[ECOS] hal_platform_setup.h usage

[Alexandre]

Hey everyone,

I'd like to use the macros included in the hal_platform_setup.h file.
How can I do that ?

They are not designed to be used from application code.

Which macros are you interested in? What are you trying to do?

I'm trying to initialize my eval board and use the leds on it.
I saw the macro
.macro _led x
on that file and thought i could use it -.-

Is writing to the LEDs that complex that you can't just rewrite the
code somewhere else? I would think that toggling some LEDs would be
simple, and providing a function in C even easier than the assembly.

You can use that macro within the setup code, ie inside
hal_platform_setup. For application code there is often a
function, eg the AT91 boards have hal_at91_led().

Actually it's quite simple to toggle the leds, i was inquiring if
there was some "eCos way" to do it :)

Thank you andrew i found the hal_lpc2xxx_set_leds() function, that's
exactly what i was seeking for !

So if i understand things correctly, the whole hal_platform_setup
thing is launched at startup ?

Can i modify that file to fit my platform specs ?

I'm using the olimex lpc2106 eval board package on an IAR kickstart
lpc2106 eval board and some things are a bit different here and there.

And additionaly, the function
externC void hal_lpc2xxx_set_leds(int mask);
is defined as is in hal_diag.h
Do you happend to know where the full definition is ? (do i have to
write it myself ?)

Correct. Take a look at the HAL porting guide. It should tell you more
about how the startup sequence works.

You might want to make a new HAL package based on the nearest match.
Look at the porting guide and other HALs for ideas.
