Hi,I have asked this question before, but this time with a different aspect.Board support for STM3240G-EVAL board was available in Keil V4. In Keil V5, it's not available. Is there any way that I can copy some files from V4 installation to V5 install...
I am working on a very power sensitive application involving a STML431 processor running only off a battery. I plan on using Shutdown mode most of the time with an hourly wake up. I am looking for 1 measurement (maybe averaging a few actual samples)...
Hello,I'm having some trouble using the timer based interrupts.I have some very basic experience in mcu programing but I'm new to the STM32 platform and I had to adapt to it rather quickly. Therefore I lack some of the basic knowledge.My first questi...
I have been trying to perform SPI communication and observe outgoing and incoming data through MOSI & MISO. There is a weird problem in SCK weveform There are the codes I wrote :#include "stm32f10x.h" #include "stm32f10x_rcc.h" #include "stm32f10x_gp...
Hello, I'm designing a PCB with an interface to an existing STM32769 board. I would like to use one of the STM32 timer inputs to trigger a timer. When the timer reaches its "compare" value it should trigger a DMA request for an SPI transaction. Accor...
Hi,I am starting to program STM32 devices and I have an STM32F745 chip. Since I want to learn all the details I'm programming it from scratch, using only the definitions from CMSIS.I have a very simple program where I have 2 LEDs on PB6 and PB7 respe...
i made this code to blink an led with systick time but it does not work can you please correct this. i am using stm32l152rc discovery board. #include "stm32l1xx.h"while { if (SysTick->CTRL |= SysTick_CTRL_COUNTFLAG == 0) { GPIOB->BSRRH |= GPIO_...
Posted on May 01, 2018 at 16:12 I am trying to use CFFT function for my STM32 microcontroller in Atollic TrueStudio. But I am unable to use any of the DSP functions. I get the error - undefined reference to `arm_cfft_f32' and undefined refe...
Hi all,I am unable to wake up my mcu from standby mode using any of the wake up pins. Below is my code. Any help is appreciated.Thanks. :grinning_face_with_sweat: /* Private function prototypes -----------------------------------------------*/ void...
Hi,I am using STM32F051R8T6 (of Discovery board). In my application I am using two timers: TIMER3 and TIMER15. TIMER3 is used to count number of pulses. Hence, I have used it as an external clock source based timer.TIMER15( based on internal clock so...
