for any logs.
So, lets do the following.
Also, I assume you’re using a
Raspbian For Robots image.
If not, please follow these instructions:
Raspbian for Robots image from here.
For burning your
micro SD Card, follow this tutorial.
sudo i2cdetect -y 1 shows anything.
Otherwise, continue reading this post.
Open up a terminal and enter the following commands:
sudo bash firmware_update.sh
Then, check again with
sudo i2cdetect -y 1 to see if address
0x04 shows up.
For now, that’s all we’re going to do.
I’m waiting to see how things evolve.
