Unplug the Trinket and plug it back in. The red LED does not flash when I press the reset button and I always get the error message below when trying to upload.Īvrdude: Error: Could not find USBtiny device (0x1781/0xc9f) Problems I had and things I did to fix them: Problem: If the red LED turns solid, it is likely that your sketch uploaded even if you get an error. This means it is ready to receive the sketch.Ħ) WATCH the RED LED!! If your sketch is uploaded, it should turn solid briefly before going off.

(The sketch will start compiling)Ĥ) Press the button (don't hold it down!) on the Trinket toward the end of the sketch compiling, you want the red LED to be blinking when the code is trying to upload.ĥ) The red LED on the Trinket should pulse. To upload to the Trinket, these instructions are handy:ġ) Under Tools->Board Menu Adafruit Trinket 8MHz is selected.Ģ) Under Tools->Programmer USBtinyISP is selected.ģ) Press Ctrl+Shift+U to Upload code using the programmer.

Note: The Trinket doesn't have a USB Serial interface so you won't see a COM port for it.

Under Tools->Programmer select USBtinyISP.Under Tools->Board Menu select the Adafruit Trinket 8MHz.

For windows, make sure to install the USBtiny drivers.Updated the ATTiny85 section of your nf file.To get started, make sure you've done these things: Hopefully this will save some headaches for others who might also like to use the Trinket. You can find a lot of information on solving problems on the Adafruit website, but I find it takes a while to get to what your looking for. This has been trying at times so I thought I'd share my experiences here.

The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.The USB connection is for uploading new code only. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. There is no Serial-to-USB chip onboard.You cannot plug shields directly into the Pro Trinket.The onboard power supply is a 3.3V regulator and it can provide 150mA output.Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The Pro Trinket 3V runs at 12MHz, this doesn’t affect most projects.Pins #2 and #7 are not available (they are exclusively for USB).Here’s some things you may have to consider when adapting Arduino sketches: Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! However, it uses 3V logic and 12MHz clock which means it’s good when you want a lower-power and lower-voltage setup. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it’s great once you’ve finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5″ x 0.7″ x 0.2″ (without headers) but packs the same capability as an Arduino UNO. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. Like the Trinket, it has onboard USB bootloading support – we opted for a MicroUSB jack this time. That’s why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Trinket’s a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. It’s like an Arduino Pro Mini with more pins and USB tossed in. Trinket’s got a big sister in town – the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328.
