Using ATMega32 instead of ATMega328 chip

Former Member
Former Member over 13 years ago

We are doing a project on getting the temperature and humidity details from sensors, displaying it on LCD, and sending it wirelessly using Xbee to another Arduino module to get processed and displayed. For the first part we have written the program in C for the chip ATMega32 not for ATMega328, and simulated in Proteus. Can you tell me whether there is an Arduino kit for this particular IC ATmega32? We have written the code for the second part (Processing and displaying it, may be we will include sending the data using GSM) also in C. For this part we wish to use ATMega328 and Arduino kit. But can we burn this C program into the IC using Aurduino Uno kit? What is the difference between the programming in Arduino kit and C program?

We are beginners and it would be really helpful if you can clear our queries.

    There is a board called Sanguino (www.saguino.cc) which uses the ATMega644p. This chip has 64K flash and IIRC the same pinout as an ATMega32.

    Check out their site, there's a comparison between the Arduino and the Sanguino and also (under 'useit') software and how to install it in the Arduino IDE (boards.txt)

    Hi Veeresh,

    Can you tell me whether there is an Arduino kit for this particular IC ATmega32?

    This is an ATMega32-based Arduino clone and the download on this page may interest you:

     

    http://www.thaieasyelec.net/index.php/Arduino/ATmega32-Dev-Board-Arduino-Diecimila-Compatible-DIP-28-DIP-40-/p_133.html

     

    But can we burn this C program into the IC using Aurduino Uno kit? What is the difference between the programming in Arduino kit and C program?

    The Uno has an ATMega328.  Normally, it comes programmed with Arduino bootloader which allows the Arduino IDE to load your sketches over USB.  You can replace the bootloader with your own C program complied for the ATMega328.  This is done via ISP (In System Programming).  If you have an extra Arduino, then you can use the other Arduino as an ISP programmer:

    Or you can use a dedicated ISP programmer.  I use Adafruit's USB TinyISP and love it:

    Cheers,

    Drew

    Oh, I guess I didn't answer your third question, the main difference I'd say between programming in C versus using the Arduino platform is that the Arduino libraries make most things much easier.  If you haven't seen them, check out Jeremy Blum's Arduino programming tutorials: http://www.element14.com/community/groups/arduino?view=video
