Stm32 IO Operation header file specification

In Stm32 many project development, there are too many operations on Io, if set 1 or 0, using the functions provided by the official library is convenient, specification, but need to include the standard library, large size, but also to deal with different version compatibility issues, including IO initialization is too cumbersome, so the operation of atoms and other routines to streamline,

Initialization is as simple as this: for stm32f and stm32l

void Init_io (void)
{
Jtag_set (swd_enable);//Open SWD
rcc->apb2enr|=1<<6;//to enable peripheral Porte clocks first
rcc->apb2enr|=1<<5;//to enable peripheral PORTD clocks First
rcc->apb2enr|=1<<4;//to enable peripheral PORTC clocks First
rcc->apb2enr|=1<<3;//to enable peripheral PORTB clocks First
rcc->apb2enr|=1<<2;//to enable peripheral porta clocks First
rcc->apb2enr|=1<<0;//Turn on the auxiliary clock
Jtag_set (swd_enable);//Open SWD
//afio->mapr&=0xf8ffffff;//Clear MAPR [26:24]
//afio->mapr|=0x02000000;//setting JTAG mode

PORTC6~10 multiplexing push-pull output
gpioa->crl&=0xffff0000;
gpioa->crl|=0x00003333;
gpioa->odr|=0xffff;
PORTC Push-Pull output
