Atmel Studio 7 coupled with a programmer/debugger - I mention Atmel Studio, because that's the IDE I normally use.A multi-meter that can measure voltage and amperage in the milli and micro range will be very useful. It's very important to conserve power when we can. Most ATTiny projects will probably be small and be run from a coin cell battery. Multi-meter - Power will be a major discussion point.Oscilloscope - I'll include images of my oscilloscope for reference, but an oscilloscope in invaluable when experimenting with different PWM signals and monitoring other input and output signals.Some things that would be extremely helpful, but not mandatory for this series:

For example, with a few jumper wire changes, the setup we'll discuss below will program an ATTiny84 (the ATTiny85's bigger cousin) to give you access to more functionality, as well as more input/output pins. Once you've mastered the ATTiny85, you'll feel comfortable programming just about any AVR MCU product on the market, including the ATMega328 that's at the heart of the Arduino Uno. I will be referring to it frequently throughout this series.

If you're really serious about a deep dive into the ATTiny85, the very first thing you should do is download the ATTiny 25/45/85 datasheet from Microchip.

Analog to Digital Converter (ADC) Control Registers.

Some of the registers we'll examine (in exhaustive detail) in future lessons of this series: Instead, we'll be accessing the control registers built-in to the ATTiny (and every other AVR) to control the behavior of the MCU and peripherals. The reason we won't be using these easy-to-use methods will become more apparent as you make your way through this series.

and delay(), we'll never, ever use delay.

However, we will not be using the methods you may be familiar with to program the ATTiny, these include things like: No prior experience is necessary and we'll use the familiar Arduino IDE for all lessons in this series.

Hold ”Shift” on keyboard and press “Verify”, Arduino IDE will show the target file’s location.This series focuses on the ATTiny85 AVR. PS: I will try it with a real Arduino and atmega48 in a few days. It dose work! I loaded the hex file to a virtual atmega48 and it really blinks! The temp folder can be entered in this way.Īnd the file we need is located in a build folder. It must be copied before you exit the Arduino IDE because the exiting process will empty the build folder. A hex file will be generated in temp folder. Then choose the new board and compile the sketch by press the “Verify” button. Besides, my Dragon programmer is not supported by Arduino so any programmer besides the bootloader will do. The bootloader doesn’t bother in a chip with large flash but it really matters to a chip with only 4K flash.

So modifications in the sketches are NOT needed.įirst I added the Atmega48’s information to boards.txt The pinouts and the registers are totally the same. In this time I use Atmega48 because the only difference between the original Atmega328 and the Atmega48 is the flash and sram. So some modification can be made to enable Arduino to support cheaper chips. But one problem is, we do not need a large Rom in all case especially to the programs written by C. Since it uses AVR-GCC compiler, standard C is also acceptable to maximize its performance. It is extremely easy to handle and do quick prototyping.
