STM32 MCUs Products

I'm new to arm,so forgive me for asking this question. I wrote a program to display text and integers and FLOATS on a LCD. I just can't display the floats.I tried sprintf and printf to no avail. Please help solve this issue.Thanks.

Is there any way to accumulate (summation/integration) ADC results using DMA or similar?

I am collecting a stream of ADC samples that are being integrated (added together and multiplied by the time period) at regular intervals during an ISR but was hoping there may be a way to offload this so I could just read and reset the accumulated v...

Changing PWM during runtime using timers

Went through examples of Nucleo -L073RZ eval board for PWM outputIt generates four PWM waves using Timer 2 channel 1 ,channel2 ,channel 3,channel 4at 50%,25%,12.5.37.5% duty cycle . So the pwm duty cycle is fixed.but i have a fan pwm connected to T...

Currently im working on STM32F103R8 and im trying to create delay using TIM3 ,the following is my code but i didnt get perfect output.Please someone kindly help me to overcome from this.

#include "stm32f10x.h"void init();void Timer_delay();void main(){ init(); Timer_delay(); while(1) {  while(TIM3->SR & 0x0001)/*Check the TIM3 update interrupt occurs or not*/  TIM3->SR = 0x0000;/*Remove TIMx update interrupt flag */   GPIOA->BSRR^=0X...

Receiving data from USART

I am trying to use asynchronous USART on stm32L4R5ZI nucleo board for sending and receiving data. Following is related part of code.while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); //Toggle LED HAL_Delay(1000); //Delay 1 Seconds for(...

How can I identify which STM32F0x0 parts have two or more general purpose timers?

 I need two quadrature encoder input pairs. The standard ST selection matrix only includes the number of 16-bit and 32-bit timers.

USART_SendBreak not available on STM32F373

Hi,I have to configure a STM32F373 as a LIN Master. The problem is that the function USART_SendBreak is not available.The reference manual says that I have to set the SBKRQ bit to send the break frame, but this bit is only available for a break reque...

OSPI readonly in memory mapped mode

I use the STM32L4R9I-EVAL Board and try to configure the ospi on nor-flash for readonly in memory mapped mode. there is an example projekt in Hal-Lib L4 V1.14.0. If i skip the erase and write steps, it read out wrong values (with out hal error)!Do an...

STM32F7 SDMMC ignores eMMC's response to READ_SINGLE_BLOCK

MCU: STM32F777Cube: 4.25.0FW: v1.11.0I'm seeing cases where the F7's SDMMC isn't setting any of the required Status Register bits as the result ofan R1 response to a READ_SINGLE_BLOCK command after having previously handled up to tens of thousands of...

SPI interface between STM32L151QD and External Flash

Hi AllCan anyone suggest the example code for Spi interfacing between STM32L151QD and External flash memory.,Through my STM32L151QD I want to read and write from External flash memory , The both STM32 and Flash memory is connected with SPI interface
