I started learning embedded programming. But there are many things which is not understandable!
There are many things like USART, GPIO, DMA, SPI, I2s, I2c....... and others.
I have manual and other docs of STM32F407 board. And also I download some peripherals code examples.
Could anyone help me how to use this documents or how to use peripherals? For example, to blink some LEDs, should I use GPIO or USART? Which should I use? How can I find these information on documentation?
Sorry in advance, if these questions are dummy or stupid. Because I studied almost for a month and there is no result.
