If you have a 5V trinket, 5.5V or higher is. If you have a 3V Trinket, you'll want at least 3.5V input to get a good 3.3V output.

(If not, you are probably going to have to reboot your computer to reset the serial driver)ДЄnd to avoid the problem, avoid rebooting your arduino over serial WHILE it is already in the process of rebooting. If you want to power the trinket from a battery or power adapter or solar panel or any other kind of power source, connect the + (positive) pin here You can connect up to 16V DC. (may need to select something very different, mine is a /dev/cu, so I select a /dev/ty) and try to upload. Each trinket is assembled here at Adafruit and comes chock-full of good design to make it a joy to use. Your serial interface will not be listed, nothing will be checked. Hm, it looks like it still cant find the programmer itself. Open your serial select and note which one is checked.

I was just rebooting my computer, and that always worked, but I've found a faster way.

Sometimes it just plain gets STUBBORN and you have to get more drastic. According to the Adafruit page on the Trinket Pro, the Trinket Pro 'bootloader looks just like a USBtinyISP' therefore, you would talk to it in the same way as the USB Tiny ISP that your system reports finding, ie, without using a /dev/ttyXXX device, but rather by specifying -c usbtiny in the avrdude command line, or using an Arduino IDE board configuration which does so. Sometimes quitting the IDE and relaunching fixes it.

If these reboots happen too close to each other, (turn on the serial monitor within 1 sec of the upload finishing because you are impatient) it often causes the serial port driver to jam up and you get this message when you try to upload. But when you turn on the serial monitor, it reboots it AGAIN. (which always turns off and closes when you upload?) When the upload finishes, it reboots the ardweeny. After I hit upload, I tend to turn on the serial monitor.

Overview AVR programmer & SPI interface Introduction This is documentation for a simple open-source USB AVR programmer and SPI interface. To upload to your or Trinket: 1) Select the proper board from the Tools->Board Menu (Arduino Gemma if teal, Adafruit Gemma if black) 2) Select the uploader from the Tools->Programmer ('Arduino Gemma' if teal, 'USBtinyISP' if black Gemma) 3) Plug in the Gemma into USB, make sure you see the green LED. Im running avrdude and I get avrdude: Cant find programmer id 'usbtiny' В©Adafruit Industries of 94 В©Adafruit Industries of 94.

I use ardweenys a LOT here for their low cost, and I find this problem somewhat frequently when I'm in a hurry. This example code is in the public domain. Serial.Sometimes you have to do some more zigzagging to get it to work again. initialize digital pin LED_BUILTIN as an output.

The driver does not implement suspend handling by itself. Bus-powered devices can achieve this only by putting the: CPU in sleep mode.

Parameter 3 = pixel type flags, add together as needed: This is not a problem for self-powered devices since they dont need: bus power anyway.

Parameter 2 = pin number (most are valid) Parameter 1 = number of pixels in strip
