Given an application requirement, at which point do you decide that the simple 8-bitter is no good and start looking for an ARM processor ? If there is any doubt that an 8-bitter won't hack it, then don't waste any effort trying to force it: I said:
It certainly means that there is really no point in struggling with and 8051-based design when a Cortex would be a breeze (ie, when you're struggling with things like code space, data space, or any other specific limitation due to the 8051 architecture).
http://www.8052.com/forumchat/read.phtml?id=156744 If you're looking for a (relatively) small step up from 8-bit, then I certainly recommend that you should start with Cortex-M3; eg, http://www.luminarymicro.com/ http://www.st.com/mcu/inchtml-pages-stm32.html Given thier low power needs, are ARM s only preferred on mobile apps ? Absolutely not! ARMs are just as "General Putpose" as the 8051! http://www.arm.com/markets/showcase/ What about development tools like compilers etc ? Are there any free C-Compilers for ARM processors ? Yes, there are plenty of free tools based on GCC, Eclipse, etc; eg, http://www.luminarymicro.com/products/...ducts.html http://www.st.com/mcu/incht...tools.html |
