Next you will need to connect up the pins that do the programming. GPIO 8 is the second to bottom most pin on the right of the Pi GPIO header.

Colour Code It’s a good idea to stick with red/black wire for power/ground and pick separate colours for serial and SPI.įirst connect GPIO 8 on your Raspberry Pi to the Reset pin on the Trinket. If you’re doing this on a breadboard you’ll need 6 female-to-male jump leads power, ground, mosi, miso, clock, reset. Once you’ve got the Trinket set up on your breadboard you need to make the power and SPI connections to it from your Raspberry Pi GPIO header. Align it so that the USB port hangs over one edge, although we won’t be programming the Trinket over USB it’s a handy source of power. You should then pop the Trinket into the 170pt breadboard. This will let you push it into a breadboard and keep it securely positioned for tinkering. Connecting Them Togetherįirst, solder two 4-pin male headers to your Trinket pointing downwards.

This should install the Arduino IDE, the modified avrdude ( used for flashing programs to your Trinket ) and Arduino-Makefile which makes it easier to compile your Arduino programs from the command-line and avoid the Arduino IDE itself.Īlternatively you can manually install each component from the GitHub repo, and I'll assume you know what you're doing!. We’ve put together a simple setup script which will get you set up in a jiffy, just: git clone If you’re running Raspbian you can just grab the contents of our GitHub repository. You’ve got two choices when it comes to setting up the software. We recommend our Jumper Jerky to make all the necessary connections. If you have male to male wires and an extra breadboard handy you can use the Adafruit Pi T-Cobbler to clarify where the SPI, power and Serial pins are.

The 3 remaining pins are reserved for power, ground and reset. Two of these can be configured as analog inputs and two as PWM outputs.

The skills you pick up from tinkering with a Trinket and learning how to program it will also be transferable should you decide to try any Arduino products. One that you can not only use with your Pi, but as a stand-alone controller. The trinket is a cheap and flexible alternative to a PWM driver, or an analog to digital converter. Generate precisely timed signals, like the one needed for WS2812 LEDs.Read cheap analog sensors, such as temperature or light intensity.Generate PWM ( Pulse-width-modulation ) signals, for Servos/Variable LED brightness.The Trinket can do many things that your Pi either can't do, or isn't great at: The Trinket and the Pi are a very complementary pair. Warning: Make sure you use the 3.3v Trinket, don't connect a 5v one directly to your Pi! Why Combine A Trinket And A Pi? Programming the Adafruit Trinket from your Raspberry Pi
