I need some help in choosing a MCU.
« on: March 30, 2009, 01:42:12 PM »
I am getting started on my next project and I want to have a MCU that will be able to control 10-14 servos 4 or more object avoidance sensors, a camera for blob tracking, LCD (serial), and maybe some other little components.

I want to make my own board, and I want to finally get started with using AVR's, C compiler reccomendations (if there's one like or easy as using CCS C that'd be great), and which programmer to use.

Any info/help would be great.

Many thanks, Kurt.
Kurt

If you want to make your own, start with the $50 robot one, but go into eagle and design one with everything you want.

If you want to buy one the Axon has everything you need I think, or wait for the Axon 2

I just need some part numbers that could support that and then some, maybe ones that others have used. and on the topic of the Axon, I will eventually get one but I'm more so on the DIY aspect of robot controllers.

PS I will need something that is powerful enough for my requirements and preferably in a socketable DIP pinout.

the mcu in this URL http://www.tincantools.com/product.php?productid=16133&cat=0&page=1&featured is quite expensive but incorporates a fast arm9 with additional memory and you solder header pins to make it pinout to a wide dip socket.

 It is expensive but there are similar type things coming out now that support PIC32's , and renesas mcu's you might find something similar with AVR's but look around for something like this, the boards are DIP compatible and you get high end performance(really required for blob tracking, ignore any low end mcu's like $50 robot board if you need advanced features)

Thank you very much, I'll probably look into that ARM board.

I am wondering for Atmels ARM7 based MCU's is there any good C compilers in which they can be coded with? and can I use a standard AVR programmer with them or do I have to use the JTAG interface?

The MCU I have in mind is the AT91SAM7S512, or something within that series.
