Pin-Interrupts in Energia (and Arduino) are only for digital pins. RISING means the value of the pin changed from LOW to HIGH. You could use this to detect when a button is pressed.
make sure that you input pin is pulled up. You can do this with pinMode(sensorPin, INPUT_PULLUP);
Also note that A5 is indicating an analog channel. A5 when using it in any of the digital API's translates to pin 5 which is P1.3.
So rather than using int sensorPin = A5; I suggest that you use uint16_t sensorPin = P1_3.
Since count is being increased in the interrupt routine, you will need to make it a volatile. Simply said, volatile means that the value can change at any time. so that would be volatile uint8_t count1;
Below is a small example that will toggle the red LED when the button is pushed.
int pin = RED_LED;
volatile int state = LOW;
void setup()
{
pinMode(pin, OUTPUT);
pinMode(PUSH2, INPUT_PULLUP);
attachInterrupt(PUSH2, blink, CHANGE);
}
void loop()
{
digitalWrite(pin, state);
}
void blink()
{
state = !state;
}
