Adafruit feather M0 bluefruit le and the ble midi pin out Moderators: adafruit_support_bill, adafruit

Hi, I’m fairly new to the forum
I have a Adafruit feather m0 bluefruit le. I recently compiled a code for a Bluetooth drum machine prototype using the bleuntztrument library (I can post that if needed). I’m using a breadboard styled in the simple midi instrument provided on Adafruit page. It says on the blue fruit config file within the successful code compiling that the pins I’m suppose to use is 8,7,4. These pins I cannot find on the feather m0 but I read that these pins represent what is used for ble. I have the board show in my daw but it’s not triggering because I am unsure where I would find 8,7,4 pins. I apologize if I’m not explaining this correctly. I just need to find where I am to connect the PIN numbers when they don’t show on the board. Thank you and sorry

This is the library I’m using but I’m just using the feather m0 blue fruit le

Those pins are wired internally. They are not broken out.

There's a pin out diagram here:

and a schematic here:

4 = BLE RST (reset)
7 = BLE IRQ (interrupt)
8 = BLE CS (chip select)

If I wanted to use the feather m0 blue fruit with a breadboard with buttons to trigger the midi notes I wanted to get a better understanding on how to assign the buttons to the three blue fruit inputs you listed above.
