BOTTOM The counter reaches the BOTTOM when it becomes 0x0000. MAX The counter reaches its MAXimum when it becomes 0xFFFF (decimal 65535). TOP The counter reaches the TOP when it becomes equal to the highest value in the count sequence. The TOP value can be assigned to be one of the fixed values: 0x00FF, 0x01FF, or 0x03FF, or to the value stored in the OCR1A or ICR1 Register. The assignment is dependent of the mode of operation.

Overview Trinket's got a big sister in town - the Pro Trinket! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in. © Adafruit Industries https://learn.adafruit.
PAGE 560
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. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. © Adafruit Industries https://learn.adafruit.
PAGE 561
Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. 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. © Adafruit Industries https://learn.adafruit.
PAGE 562
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. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. © Adafruit Industries https://learn.adafruit.
PAGE 563
The Pro Trinket 5V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. at the same speed and voltage.
PAGE 564
Here's some handy specifications: ATmega328P onboad chip in QFN package 16MHz clock rate, 28K FLASH available USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications). Also has headers for an FTDI port for reprogramming Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram. On-board 5.
PAGE 566
Guided Tour Let me take you on a tour of your Trinket! Each trinket is assembled here at Adafruit and comes chock-full of good design to make it a joy to use. Micro -B USB co nnecto r - We went with the ultra-common micro-B USB connector for power and/or USB bootloading. We use a special half SMT/half thru hole connector with extra big pads so the connector is very strong. It's also a proper USB connector, so you can use any length cable.
PAGE 567
higher voltage USB Po wer Output - You can also snag the 5V power from the USB jack in case you need 500mA+ current from your computer or portable USB power pack. Breadbo ard friendly pins - You can easily plug this into a little breadboard and have plenty of space for working and plugging stuff in GPIO pins - 18 GPIO pins + 2 analog-only pins, at 3 or 5V logic, check the next section for a detailed pinout guide 3 o r 5V o utput - an onboard regulator provides 3.
PAGE 568
Pinouts There are two versions of the Pro Trinket: 3V and 5V. They are almost identical but there are slight differences in the pinouts: one has a 3V output pin in the top right, the other has a 5V output pin instead Power Pins We'll start with the top pins BAT+, USB+, 3V/5V, and GND BAT+ is the Battery + Input pin. If you want to power the Pro 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.
PAGE 569
something, like charging a battery, or if you need more than 150mA of current (this pin can supply 500mA+ from USB ports) or to detect when the Pro Trinket is plugged into USB, this pin will have 5V power on it if and only if its plugged into something via the mini B connector GND is the common ground pin, used for logic and power. It is connected to the USB ground and the power regulator, etc.
PAGE 570
The Digital Only GPIO Pins RX - also known as Digital #0, this is the hardware serial input pin TX - also known as Digital #1, this is the hardware serial output pin Digital 3 - this pin can also be used as a PWM output pin using analo gWrite() Digital 4 - Nothing particularly special about this GPIO pin Digital 5 - this pin can also be used as a PWM output pin using analo gWrite() Digital 6 - this pin can also be used as a PWM output pin using analo gWrite() Digital 8 - Nothing particularly special about t
PAGE 571
The Analog/Digital GPIO Pins Analo g 0 - also known as Digital input pin Analo g 1 - also known as Digital input pin Analo g 2 - also known as Digital input pin Analo g 3 - also known as Digital input pin Analo g 4 - also known as Digital input pin. It's also the I2C SDA pin Analo g 5 - also known as Digital input pin.
PAGE 572
The Analog only pins The two pins that sit sort-of inside the body of the Pro Trinket, A6 and A7, are analog input only pins. They're kind of an 'extra' that you get with the Pro Trinket. These pins canno t be used for LEDs, buttons, servos, etc. They're only for analo gRead() usage! If you're used to using an Arduino Uno, you may notice that pins #2 and #7 are not available. That's because we use those two pins for the USB bootloader. They are not available for use and are not broken out.
PAGE 573
Other Pins Aref - this is the optional analog reference pin for the analog converter, to be used when you want the 'top' of the analog converter to be different than 3V or 5V. Connect this to your desired reference voltage (between 0 and the Pro Trinket voltage) and use analo gReference(EXTERNAL) RST - This is the Reset pin for the Pro Trinket. Connecting this to ground momentarily resets the Trinket and also starts up the bootloader. © Adafruit Industries https://learn.adafruit.
PAGE 574
FTDI Breakout At the bottom is 6 pins in a row that we call the FTDI header. You can use these pins to program the Pro Trinket with an FTDI cable or FTDI Friend. You can also use it for serial debugging. GND - same as the power ground pins 5V - same as the VBUS pin RX - same as the RX pin TX - same as the TX pin RST - there's a 0.
PAGE 576
Using the USB Bootloader About the bootloader A bootloader is a tiny piece of software residing on the microcontroller that that helps load your own code into the remaining space. One of the challenges with the Pro Trinket is that we wanted to have a built-in USB bootloader, but the ATmega328 doesn't have built-in USB hardware! So instead, Frank (our awesome engineer with mad USB chops) (http://adafru.
PAGE 577
Download Pro Trinket Drivers for Windows http://adafru.it/djr Don't forget to plug in the Pro Trinket via a known-good USB cable to start the process. You should see the green power LED lit and the red bootloading LED pulse indicating that the Trinket is ready to start bootloading.
PAGE 578
connect to the USBtiny driver. That way you don't have to be root all the time! Check http://learn.adafruit.com/usbtinyisp/avrdude#for-linux (http://adafru.it/cf3) for what to add to your udev file. How to start the USB bootloader Before you try to upload code to the Pro Trinket using the USB bootloader it must be in the Bootloader Mode. That means its listening for a sketch or program to be sent to it When the Pro Trinket is in bootloader mode, the red LED will be pulsing.
PAGE 580
For beginners, we suggest using an FTDI cable for programming and debugging, especially if you aren't simply porting an existing Arduino project to Pro Trinket. Much like many Arduinocompatibles, there's a header for connecting a 'classic' FTDI cable (http://adafru.it/dNN) or FTDI friend. (http://adafru.it/dQa) © Adafruit Industries https://learn.adafruit.
PAGE 581
The bootloader on Pro Trinket is dual USB & FTDI "optiboot" so you can use either the USB port or the FTDI breakout to upload. However, only the FTDI port allows you to use Serial debugging. So it's a bit of a tradeoff - USB is inexpensive, built-in but requires a button press to start & there's no debugging, FTDI requires an extra cable but has auto-reset and debug console.
PAGE 582
Connect FTDI Friend or Cable You'll need to solder 6-pin header onto the FTDI breakout first. Match the black wire and green wire with the BLK and GRN markings on the PCB next to the FTDI header © Adafruit Industries https://learn.adafruit.
PAGE 583
Don't forget you'll need to install FTDI VCP drivers, available from FTDI chip. (http://adafru.it/aJv) Then select the COM port from the Tools menu as well, to upload! © Adafruit Industries https://learn.adafruit.
PAGE 584
Setting up Arduino IDE Chances are, you picked up a Trinket because it is programmable with the Arduino IDE.
PAGE 585
Linux (64-bit) http://adafru.it/dXb Be sure to extract the contents of the zip file. The IDE will not execute properly from a compressed folder. Mac OSX If you're using Mac OS Mavericks you will need to update the setting to permit running Arduino IDE 1. 2. 3. 4. 5. 6. Open System Preferences and select the Security and Privacy icon. Select the 'General' tab Click the Lock Icon and Login Change "Allow Apps Downloaded From": to "Anywhere" Open the downloaded IDE.

minutes and you only have to do it once! This tutorial will base the IDE off of v1.0.5 which is current at time of writing. You can try later versions but v1.0.5 is at least guaranteed to work Adding Pro Trinket support does not affect any other boards that are affected so you can continue to use the IDE with any Arduino board currently supported.
PAGE 587
OK you are done! (Not so bad, eh?) Blink! OK let's practice uploading a sketch by uploading the classic Blink sketch with the USB bootloader. This program with blink the onboard red LED that is connected to pin #13.
PAGE 588
Plug in the Trinket, make sure you see the green LED lit (power good) and the red LED pulsing. Press the button if the red LED is not pulsing, to get into bootloader mode. Click the Uplo ad button (or select File->Uplo ad) If everything goes smoothly you should see the following (no red error messages) and of course, the red LED on the trinket will blink on/off once a second © Adafruit Industries https://learn.adafruit.
PAGE 589
Something Went Wrong! If you get the error message avrdude: Error: Could not find USBtiny device (0x1781/0xc9f) That means the bootloader wasn't active. Make sure to press the button on the Trinket to activate the bootloader before clicking the Upload button. Also, check that you see the red pulsing LED on #13 that indicates the USB bootloader enumerated to your computer © Adafruit Industries https://learn.adafruit.

Also, don't forget to install the Windows driver if you're using windows! © Adafruit Industries https://learn.adafruit.
PAGE 591
Hints for Arduino-compatibility The Pro Trinket uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. It's the 'classic' Arduino chip! So you'll be happy to hear that not only is Pro Trinket programmable using the Arduino IDE as you already set up, but 99% of Arduino projects will work out of the box! The Pro Trinket 5V runs at 16MHz, just like the Uno.
PAGE 592
The 3V Pro Trinket runs at 12MHz not 16MHz so its a bit slower. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes. The bootloader does not affect RAM usage. © Adafruit Industries https://learn.adafruit.
