I hope it helps.

I just started a blog dedicated to Embedded Programming & RTOS Tutorials at https://polisoftdesign.com/blog.
While the examples may look trivial for some, I'm sure others will find them useful. Few topics covered:
- development tools
- writing peripheral...
Re: MMC/SD FAT file system
Here are some resources you may find useful:

Re: rtos development
One of the best books on how an RTOS works is "uC/OS II" by J. Labrosse. There is a new edition "uC/OS III" that comes with an evaluation board so you can start playing right away.
Otherwise, I suggest looking for tutorials on Internet. There are plenty but it is hard to...
There are a lot of resources related to RTOS on Internet. Just do a search and you will find plenty. As for ARM development tools you can find many as well.
I suggest you buy an evaluation kit that usually comes with either a lite edition of a major tool chain or with a fully functional GCC...
lm628 cost
Building a servo using DC motors will imply some circuitry like:
- position encoder;
- motion controller;
- motor (H-Bridge) driver;
- eventually, an interface to the main controller.
You may start reading the documentation of a motion controller like LM628/629 from National...
Hi Igni,
Here is my assumption (please note that I didn't use CAVR, but ICCAVR as a programming environment). I remember that I had some difficulties to set up everything until the moment I realized that ATmega128 comes in ATmega103 compatibility mode (see...
You're right. When I mentioned STK500 for ATmega128 I considered "everything included" (i.e. all the accessories like STK501, cables, etc). Sorry for the omission.

My setup (see the previous message) works fine and is cheap. You can find one (i.e. STK300) for about $70 (https://www.kanda.com). Replace your ATmega103 with ATmega128 and you'll obtain a simple development system. For the J-Tag debugger it might not work. I recommnend the newer STK500 that...
Hey guys,
You gave me something to think about these days. I wouls like to thank you all for advise.
I'll be trying some of your ideas soon, when ordered LM629-8 will arrive.
Keep you in touch,
OldMan
You're right. I tried this several days ago, but with poor results. I suppose it was my fault, because I didn't use an inductor (i.e. LC filter) but a resistor (RC filter) and the capacitor was too small. Next time I'll try to build a better filter... On the other hand, in order to keep a good...
I agree with you: I ordered two new LM629 controllers capable to work at 8 MHz (i.e. f(PWM) ~16 kHz). On the other hand, I tried to find other motion controllers...
- HCTL1100 can achieve 20 kHz at 2 MHz clock frequency.
- PMD makes a number of motion controllers IC's that operate at 25 kHz.
- A...
In my case I cannot enclose the whole thing in a cabinet (or even in a box) because the whole controller (including motors) must fit a very constrained space. Yes, I can add some polyurethanic foam (or something like that) around the motor (and this is what I'm going to do next, in the same time...
Image*cr@ft I*C*C*A*V*R it is really a great tool for productivity in simple to medium complexity projects. The generated code is acceptable in size and speed, but I*A*R code is better. I discussed with an Atmel representative and he told me that some of their firmware never worked with...
I designed a motion controller for a small DC motor (see **broken link removed**) that uses a 512 lines encode (see **broken link removed**) and a zero backlash 1:76 gearhead (see **broken link removed**). The main job is done using LM629 motor controller (National Semiconductor -- 8 bit PWM)...
