Hello,
I've STM32F103VE core & development board. I want to generate 32.768 kHz clock signal at any of the data port rather than OSC32_OUT pin by software.
To be more clear: I want to connect a sensor into STM32F103 and sensor requires 32.768 kHz Master Clock signal. I do not know how to generate it.
Even if STM32 has internal 32.768 kHz clock signal,
how can I direct it into some suitable port ?
Regards
Gokcer
Hi Neil
Yes you are rigth, I can use it. However, I'm using a Mini STM32 board and it is very difficult for me to get a connection with OSC32 out pin - it is too small.
I'm looking for a alternative solution, may be, some software configurable timers can be set and jump into overwritten interrupt handler to generate 32 kHz clock signal..
Or any other solution - I'm new to ARM7 core.
The STM32 is not an ARM7 - it is a Cortex-M3!!
Have you read the User Manual for details of the capabilities of the chip - in particular, its timers...?
As already noted, this has nothing to do with Keil. Keil make software tools; they don't make (or design) chips.
For specific details about particular chips, you need to consult the chipmaker's documentation - in this case, ST.
ST have a page dedicated to the STM32:
www.st.com/.../inchtml-pages-stm32.html
In particular, note the link, Documents and files for STM32F family:
The key documents you require are the Datasheet and the RM0008 Reference Manual...
