Posted on September 01, 2012 at 14:33Hello, i want to boost DFT speed so i need to calculate lot of sinf cosf and store in external SRAM. internal is capable only for few dft points in spectrum, so i have to store them into SRAM, but don't know how...
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 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 30, 2012 at 07:36Hi,I need an accurate hardware independent Dealy function for stm32l152rbt6 controller, the delay should be completely relay on the software. #silly-silly-silly-questions #!rocketscience #sloppy-thinking #hardwar...
Posted on August 30, 2012 at 20:28Hi Please help me with synching 4 timersI need 4 PWM from 4 different timers to sync it's output so that i get this result: ________________ ________________ _| |____________| |___________ TIM9_CH1 ________________...
Posted on August 25, 2012 at 17:16hi , i want to build a stm32 jtag programmer . i find lpt jtag circuit . but i can't find software. why this forum-> *bad interface *not friendly interface #credit-where-it's-due #lmgtfy #no-such-thing-as-a-fr...
