Hello everybody,
As the senior expert I have worked with ATMega2560 so much, but I have to choose the ARM micro-controllers for my new projects.
I have also read a lot about ARM7TDMI,focusing on how to write SWs with Keil...but I haven't had any practical experience yet.
With the extraordinary improvements of the ARM technology, it seems that ARM7TDMI should be ignored and we need to know about new products.
Can anyone help me about finding very good PDFs or free useful e-books about ARM cortex M?
I have to ask the same questions about RTOS and working with Linux and so on, running on the ARM microcontroller.
Is there any free training course on the Internet?
Your consideration is highly appreciated.
Regards:
Hossein.
Hi Hossein.,
Documents (Reference Manuals, Developer Guides, Application Notes, Tutorials, etc.) are available here, ARM Information Center.
These books are useful but are not free:
The Definitive Guide to ARM® Cortex®-M3 and Cortex®-M4 Processors, Third Edition
by Joseph Yiu
ISBN-13: 978-0124080829
ISBN-10: 0124080820
The Definitive Guide to ARM® Cortex®-M0 and Cortex-M0+ Processors, Second Edition
ISBN-13: 978-0128032770
ISBN-10: 0128032774
Other titles can be found here, ARM Related Books.
RTOS
Here are some RTOS available for ARM Cortex-M:
eCos
FreeRTOS
RTX Real-Time Operating System
ThreadX for ARM
μC/OS or μC/OS for Makers
Linux
You stated "ARM cortex M". Linux is a large OS supporting GUI, file system, networking, among others. For ARM processors, Linux is generally for devices using the Cortex-A profile. The reason for this is the need for large amount of memory and MMU. Fortunately, at least one exception exists in the form of uClinux. See EmCraft SYSTEMS - Linux for Cortex-M. While uClinux does not need an MMU, large amount of Flash and SRAM is required. Also, the processor must be able to run at high Speed. Currently, only high-end Cortex-M3/M4 MCUs satisfy these requirements. Maybe uClinux will also become available on Cortex-M7 soon.
Free comprehensive training courses are available on the Internet, that one in mirosamek's blog is a good example. These resources are also helpful:

Hossein,
I would recommend the free "Modern Embedded Systems Programming" video course on YouTube. The course starts from the beginning and is structured as a series of short, focused, hands-on lessons that teach you how to program ARM Cortex-M microcontrollers in C. The course now has grown to 20 lessons and it is headed to cover RTOS and other related concepts.
If you are already familiar with AVR you can use the Atmel Studio 7 and Atmel Start development tools for Cortex families as well.
Hi,
first of all, you had better read White Paper: Cortex-M for Beginners - An overview of the ARM Cortex-M processor family and comparison . It would be very helpful.
Best regards,
Yasuhiko Koumoto.
Dear Liviu,
Thank you for your reply.
> e-books about ARM cortex M
I highly recommend The Definitive Guide to ARM® Cortex®-M3 and Cortex®-M4 Processors, Third Edition: Joseph Yiu
for free development tools, you can take a look at GNU ARM Eclipse
as for RTOS, if you don't mind lots of macros and unusual names, you can check FreeRTOS
for a modern C++ solution, you can follow CMSIS++: a proposal for a future CMSIS, written in C++ , currently under development.
