µTasker general / Changing maximum clock delay

« on: February 04, 2009, 04:26:10 PM »

Hello,

I wanted to change the maximum clock delay allowed when calling uTaskerGlobalMonoTimer() to a 32-bit time. Right now in types.h I see:

typedef unsigned short  CLOCK_LIMIT;

Can I just change that to unsigned long? Is there other types I have to change too?

Thanks,

ATMEL^TM AT91SAM7X and AVR32 / Makefile syntax

« on: January 14, 2009, 11:39:45 PM »

Hi,

I was curious why the uTasker makefiles seem a little 'crazy'? aka they use hard links everywhere, rather than having one 'SRC =' section where all the source files are used?

And for instance lines like this:

Code: [Select]

Build\startup_gnu.o: ..\..\..\Hardware\SAM7X\startup_gnu.s uTaskerV1.3_FLASH.ld
$(GCC) $(C_FLAGS)  -D _GNU -D _HW_SAM7X -g -c -Os ..\..\..\Hardware\SAM7X\startup_gnu.s -o Build\startup_gnu.o

Can be replaced by using the $< and $@ to get the first and second argument, so you don't have to change things in two places:

Code: [Select]

Build\startup_gnu.o: ..\..\..\Hardware\SAM7X\startup_gnu.s uTaskerV1.3_FLASH.ld
$(GCC) $(C_FLAGS)  -D _GNU -D _HW_SAM7X -g -c -Os $< -o $@

Just seems a little unusual compared to how most make files I see!

ATMEL^TM AT91SAM7X and AVR32 / Problems compiling on GCC

« on: January 06, 2009, 03:45:05 AM »

Hello,

I was compiling uTasker on GCC using YAGARTO, and came across a few problems/bugs:

#1:

SAM7X.C, line 255:

Currently reads:

Code: [Select]

    #if defined _GNU || define ROWLEY
Should be:

Code: [Select]

    #if defined _GNU || defined ROWLEY

#2:

..\..\..\Hardware\SAM7X\SAM7X.c:850: error: invalid storage class for functio
fnPhyInterrupt'

This is due to a change in recent versions of GCC I think... the function decleration needs to be moved outside the function, as so:

Code: [Select]

#ifdef SUPPORT_PORT_INTERRUPTS
    #if defined INTERRUPT_TASK_PHY
    static void fnPhyInterrupt(void);
#endif
#endif

// Ethernet configuration routine
//
extern void fnConfigEthernet(ETHTABLE *pars)
{
#ifdef SUPPORT_PORT_INTERRUPTS
    #if defined INTERRUPT_TASK_PHY
    INTERRUPT_SETUP interrupt_setup;                                     // interrupt configuration parameters
    #endif
#else
    __interrupt void PortB_Interrupt(void);                              // phy interrupt
#endif
