Arduino shrunk how to use ATtiny. Arduino IDELots of different MCUs can be worked on using the Arduino IDE, not just the Arduino boardsArduino IDE Integrated Development Environment, currently in version 1. Arduino boards. It has an easy to learn intuitive interface and comes with all the necessary settings for the most common Arduino boards Uno, Duemilanove, Nano and others based on ATmega. ATmega. 32. 8 microcontrollers. The latest version also includes some of the most recent ATmega. ATmega. 25. 60 boards. But you wouldnt be using all of its great capabilities if you had to switch back to a text editor every time you needed to program a smaller Atmel chip, such as ATtiny. The engines behind the Arduino IDE AVR GCC compiler for C and C and avrdude an in system programming software for Atmels AVR series of micros are already there and capable of coding for and programming the smaller chips, we just need to add a little bit of configuration magic to the Arduino IDE to be able to switch hardware freely without leaving your favorite Integrated Development Environment. Here is how Arduino IDE keeps the hardware specific C libraries and other necessary configuration files in a directory called hardware which can be either under the IDEs root directory from this point on Ill call it arduinohome for brevity or the users sketchbook directory. I am using a Ubuntu linux machine and my sketchbook directory is sketchbook. It can be a different location on a Windows PC please check the manual for Win version. The hardware specific libraries are called cores and they are located under sketchbookhardwarexxxxcores where xxxx can be either arduino or a hardware name that the developer of the libraries settled on tiny, for example. It can also be under arduinohomehardwarearduinocores Another file crucial for IDEs understanding of what hardware youre working on is a file called boards. The file contains information about the hardware the board can be a stand alone MCU, too, such as the clock speed of the processor, high and low fuse bytes the configuration settings that get burned into the microprocessor and define the clock source, timer prescaler and other important settings that dont need to be updated every time you re upload your sketch. MCU an important issue for MCUs such as ATtiny that can be slowed down greatly by using an internal clock source. So far I came across three different sets of libraries suitable for programming of ATtiny microcontrollers Most of them contain versions of several basic Arduino functions that can run on MCUs with such small Flash and SRAM sizes as the ATtiny. Most often supported functions include millismicros not really a true microseconddelaydelay.

Writepin. Modedigital. Readdigital. WriteKeep this set of functions in mind when writing your software more complex functions such as math and trigonometry functions may work but will probably exhaust resources of the little MCU too quickly. Rundll.Exe Download Xp. All ATTiny cores install in a similar way Shut down the Arduino IDEIdentify the sketchbook directory on Linux look for sketchbook and create a new directory called hardware sketchbookhardware. If the core is zipped with the directory structure, simply unzip the content of the zip file into the sketchbookhardware directory it will create the subdirectory needed. Else, manually create a subdirectory called something like tiny or core. The name of the directory can be rather arbitrary, as long as it is the same as set up in boards. Inside the sketchbookhardwaretiny directory, edit or create a new file called boards. The boards. txt file for ATTiny should contain this data core. Attiny. 13 1. 28 KHz internal watchdog oscillator.

The DS1302 is a Real Time Clock RTC or TimeKeeping Chip with a buildin TrickleCharger. Important note Cheap modules with the DS1302 and. The InvenSense MPU6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, as it contains 16bits analog to digital. Once the configuration files are edited, start the IDE. In the Programmer section select the programmer you will be using see picture on the left. I am using the Atmel AVRISP mk II USB programmer but Arduino itself can also be used for ICSP programming of AVR MCUs. In the Tools Board menu select the MCU and the clock speed you will be using see picture at the top of the page. Before uploading any actual code, run Burn Bootloader a menu item right next to Programmer under Tools. There is no Arduino bootleader for ATtiny because of the small memory and IO size but the feature actually burns the low and high fuse bytes the configuration step needed for making sure the MCU runs at the speed that you assume it does.

SRAM and, obviously, only 5 x IOs if you are planning to load the code via ICSP the most convenient way to load the code. If you are going to use a different programming technique which Arduino IDE wont do, however, you can reuse the Reset pin as a 6th IO. Connect ATtiny. 13 to the programmer as shown on this diagram. At this point in time, you should connect your ATtiny. MCU to the programmers ICSP 6 pin header using the pinout in the picture on the left. If youre building your project on a breadboard, it is always handy to have 6 x 1. AWG colored wires soldered to a dual row 6 pin male header it will make the programmer connection easy and can be reused from project to project. V to 5. 5. V power should be applied to Vcc before programming the chip. Upload the complied program into your ATtiny. After you think you are done with the program, use the Upload Using Programmer Ctrl Shift U to compile the program and load it into the MCU. Remember that the power should be applied to the MCU before programming it Your program is now running Or not If it has bugs in it. If youre not getting the intended operation of the MCU, verify the program and upload it again steps 8 1. One of the things to keep track of while writing a code for ATtiny. RAM your program is using. For example, each declared variable gets a space in RAM, and you should always use the shortest possible variable type. For example, if you have a counter that does not go over 2. With only 6. 4 bytes of RAM every byte counts If youre declaring considerable size constants, such as arrays or text strings, consider using PROGMEM to move them from RAM to FLASH space, where you might have much more space to work with. Ive had great fun programming ATtiny. Arduino IDE. The IDE provides a very comfortable environment to work with and the limitations of the small MCUs like ATtiny. If you havent yet, I think you should definitely add the ATtiny to your projects.
