am working with the MPC5748G DevKit and the S32 SDK.
In the "Component Inspector" (pin_mux:PinSettings) i'm able to set the GPIO's Input/Output (SIUL2 Mask)
The Pin component (pin_mux:PinSettings) is offering me some functions which i can drag'n drop into my code.
Now i want to set a GPIO resistor pull-down or no-pull, active high or active low.
Are there functions for GPIO settings? I can only find functions which handle Ports, like PINS_DRV_SetPullSel().
Or do I have to config the GPIO directly like SIUL2->GPDO[x] = SIUL2_GPDO_xxxxx
Thanks for Info!
you can configure GPIO pins behavior in processor expert -> Pin Mux settings -> Functional Properties
For pins with external interrupt functionality also can be set interrupt edge.
In runtime - you can drag and drop
function. In row above for PORTJ, pin 0 and Pull down. You need to fill up parameters manually.
Hope it helps.
I still have a question.
How can I config a GPIO (output) logic active high or low?
(GPIO128, output, no pull, active high)
// config GPIO 128, output, no pull -> like in processor expert -> Pin Mux settings -> Functional Properties
SIUL2->MSCR = SIUL2_MSCR_OBE(1) | SIUL2_MSCR_IBE(0) | SIUL2_MSCR_PUE(0) | SIUL2_MSCR_PUS(0);
// config GPIO 128 active high
SIUL2->GPDO[128/4] = SUIL2_GPDO_PDO_4n3_MASK; // something like this?
um, if you mean just set pin output (set the particular pin to High or Low) - you can use SDK functions
PINS_DRV_SetPins(PTD, 1 << LED);
where led is connected to PTD PIN 1 ==> #define LED 1
If you mean some kind of negative logic - like if I wirte 1 to output buffer and want physical output 0V on pin pad - I'm afraid that there is no such feature. Only some special I/O may have this settings (like I2C ... ).
