I'm trying to do something similar to what have been covered by the application note AN4666 "Parallel synchronous transmission using GPIO and DMA" but now I'm testing without DMA functionality. Right now, I can write/send data to GPIO port using: GPI...
I've complained about this before, but it is still broken and shows lack of grasp.STM32Cube_FW_L4_V1.13.0\Projects\NUCLEO-L432KC\Examples\RTC\RTC_LSI\Src\main.cThe following code results in answers which are a multiple of 8, and loses precision which...
chip : stm32L433CCUX. source code is made by cubeMX automatically.below my scenarios.1.stm32l4 starts with uart baud rate 9600. and start with uart DMA.2.communicate with other gps module by uart baud rate is 9600. for gps configuration gps uart ba...
Hello, i use RTC to exit STOP1 mode (tick disable) , the only way is to call HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFE);HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFI); doesn't work.Have you any idea why ?thanksregards
I have checked for Input Capture Indirect Mode, however I couldn't understand what and how about it. I have read the Timer Cookbook provided by ST in detail and it talks about Input Capture mode. I have programmed my STMF446ZE Nucleo board to read in...
Posted on May 07, 2018 at 17:15Hello, I am new in stm32. I am trying to configure timer. I don't understand input capture indirect mode. Does anybody know how to use it? I am trying TIM3, I found channel 3 can be input capture indirect mode.thanks.
Hi,Looking at http://ww1.microchip.com/downloads/en/appnotes/00687c.pdfto implement a RTD temperature sensor and the onboard ADC on the STM32F334, trying to get the ADC Vref out to the constant current generator opamp. I can use an external Vref for ...
HelloI installed CubeMX. It works but the font of the editor is so tiny that it is not possible to use it. How to enlarge the font of the CubeMX Editor?
Hello:Using IAR EWARM 7.8 for these tests. IAR provides working HAL examples for the STM32F4 Discovery boards. They have a specific example for both input capture, and PWM capture on the STM32F4 Discovery. Both examples work....both capture a 2KHz sq...
Dear ST Community,The MCU type is: STM32F407VGT6I try to write GPIOx->ODR register with DMA2. The trigger signal is TIM1 update event. I set the timer period frequency is 9Mhz and i measure 4.429Mhz on GPIO pin. Why?here is my code:#include "stm32f4x...
