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

while (1){ THANK YOU SOOOOOOOOOO MUCH }

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?

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