Microcontroller programmable in C

Posted by Francesco M.P. Vitale on October 24, 2008, 11:21 am

Hi guys, my name's Francesco.
First of all... sorry for my english, it's not my native language.
I've never written on this forum, I hope it's the right one.

I'm working on a project at home during spare time.
The project involves the movement of 2 steppers (through 2 h-bridges)
depending on a specific logic.
At the moment I've been using an Arduino Diecimila. It has a proper I/
O pins number, but only 14kb
of usable memory for storing the program... It has been fine till the
memory ran out.

I'd like to know if some of you can suggest me another
microcontroller,
programmable using the C or C++ language, quite economic, with at
least 32 kb for storing
programs and with at least 16 pins for I/O. (Let me be more clear...
an Arduino with 32kb for storing the program would have been fine...
but it does't exist)

Thank you very much!!!
Francesco Vitale

You are doing fine. :-)

Been there and done that. ;-)

I used to do allot of PIC programming, but I wanted something faster that I
could program in C. I started playing with NXP ARM7 boards last year and I
really like the architecture; JTAG debugging is really convenient too.
www.olimex.com is a good place to look at some dev boards. Take a look at
this: http://www.olimex.com/dev/lpc-h2103.html It costs about 23 Euros.

Both of these sites have a pretty good selection of moderate cost
boards. Netburner stuff tends to be more network centric (as you might
expect) and Newmicros has a nice collection of boards from some pretty
simple 8 bit processors up to some pretty seriouse 32 bit processors.

I am kind of partial to the Freescale processors, I have worked with the
ARM architectures through the years and don't care for them much.

Good Luck!

According to the Arduino website they use the ATmega which is an Atmel AVR.
http://arduino.cc/en/Main/Hardware

You may find an answer on AVR Freaks
http://www.avrfreaks.net/
I'm thinking maybe there is a user project to add memory?

Sorry I can't be of more help.

adafruit has Arduino-bootloader 2x upgrade chip (Atmega328) listed as
in-stock.

A preprogrammed Atmega328 chip: More than TWICE the flash memory for
your sketches (30K available instead of 14K), TWICE the RAM (2K
instead of 1K)...
