LP-AM243: Trouble integrating gpio R/W/Int into same project

Thank you guys for your help! Much appreciated with our team

Hi Justin,

Ok, I'll start with #1.

I see you have a CCS project named "gpio_input_interrupt_am243x-lp_r5fss0-0_nortos_ti-arm-clang", and this code in the GPIO ISR:

    /* Get address after translation translate */
    ledBaseAddr = (uint32_t) AddrTranslateP_getLocalAddr(GPIO_LED_BASE_ADDR);

    GPIO_setDirMode(ledBaseAddr, GPIO_LED_PIN, GPIO_LED_DIR);
    for(int i=0; i<5; i++)
    {
        GPIO_pinWriteHigh(ledBaseAddr, GPIO_LED_PIN);
//        ClockP_sleep(1);          // was getting stuck here @ runtime
        GPIO_pinWriteLow(ledBaseAddr, GPIO_LED_PIN);
//        ClockP_sleep(1);
    }

Is this the code that doesn't work for the GPIO write?

yep! Thanks Frank, this is the code taken from the subdir '/gpio_led_blink_am243x-lp_r5fss0-0_nortos_ti-arm-clang/' in 'gitlab.com/jmreina/ti_gpio_debug' listed above

Frank you are my hero - thank you.

See repo for update (HEAD:#5F30), I used the following procedure -

1. Confirm write demo (#45A1)
2. Add GPIO input to SysConfig for SW5 (GPIO1.54 @ B9 to example.syscfg)
3. Compile (generate SW5 #defines for access)
4. Add initialization ( GPIO_setDirMode() for SW5)
5. Read & repeat! ( GPIO_pinRead() for SW5 )

This is really clear to me now and I have confidence in the generated solution, thank you Frank :)

Hi Justin,

I'm glad it's working for you! I'll close this thread for now.

Frank
