2.5 User Buttons

User buttons are connected as followed:

Figure 1-9: Buttons SW1 and SW2 at EVK-Apollo-Base

SW1 connects to GPIO28 and SW2 to GPIO17.

2.5.1 Drive buttons via GPIO

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):

#define APOLLOGPIO ENABLED 1

Add apollogpio.c to your project and include apollogpio.h in you C-file. Following code gives

an example how to poll the GPIO:

#include "mcu.h"

#include "apollogpio.h"

int main(void)

{

ApolloGpio_GpioInputEnable(PIN_GPIO28,TRUE);

ApolloGpio_GpioInputEnable(PIN_GPIO17,TRUE);

while(1)

{

if (ApolloGpio_GpioIsSet(PIN_GPIO28)) //button SW1 is pressed

{

//do the script executing code

}
