|---|---|---|---|
| EINT0 | P2.10 | ISP | EINT0 |
| EINT1 | P2.11 | USB_BOOT | EINT1 |
| EINT2 | P2_12 | 30 | EINT2 |
| EINT3 | P2.13 | 31 | EINT3 |
Hardware Connection
LED is Connected to pin 13 on Explore M3 board.
Code
Below is the sample code to blink the LED's with 1ms delay using systick timer.
