Does anyone have a copy of MPLAB or XC8 -- AVR includes?

Specifically whatever they're using for avr-libc, because AVR-DA isn't supported by any version that exists on the internet.

(And no, I'm not installing that pig just to grab a few hundred bytes of plain text, that's asinine.)

These are zip files so just rename it, open it and find what you wanted.

Appreciate the effort, but those are io headers, not avr-libc.  You know, inc/ and inc/avr/*.h, other than io*.h's.

Have you looked at the github repository of avr-libc?

[T3sl4co1l]

They don't Github, officially speaking:
http://svn.savannah.gnu.org/viewvc/avr-libc/trunk/avr-libc/
Most of it around 6 years old.

There's an updated fork here:
https://github.com/stevenj/avr-libc3
but again no AVR-DA.

Why would libc headers need to be changed for DA???

More stuff attached.

Compare sleep.h, old (from line 140):

Code: [Select]

/* Define an internal sleep control register and an internal sleep enable bit mask. */
#if defined(SLEEP_CTRL)

    /* XMEGA devices */
    #define _SLEEP_CONTROL_REG  SLEEP_CTRL
    #define _SLEEP_ENABLE_MASK  SLEEP_SEN_bm
...

new:

Code: [Select]

/* Define an internal sleep control register and an internal sleep enable bit mask. */
#if defined(SLEEP_CTRL)

    /* XMEGA devices */
    #define _SLEEP_CONTROL_REG  SLEEP_CTRL
    #define _SLEEP_ENABLE_MASK  SLEEP_SEN_bm
    #define _SLEEP_SMODE_GROUP_MASK  SLEEP_SMODE_gm

#elif defined(SLPCTRL)

    /* New xmega devices */
    #define _SLEEP_CONTROL_REG  SLPCTRL_CTRLA
    #define _SLEEP_ENABLE_MASK  SLPCTRL_SEN_bm
    #define _SLEEP_SMODE_GROUP_MASK  SLPCTRL_SMODE_gm
...

AVR-DA are xmega2 core, but don't have the same registers.  Old headers get the error (on using sleep_enable():

Code: [Select]

main.c|237|error: 'MCUCR' undeclared (first use in this function); did you mean 'MCU'?|
which occurs because the above #if-else falls through to the default (!defined(__DOXYGEN__)) case.

Oh interesting, stdlib.h doesn't define itoa family.  Easy enough to fix.

That does it, thanks!

Edit: Let it be known, I have stumped the internet at large.  Searching for "_SLEEP_SMODE_GROUP_MASK" as a keyword turns up only:
https://www.avrfreaks.net/forum/attiny104-power-down-mode-and-external-interrupt
which, as far as Google knows, is the only example in the entire internet (or, second once this post gets indexed shortly).

Some of these things you are better off dealing with yourself. A few lines of code, stick it a header, and you are all set. No need for a library to do all this for you.

Code: [Select]

//Slp.h
#include <avr/io.h>
typedef enum { SLP_IDLE, SLP_STANDBY, SLP_PDOWN } slp_t;
static inline void slp_sleep(slp_t e){
    SLPCTRL.CTRLA = (e<<1)|1;
    sei();
    asm("sleep");
    SLPCTRL.CTRLA = 0;
}
Compare what you then get-
slp_sleep( SLP_PDOWN );

vs what libc will make you do, if you can figure out what all the macros are up to.
