Hi, I have got the same problem too. When I run the grove_ultrasonic.py It keeps caught by the TypeError.
Anyone have got the solution. Thanks!

What I am using:

  • Raspberry Pi 3 Model B+
  • GrovePi+

Hi @CRAZZZZZY,

Can you run grovepi.version()? What do you get by running this?

And just so you know, we are preparing to release a new version for the GrovePi’s firmware that only targets bug-fixes. We might give anyone who runs into problems a chance to test the new firmware and see if it works better than the previous.

Thank you!

I have enabled the debug mode, but keeps receiving the following errors:

Hi @CRAZZZZZY,

I’m pretty sure the GrovePi has no firmware flashed onto it.

Just to be sure about this, type in the command line i2cdetect -y 1 and see if there’s a device at 0x04 address.

Either way, try flashing it and see if it then works.

By the way, you can also use ``` (backticks) to enclose the code so that you can format it properly. Check your response because I have edited yours.

Thank you!

Thanks Robert,

I have ran the i2cdetect -y 1 and got the following result

 0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Also, I have tried executing firmware_update.sh. However, it encountered the following message:

avrdude: Can’t find programmer id “gpio”

Isn’t that I have missed something? Thanks.

Hi @CRAZZZZZY,

Either you have tried to install the GrovePi manually, or you’re using a very old version of Raspbian For Robots.

I would run the following command if I were you:

curl -kL dexterindustries.com/update_grovepi | bash

Once you do that, try flashing the firmware again.

Let me know how this goes for you.

Thank you!
