NEW on Cortex-M3 STM32F103B IAR

Hi everyone,

I recently got an Arm cortex m3 microcontroller (stm32f103B). I'm interested in programming in C. I received some software with the kit I bought (IAR workbench kickstart) but i find all of these a little confusing to use. Reading the book "the definitive guide to arm cortex m3",
i found that's describing assembly instructions,

I ask, if there is an other guide wich describes C instructions?

    Hi ,

    thanks a lot Joseph.

    I'm working, benchmarking of real-time performance of the present SOC, (tail chaing, Systick, context switch and other performance to specify after)

    1- how can I show the importance of latency and jitter in C coding (systick with GPIO?!)  (refering to this document: rtos-comparison-EN.pdf ).
    2- hwo can show me, a code in C that details a cotext switch.
    3- DMA multilayering communication between interfaces and memories is the default configuration in cortex-M3; how can i show the importance of this feature, in benchmarking.

    Note: benchmarking with oscilloscope on GPIO of STM32F103B IAR.
