This example describes how to configure external interrupt lines.
In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 and APB2 clock is from Main clock.
In this example, EXTI0 is configured to generate an interrupt on the rising edge. EXTI6 is configured to generate an interrupt on the falling edge.
In this example:
After EXTI configuration, a software interrupt is generated on the EXTI0 toggles LED1. After that, when rising edge is detected on EXTI0, LED1 toggles when falling edge is detected on EXTI6, LED2 toggles
In order to make the program work, you must do the following :
