Title: fresh project
Post by: neil on September 18, 2008, 09:27:37 AM
Hi mark,
  I am about to start a fresh project (just for testing), on my own board. Is there any I/Os that are used (for demo and eval boards) in utasker that I have to be aware of,as  I use varoius pins on my own board.

Thanks
Neil

Hi Neil

The demo uses quite a number of ports but these are all defined in app_hw_m5223x.h.
By removing USE_MAINTENANCE a lot of this is removed, including the call to fnInitialisePorts(); from application.c

The port use is probably easiest to see by running the simulator. It is quite easy to move the ports around (defines in app_hw_m5223x.h) or remove them and quickly verify that they have really been freed.

Regards

Mark

Hi Mark,
  I have removed the USE_MAINTENANCE, and all the LED outputs, apart from the ethernet ones.

Can the below be removed? :
INIT_WATCHDOG_DISABLE() ;// ensure IRQ4 is an input
#define CONFIG_TEST_OUTPUT()       PORTTC |= PORT_TC_BIT3; DDRTC |= PORT_TC_BIT3; // {27}
#define TOGGLE_TEST_OUTPUT()       PORTTC ^= PORT_TC_BIT3;
WATCHDOG_DISABLE()// pull this input down to disable watchdog (enable debugging) {3}

Regards
Neil

INIT_WATCHDOG_DISABLE(); is used to configure an input to decide whether the watchdog is to be activated or deactivated (useful for debugging). You can set

#define INIT_WATCHDOG_DISABLE() // do nothing
and then also
#define WATCHDOG_DISABLE()  0    // always activate the watchdog
or
#define WATCHDOG_DISABLE()  1    // always deactivate the watchdog

The others can be removed by setting
#define CONFIG_TEST_OUTPUT()       // dummy
#define TOGGLE_TEST_OUTPUT()      // dummy

These are some LED outputs used during some of the demo tests (or for measuring program execution times etc.)


regards
