Grove_led_blink.pu

Hello Folks,

I have a GrovePi+ with Raspberry Pi 2 and a Grove LED.

After installing firmware the GrovePi+ is detected, however I cannot get the LED to flash. I tried 2 different Grove LED microcontrollers and reversed LEDs on both.

I ran all_tests.sh… results are attached.

Any help would be very much appreciated.

I’ve compared your test to mine, and what seems suspicious to me is your grovePi firmware version.
Also you don’t have spidev in your /dev folder, but that might be because I play with tons of stuff with my pi.

Are you running the latest Dexter Robots for Raspbian?
