digital sampling of GPIO

Question asked by ml.michal on May 26, 2013

is it possible to sample GPIOA Bit7-0 into SRAM as byte and to have kind of "Clk" nonPWM output on other GPIO ,
with higher speed than 20MHz on STM32F103 72MHz ?

this gives me 10MHz clk output on PC2:

 Buffer_ptr=(uint8_t *)Buffer;
 while( 1 )

    GPIOC->ODR = GPIO_Pin_2;

    if(Buffer_ptr>=(uint8_t *)(Buffer+20000))

    GPIOC->ODR = 0;

Thank You for all replies
