STM32L432 Power Problem with NRF24L01 and USART

I made NRF24L01 module using STM32L432. I supplied 3.3V to MCU and NRF24L01. So, I checked USART communication from STM32L432 to PC. But I failed checking SPI to NRF24L01.Below, Problems I have, If I supply 3.3V to MCU(Actually whole module), GPIO Ou...

STM32F407 timer question?

Hi,I am trying to use either TIM13 or TIM14 but the ISR never get trigger.My questions areWhy the ISR routine never trigger? Is there anything else need be set?how to control the timer? what's the prescaler, period mean? If I want setup the timer tri...

Can __HAL_LOCK in stm32 code cause race condition issues

Posted on March 19, 2018 at 10:24The __HAL_LOCK macro is defined as in stm32f1xx_hal_def.h#define __HAL_LOCK(__HANDLE__) \ do{ \ if((__HANDLE__)->Lock == HAL_LOCKED) \ { \ return HAL_BUSY; \ } \ else \ { \ (__HANDLE__)->Lock = HAL_LOCKED; \ } \ }whi...

SysTick_Handler called at 3ms interval instead of 1ms

Platform: STM32F429 Discovery KitI have created a simple project using Keil, to toggle GPIOs. The self generated code sets the clock at 168MHz. When I look at the timing for the SysTick_Handler call, it is 3ms instead of the 1ms that I expected. Why...

STM32L011F4 power consumption

Hi team,i need your help, i use STM32L011F4 controller ,This controller consuming 2mA current in sleep mode, as per datasheet it consumes only a less than 0.5mA current in sleep mode, i can use only a I2C and RTC peripheral with 16MHz frequency.......

HAL_SPI_Transmit uint16_t size limit

Hello,I would like to send a uint32_t size array via HAL_SPI_Transmit / HAL_SPI_Transmit_DMA but both are limited to 16 bit size. I have tried casting as HAL_SPI_Transmit(&hspi1,Array,(uint16_t)65537),10000)but this doesn't work.I have also tried edi...

How do I import a sample project into Eclipse?

How do I import a Cube project? I once managed to set up a project where I am able to write firmware for the stm32f746g-disco board using the tutorial https://www.carminenoviello.com/2015/07/13/started-stm32f746g-disco/ Even after the instructions I ...

Is it necessary to erase startup code(in my case sector 0) before flashing new code into the STM32F723ZE controller.My code failed to run after flashing without erasing startup code.Please help me.
