I am a begginer with MCUs.
Could you please suggest a development board kit.
Which comes with JTAG.
There are several good options:
The Arduino Uno is a good C language based entry level platform, with lots of community support out there.
The Basic Stamp by Parralax is an easy to learn Basic language based platform, perhaps not quite as powerful as the others.
TheTI MSP430 Launchpad is very inexpensive, but has a little steeper learning curve.
Every single microcontroller manufacturer makes a low-cost development system with lots of software and, I think, alwys with a JTAG port.
I would pick the processor first. Use the Embedded Developer (www.embeddeddeveloper.com) web site to find an iteresting MCU - this site has a bunch of options you can put in to help you find the right device or devices. Then use their "Developer Tools" section to see what is available for that chip.
I love the propeller... Started with the basic stamp from parallax which is great for being easy but it's limitations come up fast... The propeller has been a blast!
I'm not one to continue reviving an old post, but there is an excellent podcast for those who would like to learn the Parallax Propeller platform.
The crew does a good job going over micros, the propeller, and spin language from the ground up.
I started out with Basic Stamp. I switched to Arduino. Very happy with that decision. There are faster devices out there, but the arduino has a nice mix of power. approachability, and user community support. http://arduinotronics.blogspot.com
I'm interested in this as well, however, to make it more challenging, I need a board for students to use in a class. The processor needs to be MIPS based to match the book. There needs to be an available assembler so the students can program some pieces of assembly language. It needs to have some "interesting" gadgets on the board the student can interface with. The price needs to be reasonable for a student to pay (less than or equal to a text book).
I found a really great board, mikromedia for PIC 32 by MicroElectronika, which met all of the criteria. Really neat graphics, reasonable price, etc. Except, it needs a commercial compiler/assembler that runs $250 a copy, which is totally unreasonable for a student to buy and no student discounts (I asked). I could jury rig it with MPLAB, but then we lose the graphics support and the setup becomes challenging for students.
Open to ideas.
