How to control GPIO?

Hi,

I'm using the STM32F103ZE uC on the MCBSTM32E development board.
I tried the example programs, they all compile and download and run fine, but they are NOT SIMPLE. They use a lot of Library files etc, etc, etc.
I just try to make some ports go high or low.

The example GPIO program states:
- Enable the clock signal for the GPIO.
- Configure the Alternate Function to use a GPIO (usually standard after reset).
- Configure the GPIO pins as input or output.
- Set remaining parameters like speed, pull-up/down.
- Enable the GPIO.
- Read from or write to the GPIO.

Can someone give me a simple (and I mean REALLY SIMPLE) program to control just one single GPIO port?

My questions to activate some port:
- do I need something to know about internal clock signals?
- do I need some startup file?

Thanks,

Henk

  • I can't seem to get "stm32f10x_stdperiph_lib_um.chm" working.

    It turns out that on Windows7, the .chm file needs to be in a directory without spaces... I put it in the root directory":

    C:\stm32f10x_stdperiph_lib_um.chm

    And now it works. (whereas it wasn't working in other locations on my C drive. Of course, I made a short-cut to the help file(s) from ST-Microelectronics).

    I thought that others using the STM32 series who might have had an 'issue' with this might benefit from this tid-bit of information.
