Detailed Description
A multiple pin digital output.
- Note:
- Synchronization level: Interrupt safe
Example:
// Toggle all four LEDs #include "mbed.h" // LED1 = P1.18 LED2 = P1.20 LED3 = P1.21 LED4 = P1.23 #define LED_MASK 0x00B40000 PortOut ledport(Port1, LED_MASK); int main() { while(1) { ledport = LED_MASK; wait(1); ledport = 0; wait(1); } }
