Hi Matt- If an RTOS is able to run on one particular implementation of a CPU core, such as a Cortex-M3, does it necessarily support other implementations of that core?

Not sure if this is the right place for this or not, so excuse me if I have not "chosen wisely."

I'm a hobbyist working on a project that I MAY productize and try to sell. I have begun with the mbed platform of embedded boards. However I have…

Hi all!

I'm facing a problem with my UART on a STM32F207IG under CMSIS.

When I try to initialize the UART the processor disappears in the HardFault_Handler.

I think the problem is somehow related to the clock settings which I left untouched until now…

If I have two ARM7TDMI core board and Cortex M3 core board, and I need to choose one of them to use.

What should I consider the different between them and why?

how to configure a I2C in MCB1700 with LPC1758?

I have a MCB1700 board with LPC1758, I am trying to use the I2C on it as a master to run a ultrasonic sensor srf08.

How should I configure the I2C setting on the LPC1758?

There's many references to Debugging a Hard Fault on Cortex-M3 & M4; eg

HI,

i'm an ICT professional (so also with an IT background) and very much interested in embedded development (IoT solutions). Until now I mainly did embedded development (mainly ARM m3, m4 microprocessors based development boards: eg Spark Core, TI CC3200…

For example, is it at the beginning of RAM, user or silicon vendor defined?

I'd like to know such that I can identify the stack boundaries in memory and therefore know if I've caused a stack overflow in my code.

My device is an LPC1778, and Im using…

I'm (trying to) build a device that can receive and play/stream videos wirelessly to an embedded system. I wanted to know what would be the best course to take? If the ARM Cortex-M3 is a viable option for this, do I need a separate video controller…

Greetings,,

what happens if FAULTMASK is set in cortex-m3/m4 and one or more serious fault happened like bus fault, MPU violation, invalid instruction, stack corruption.. etc will the processor enter a lockup? if not what would be the status of the processor…

Dear Friends

                   I am very new to Embedded World especially Arduino and ARM micro controllers. I need to  measure square wave freq upto 8 Mhz using arduino. Can any one guide me in this regard.... Now I am able to measure upto 110 KHz. Here…

I have seen that lot of arm boards are having qnx rtos but all were like cortex-a or cortex-r ,but the soc i have is having cortex-m3 ,so before investing lot of time in this os ,i want to be sure whether at the end it will work with cortex-m3 or not…

I have  to do project on MMC card interfacing and Audio Player on ARM CORTEX M3 ..which hardware and software should I use for it?

how should i start the project...steps to be followed...I am new to this field ...pls help me.

I am looking for some alternative of J-Link Segger for Cortex-M3/4 , the cheapest one is J-Link Base as J-Link Lite can be used only with evaluation boards, 

Any suggestion ?

I am using GNU arm gcc as toolchain and debugger and Eclipse as IDE, I…

Hi Team,

i am completely new to this world, but still i would like to build a solution based on IOT where i can simply sense some object and reflect it status on internet application.

can somebody please guide me with some documentation on how to get started…
