Getting control over port TC

[Marc VDH]

Hello Mark,

I would like to use port TC in my application, but this port is already being used by uTasker itself for the blinking LEDs.
Is there a simple, straightforward way to disable the uTasker use of this port, or do I have to go through the code to remove all uTasker use of that port myself?

Hi Marc

The demo project configures some ports and also blinks one output.

To remove these the following can be done:

1) In application.c comment out

        fnInitialisePorts();                                             // set up ports as required by the user

Without this the initialisation of the demo ports will not be performed.


2) In app_hw_m5223x.h remove the blink LED configuration and the blink activity

    #define INIT_WATCHDOG_LED()        _CONFIG_PORT_OUTPUT(TC, PORT_TC_BIT0)
    #define TOGGLE_WATCHDOG_LED()      _TOGGLE_PORT(TC, PORT_TC_BIT0)

This is done by using empty defines:
    #define INIT_WATCHDOG_LED()
    #define TOGGLE_WATCHDOG_LED()

This should leave all ports which are not used by peripherals free for use by the application.

Regards

Mark
