- Where do i start?
- Posted by Xarion on July 26th, 2005
Hi everyone
I have been desing hardware based on the C51 architecture in assembly code
I am wanting to migrate to ARM and and wanting to start writing in C rather
than assembler. can anyone give me any site that could help me out with
this, like writing to registers, changing modes, dealing with interrupts
etc.
Thanx!

sdcc is a C compiler for c51 and it's free
the datasheet of the microcontroller is the first place where I look for
basic things , application notes are the second and third there is
google :-)
you can easily find code in asm or C for many tasks.
always check for compatibility between derivatives of the chip (
different chip different registers and peripherals )
oh , a simple sbc withe micro and ram is useful.

Think i might have mis-communicated my point
I am wanting to develop new hardware with ARM micros and am looking for some
sort of introduction into c programming for ARM architectures. I have been
through ARM's website and haven't found anything that could help me starting
with ARM its more for people already working with ARM.

So, have you seen the App Note 34 "Writing Efficient C for ARM" in

Try looking at some of the C source code examples associated with an ARM
evaluation kit (for example, Atmel's AT91EB40A...
http://www.atmel.com/dyn/products/to...b&tool_id=2717
While they are specific to a particular implementation (product) they do
provide real examples of low level software written in C (i.e. accessing
registers in devices, interrupts, etc.). There are probably better links...
but this is one I knew of.
