Hello,to update e,g. PSC before starting a timer, an update event has to be generated. This update event will set UIF and to avoid an interrupt from the update event, the UIF flag needs to be cleared. A sequence TIM1->EGR = TIM_EGR_UG; TI...
Dear all,I am facing to a strange GPIO problem. First af all, I tried to set-up the LPUART1 but impossible to send anything (no activity on PG7 , the Tx of the LPUART1). So, I initialized the PG7 to be a general output and tried to blink it ... no re...
Hi,I use CubeMX for STM32F407VET6.I want to remap CAN1 pins for PB8, PB9, but that configuration initialzing with error.Though CAN1 remap for PD0, PD1 is fine.What does that mean?Thank you very much in advance for your return guys!
Hello guys!I'm working on a custom board with STM32H750VB and a Winbond QuadSPI flash. The ideia is boot the code from QSPI as H750 program memory is a little low. I'm also working with STM32H743VI on a twin custom board, so I can create and debug th...
I coded for usart communication in stm32f103r8.In this i'm getting the garbage value as output.given below is my program,kindly help me to correct my program.****#include "stm32f10x.h"#include "stm32f10x_usart.h"void usartSetup (void);int SendChar ()...
I have a project that involves a STM32F7 controlling a stepper motor through GPIO. I have now been tasked with redesigning it with a ST L6470, a motor control IC which has a SPI interface. I would like have a shared codebase so that a simple #define ...
Hi,How can I power cycle the Nucleo-144 between debug sessions with out unplugging and reinserting the USB cable. Is there a way to toggle PWR_ENn on the STLINK using openOCD and if so could someone please post the script that does this?thank you
My MPU is STM32L152RET6I am using i2c channel 1 to communicate with an i2c device. I used the standard device set and verified the hardware appears to be set up correctly. When I set the "Start" bi in control register 1 (CR1), a start condition is g...
I am currenctly working on STM32L052K6T6. I would like to know if there is an appropriate way to measure precisely the voltage used by the adc. I read through the documentation that this voltage was on adc_channel17 but i have no idea of to get it. I...
Hello,I am trying to switch on pwm for 10 ms timer and then switch off pwm and use those pins as gpio (high and low) also for 10 ms. This whole process will work in loop.We even tried to set idle state of pins as set and reset in cubemx but as we sto...
