This is related to my "D'oh post" regarding the Cortex M4 floating point size. According to ARM, the Cortex R4 supports double-precision floating point, and it looks like it's maybe more amenable to embedding than the Cortex Ax cores. I really want to find a chip that I can just lick the back of and stick onto a board, rather than something that'll become the CPU in a built-up comput...

Hi, I'm working on a project which is currently planned to use an ARM Cortex M3 from ST (device is from the STM32L151xC series). I've never used the Cortex chips before and my ARM experience is quite limited too, is anyone here prepared to give me the executive precis of the state of the compiler/debugger situation for these chips ? If I'd been asked the same question 10 years ago a...

Hi I am looking into using the ARM Cortex M family for a new project. I like the Cortex M series, since in "principle" code should be pretty simelar from one device to another, if you limit the functionality to the core and some limited periphials. Just released is the M0+ with only 9uA/MHz current consumption and that would fit well for a small application. So, if it is possible to d...

Trying to learn about the ARM Cortex M3 solution for low cost embedded market. Their web site isn't much more than a shallow advertisement. http://www.arm.com/products/CPUs/ARM_Cortex-M3.html The "datasheet" is a two sheet sales flyer.

Hi! Does anyone know of a tool that will generate svf files (or something simillar) for ARM cortex based micro's. I've actually got an STM32 but which flavour of cortex shouldn't matter. This is the means by which a production JTAG interconnection tester (JTAG technologies in this instance) programs CPLDs, micro's or other simillar stuff. At the moment we are just using an open source co...

Hi So, considering going the Cortex Mx route for project with new microcontrollers at our firm. Has anyone a feeling/information about the development speed of the ARM Cortex Mx series vs the rest of the industry?

Best dev kits for ARM Cortex?

Hi I've started porting a project from an 8 bit AVR to an ARM Cortex M3 MCU. I'm reasonably comfy with AVR, but I'm new to ARM Cortex. I found an NXP part that looked great, price and feature wise. I purchased an inexpensive LPCXpresso dev kit. However, the drivers and example code is simply awful. Buggy and poorly written, so development is more like reverse engineering than making actual p...

See: http://mcu.st.com/mcu/inchtml.php?fdir=pages&fnam=stm32 (and: http://www.freertos.org/portstm32iar.html :o) The Cortex-M3 marketing has trumpeted greater interoperability between vendors as one of the M3 selling points, so it is interesting to note that the FreeRTOS.org demos for Luminary Micro and STMicroelectronics Cortex-M3 parts use exactly the same port code, while the port...

Dear community, I bought a TI RM57L Launchpad and Segger J-Link EDU emulator several days ago. The core is ARM Cortex-R5. I'd like to debug codes with J-Link emulator. Since IAR EWARM supports both J-Link and Cortex-R5, I decided to write code for the launchpad using IAR EWARM. Although I had googled a lot, I was not able to find any nice tutorial for the following topic: Programming on ARM...

I notice that the ram capacity (ignore program flash for now, but it tends to basically be proportionate) of microcontrollers seems to grow fairly continuously (say in 2x jumps) from very small (a dozen or so bytes in an 8 bitter, lots of MSP430's in the 128 to 1k byte range, Cortex M0's with 4k, etc.), up to about 32k (Cortex M4). Above that there are a few chips with 64k or 128k, that are ...
