Posted on January 07, 2012 at 06:09Hi,I am curious as to what the '50MHz' output speed of the GPIO ports refers to (with correct configuration bits set). Is it the maximum frequency of a square wave output, or does it have something to do with the r...

Posted on January 05, 2012 at 04:46Hi, I'm quite new to the STM32 and am trying to run code in internal SRAM, but cannot find a lot of information about it.This is what I have been doing:1) Copy code block to SRAM (with LDR and STR) starting at 0x20...

Posted on January 07, 2012 at 17:38Thanks for your input, I'll be able to get my hands on a scope in a few days so I guess I'll just wait until then. The prescaler value is left at default - zero, but some strange things are happening.

Posted on January 07, 2012 at 16:25Thanks for the response;I am using a timer (in output compare mode) to create a waveform. Also, I am not using any interrupts. I simply need to generate a square wave of 12Mhz. The same thing happens when the pin (...

Posted on January 07, 2012 at 03:33Yes OK, I meant that I need to actually program code, rather than just select 'run from SRAM' in so-and-so menu! I know that there is more than Keil out there 

Posted on January 05, 2012 at 19:59Thank you for your help - adding 1 to the SRAM branch address worked perfectly! However, I was also able to execute 32 bit instructions in the SRAM?!The code I am working on is extremely time-sensitive, because my ...
