learn the ARM CORTEX M3

[mahmoudathab]

what is the best way to quickly learn the ARM CORTEX M3 programming? I already have 2 books that I am reading but I am talking mainly about practical knowledge.

Buy a starter development Kit

I already ordered one...but it will take about a month to arrive ...any other advices?

You can do some simulation at demo firmwares on IDE compiler, however it will not perform real result. due simulators don´t match perfect work of built-in hardware modules.

Nice board.

how can i port android on lpc1788 ?

I´m not sure if you can do that with cores less than ARM9 / ARM11 / Cortex -M4 / Cortex -A8 / etc...

thanks for the replay.

now i am looking for external flash accessing programming.

how to store an image array in external flash ?
iam using j-link usb-jtag and keil uvision 4.70.0.0.


thank you.

 

[andre_luis]

The starter kit you buyed don´t have library or example programs to do access to flash memory ?
