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...
when we are doing Signal integrity for STM32h743BIT6 with the IBIS model provided by you is not giving proper output,where as for STM32F7 series IBIS model are working good.so can you help us by providing any another IBIS model or any suggestions for...
Hi Guys i am trying to get the data from lidar which works on UART and i am using interrupt to get the data value but i am not getting the acc to datasheet of lidar i am using HAL_UART_Receive_IT(UART_HandleTypeDef *huart, uint8_t *pData, uint16_t Si...
I want to charge the Android phone along with USB data transfer. I am using STM32F072C8T6 as micro-controller and NCP1855 for mobile charging.The problem is this, in some mobile phones the charging is happening but the USB is not getting detected(And...
