Hello Led.

soeren Panduro

HI.

I'm trying my new EV-board MCBSTM32E from Keil.

I have copied the STM32_Init.c and .h file from the Blinky demo project to one project and added STM32F10xR.LIB and my one main.c.

#include <stm32f10x_lib.h>                        // #include "STM32_Init.h"                           //

int main (void)
{
  stm32_Init();// STM32 setup
  GPIOB->ODR = (GPIOB->ODR & 0xFFFF00FF) | (1 << 8);
  while(1);
}

I can debug the code but the led won't go on.
I don't think that's has something to do with the GPIO but more a overall Init problem.

I know that it can be a lot of thing, but I think it's something simple I have missed

Thanks.
Soren

    It's a bit like installing software on your PC: after you install the software, you have to Run it before it will actually do anything.

    Similarly, on an embedded system, "downloading" simply loads your code into the target hardware - a reset or similar is usually needed to actually start Running the newly-loaded code.

    uVision has an option to automatically reset & run the code after a download...
