How to connect to raspberry pi

Post by Luisacgarcia5 »

I'm new to Adafruit and I wanted to know if there's a way to connect the Joy FeatherWing to a Raspberry Pi 4 without using the Feather board. I tried connecting the SDA and SCL pins, as well as the 3.3V pin on the Raspberry Pi, but when I tried to run the code from the example Adafruit library, the Raspberry Pi didn't detect anything. Please help!

First off,what example code are you running, did the pi see any i2c connection and have you tried scanning for i2c?

Yes, enable I2C and install the i2c-tools, then scan the I2C bus. However, I noticed that my Joy FeatherWing is not on since the LED light is not flashing. Do I need the Feather board to power it, or can I use the Raspberry Pi 3 to power it? I'm following the example in https://github.com/adafruit/Adafruit_Ci ... herwing.py

The FeatherWing will need power.

I am delivering power to the featherwing as the diagram recommended, but it's not turning on
