Lecture 11: External interrupts (EXTI) 

Best video series ever

do you have video that talk about direct memory access(DMA)?

thanks vrey goood work

Where can I get this book?

I wanted to use the PE4 pin, but the compiler shows an error, it only accepts EXTI0 - EXTI3 registers, what's the problem? The documentation and implementation are completely incomprehensible... I prefer to use pe3? According to the documentation, i can use all of them from 0-15, but how...?

Very good

Can you explain AFIO

Questions: 1- How can I declared an ISR with other name with the GCC ARM CROSS COMPILER? 2- What would happen if I wrote a number one in the Enable interrupt register and in the Disable interrupt register at the same time and for the same interrupt. Would the interrupt be enabled or not?

while (1){ THANK YOU SOOOOOOOOOO MUCH }

2:37 PA3 is connected to the 3 volts, how do you mess that up?
