Posted on August 29, 2012 at 11:42Hello everybody, I use STM32F103VE with Usart1 and Usart2 as LIN master controllers and Usart3 as standar Usart. But for FW... I find only two pages on reference manual....set relative flags and breif generic dis...
Posted on August 28, 2012 at 14:26Hello! I have already written the code to produce a 40Mhz clock at the output of TIM1_PWM1. I wanted to confirm is it possible to make a 40Mhz clock or not because according to the datasheet , APB2 can have a maxim...
Posted on August 31, 2012 at 05:45Greetings. I find it rather difficult to find some tutorial that would actually provide some insight on the debugging mode. All the tutorials that I have found so far either tell you the benefit of link downloader o...
Posted on August 31, 2012 at 13:33 Hi at all, I am using the STM32F4 i am trying to generate a simple square signal without using an interrupt (about 2MHz). Therfore i tried using Timer 3 in OC-Toggle mode. See below my initialis...
Posted on August 30, 2012 at 14:12Hi, is there a way to detect the SRAM size of a stm32 (F1, connectivity line) at run time? I found a register with the flash size and a so called device identifier (only tells you e.g. connectivity line), but not th...
Posted on August 31, 2012 at 05:51Does Keil UV4 provide step-by-step debug mode? If so, how to activate it? By ''step-by-step'' I mean execute my codes line by line, and I get to observe various registers and ports etc. However the ''run'' button ex...
