2.7.1 Using Digital IO
Digital IOs are available as A0…5 and D0..D13 and D18..19. Digital IOs can be also directly
addressed by using GPIO0..49.
The Naming is: ARDUINO_A<x>, ARDUINO_D<y> or PIN_GPIO<z>
Start with the FEEU MCU Temlate for Apollo 1 or Apollo 2. Enable GPIO FEEU Low-Level-
Driver for Apollo in
RTE_Device.h
(in
example\source\config
):
Add
apollogpio.c
to your project and include
apollogpio.h
and
skamapollobase.h
in you C-
file. Following code gives an example how to poll the GPIO:
#define APOLLOGPIO ENABLED 1
#include "mcu.h"
#include "skamapollobase.h"
#include "apollogpio.h"
int main(void)
{
ApolloGpio_GpioInputEnable(ARDUINO_D0,TRUE);
ApolloGpio_GpioOutputEnable(ARDUINO_D1,TRUE);
while(1)
{
if (ApolloGpio_GpioIsSet(ARDUINO_D0))
{
ApolloGpio_GpioSet(ARDUINO_D1);
}
else
{
ApolloGpio_GpioClear(ARDUINO_D1);
}
}
}
