Hardware I2C / SPI capability for breakout & sensor interfacing.

The 2 shared IO pins have 2 more analog inputs and one more PWM output. The 3 independent IO pins have 1 analog input and 2 PWM output as well.

5 GPIO - 2 shared with the USB interface.

No need to unplug/replug the board every time you want to reset or update!

Reset button for entering the bootloader or restarting the program.

On-board green power LED and red pin #1 LED.

Power with either USB or external output (such as a battery) - it'll automatically switch over.

Adafruit trinket 5v clock tutorial pro#

There are two versions of the Pro Trinket: 3V and 5V. Also known as the SPI CLOCK pin Analog 0 also known as Digital 14, this pin can be a digital I/O pin or an analog input pin. Arduino Tutorial - Adafruit Pro Trinket Board - with Codebender. Up to 16V input, reverse-polarity protection, thermal and current-limit protection. Arduino Tutorial - Adafruit Pro Trinket Board - with Codebender.

On-board 5.0V power regulator with 150mA output capability and ultra-low dropout.~5.25K bytes available for use (2.75K taken for the bootloader).The bootloader is rugged and foolproof: this board wont up and die on you in the middle of a project!.Mini-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.USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude (with a simple config modification) and/or the Arduino IDE (with a few simple config modifications).

Adafruit trinket 5v clock tutorial software#

Internal oscillator runs at 8MHz, but can be doubled in software for 16MHz.

ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.

Simply use a USB v2 port or a USB hub in between.

Some computers' USB v3 ports don't recognize the Trinket's bootloader.

Adafruit trinket 5v clock tutorial serial#

Trinket does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data.There are some things you trade off for such a small and low cost microcontroller! Version 2.0 Use with Arduino IDE Version 1.6.5 or later and Adafruit libraries modified December 2015 or later.

Adafruit trinket 5v clock tutorial code#

It can run at 8 MHz or at 16MHz by setting the software-set clock frequency.Įven though you can program Trinket using the Arduino IDE, it's not a fully 100% Arduino-compatible. Trinket RGB LCD Shield Clock Example code for the Adafruit RGB Character LCD Shield and Library for Trinket The DS1307 Real Time Clock must be initialized with a separate sketch. You can't stack a big shield on it but for many small & simple projects the Trinket will be your go-to platform. After some simple modifications to the Arduino IDE, it works like a mini-Arduino board. Uses a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. It's our lowest-cost arduino-IDE programmable board! Perfect for when you don't want to give up your expensive dev-board and you aren't willing to take apart the project you worked so hard to design. It's a microcontroller board that is small enough to fit into any project, and low cost enough to use without hesitation. Soldering a wire works best.Trinket may be small, but do not be fooled by its size! It's a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. Alternatively, sometimes you can just hold the reset button down while running the sketch (type 'G' to start) and it might work. You may have to solder a wire temporarily. the Reset pin is underneath the MiniUSB Jack.

Trinket VBAT+ pin to Arduino 5V (or just power it via a battery or USB cable).

For example, running the Arduino at 5V and reducing the clock speed from. This loader isn't tested to work with any other kind of Arduino. In this guide well see if we can reduce the supply current to less than 10uA. You can use an Arduino UNO to re-program the bootloader onto your Trinket (or Gemma). This means its possible to accidentally overwrite the bootloader (or even if you unplug the Trinket while uploading it might have difficulties from then on) The ATtiny85 does not have a protected-bootloader section.
