Posted on August 20, 2015 at 15:26Hi ,Please i have to measure frequency from 1Hz to 3Khz with timer 1 (16bits)My SysTick clk = 72Mhz, so i set the prescalor to (1000-1) .So i have a Counter Clock=72Kand than i can capture frequency starting from 1H...
Posted on January 06, 2014 at 15:50 how he calculate this So, we will have the following FSMC timings: ? Address setup time: 0x1 ? Address hold time: 0x0 ? Data setup time: 0x5 #too-vague
Posted on August 20, 2015 at 06:42Hello! I trying to create an aplication with FFT. So, I read 1024 points from internal ADC (12 bit), sampling frequency 1024 Hz. Then I process them with FFT functions from DSP lib STM32Cube_FW_F4_V1.7.0.http://code...
Posted on August 21, 2015 at 00:28 NOTE: edited by moderator on Oct 6th, 2016 Hello everyone, I just received my stm32f4 discovery board yesterday and it works well :). I managed to run a LED blinking example. I now want to display ...
Posted on August 23, 2015 at 17:32Hello,I'm trying to program an external prototype board that I made using the same MCU as on the Discovery (stm32f407VG) and am getting the following error:Error: Flash driver function execute timeout Erase: ...
Posted on August 22, 2015 at 16:10I was developing a system on the Nucleo board. I then moved it to a custom proto PCB which I was programming from the Nucleo on-board ST Link. Everything was great up to that point. When I reverted back to use the...
Posted on August 23, 2015 at 16:41HiDo anybody know how to rotate the screen when using stemwin ...Did try with GUI_Init();GUI_SetOrientation(GUI_MIRROR_X |GUI_MIRROR_Y);GUI_Exec();but it did not work ...i tryed to look in lcd_conf but could not get...
Posted on August 22, 2015 at 21:36hi folks, i've a soft spot for the STM32 series after managing to make a USB audio device a couple of years ago, using a lowly STM32F103. so for a new project i am delighted to find that the price has reduced consi...
Posted on August 16, 2015 at 20:22Hello, I try to send a message out via uart, every time I press a button. The init of uart works, because there I send the first message, but if I would do that in the main it brakes every time in the HAL_GPIO_INIT(...
Posted on August 23, 2015 at 10:47Hi guys,i'm try to understand can bus configuration. I need to know if what is in my mind is correct.I'm using a STM32F4 discovery with the CAN1 configured on pin PD0 and PD1.I see on the forum that the CAN frequenc...
