As far as IDE is concerned, I used to use Code vision and AVR Studio but I recommend using Atmel Studio 6.0 or newer which caters to all your needs.ATMega16 and ATMega128 have ISP and JTAG interface. If you are using a 5V supply I recommend you ATMega8 or even ATMega16 or ATMega128 (my fav).

But if you are looking not only to blink a few LEDs but want to interface with say an LCD screen or a keypad or what have you then I recommend to go in for a slightly bigger microcontroller. Small microcontrollers such as AT90S2313 or ATTINY series use ISP series as these are small in size.

You will find that most Atmel microcontrollers have ISP functionality but not many have JTAG.

JTAGICE is a bit costlier than AVR Dragon but I definitely recommend AVR Dragon. Both connect to PC via USB and both provide ISP and JTAG. I think you buy once but buy good which will help you in future if you wish to change your design.

Buy a debugger which has both ISP and JTAG functionality.

And there is Debug Wire interface which I would like to skip in this discussion because you rather use ISP than debug wire. People usually lean more towards ISP because its 'relatively' easier to setup but if you ask me JTAG is not difficult to setup, but it also comes down to personal preference.

JTAG interface uses 4 pins which provides you with basically full functionality in terms of using breakpoints and stuff.

ISP (In-Circuit Programming) is a serial interface, uses 3 pins which is good but does not provide full functionality a beginner would want. Debuggers provide you with the ability to program the microcontroller as well as debug which includes 'step by step' processing, 'breakpoints' which allows you to pause the program at a certain line of code to check what the code is up to. I see people have posted some useful answers but I have been where you are and I would do things a wee bit different.

To move from Arduino where the hardware is provided and the software is a C language overlay, I would like to make a few suggestions. I've found that poring over register descriptions kinda sucks no sense in doing that if you don't have to. Explore the various peripherals and their registers and soon it'll be totally natural.Īfter all of this, I often find myself using Arduino because it's faster. Once you've attained blinky with the command line tools only, you're free from Arduino. After some more trial and error, I managed to program the ATTiny with avrdude only, staying completely outside the Arudino ecosystem. Then, I installed the free Crosspack command line toolchain and compiled a blinky program. I used the Arduino IDE to compile but kept using registers as much as I could. If you buy a breadboard power supply and use the ATTiny's internal oscillator, this requires laughably little wiring. My next step was to put an ATTiny 85 on a breadboard and program it with Arduino as ISP ( ). Arduino functions like digitalWrite() simply manipulate the registers - you are free to read and write to them directly in your sketches.

This way I got used to using registers and saw that they were not radically discontinuous with the Arduino way of doing things. To start, I kept using an Arduino but converted calls to the Arduino library into register reads and writes, one line at a time, seeing if my programs still worked. You don't have to "graduate" all at once. Second, other than the power supply, is there anything on the Arduino that I absolutely need? I guess maybe a reset switch? Then I guess I (properly) wire the connector to certain pins on the ATmega. From the bit of reading I've done, I think I need a programming cable, and a connector on my board (what type?). Of course changing the software would be inconvenient.īut for option #2, I'm not sure what I need. I'm assuming that if I go with option #1, it's as simple as inserting a programmed chip in my circuit I don't need anything else. Design my circuit to include support for in-circuit programming.Buy a programmer, program the MCU, and then place the chip in my circuit.

My first question is how to program the MCU. I understand that development tools are available free or at least not very expensive.įor the purpose of this question, assume I can get +5V to my circuit. Unless there is a better option, I'm leaning towards using the ATmega328, which is used by the Arduino. I know there are methods to make my own Arduino on a breadboard, but that's not really what I'm trying to do. This will allow a single board, no shield solution. That is, I would like to use a microcontroller without involving the Arduino board. After I get everything working using the Arduino, I would like to move to a solution that does NOT use Arduino.
