Be able to download and install the prerequisite board package needed to program the ATTiny85.Understand the basic concept of what the CS, MOSI, MISO and SCK signals are used for in the ISP protocol.Understand the basic steps involved in uploading a program to a slave AVR device using the ISP protocol.There are newer products out there but you can pick up a Dragon for < $50 on Ebay.
#Attiny85 port programming with atmel studio code#
Using a feature built-in to most AVRs, named "debugWire, " you can set breakpoints in the code and inspect the ATTiny's registers, variables and step through the code as it runs. It can be a finicky beast, but once you tame your Dragon, you'll wonder how you ever lived without it. I'm an old-school Visual Studio developer and the environment is very familiar to me, and living without intellisense and auto-complete is not an option! The programmer/debugger I use is an AVR Dragon. 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.
