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
Andy,
I can't seem to get "stm32f10x_stdperiph_lib_um.chm" working. I'm not familiar with the help 'books' within uVision.
I tried adding it to the 'books' but that didn't work. Any suggestions?
Yes, I'm trying to utilize STMicro's "new" StdPeriph_Lib_V3.30 libraries, and the help files -- I'm just guessing -- will come in handy.

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.

(I wonder if this post will disappear into the black hole...?)
