Hi all,I configured RTC and standby to wake up after 5 seconds, once standby is entered. This works fine after flashing the program. But once waken up from standby, if going to standby again, the device returns from standby immediately.Beside the RTC...
I am working with a project which does not have .ioc file from STM32 cube mx, so I have to enable HAL functions and make these changes manually. I wanted to add a watchdog timer. Somehow the Drivers/STM32L4xx_HAL_Driver/Src/stm32l4xx_hal_wwdg.c file...
Hi, I am using STM32F030R8T6 nucleo board, currently working in a project that require stand by mode, and I am also planning to wake-up using RTC ALARM, while I set alarm and enter into stand by mode it wakes up at the alarm, but it does not enter t...
The ref manual (RM0481 page 2585) says: "This circuit has a defined startup time (tSTARTUP specified in the datasheet) during which the behavior of the USB transceiver is not defined.". I searched for USB and tSTARTUP but could not find anything in t...
Hi,We are using STM32H745XI processor for one of our customer products. To start our initial software prototype development, we are looking for the evaluation kit. I went through the processor product page, and I have following queries:1. Looks like ...
Hello. I'm using STM32F745VET.I want to connect SRAM via FMC, but when I run a simple app, the waveform look like below.The code I made is just write data "0x28". and It does not work.As you see, NWE signal work high-low periodically. I think this is...
Hello,I found an example on the internet of a project but I don't understand the usefulness of using a Timer 7. Could you tell me why ? Thanks in advance. __IO uint32_t usTick; void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { /* Preven...
Hi I have my own board with a STM32L433 , running on a battery. I place the processor in Standby mode, then exit it with the RTC AlarmA and periodic timer. As soon as it wakes up I initialize the uart and display a message on the terminal .When put ...
I'm trying to prototype an audio effects unit with the STM32H735G-DK board. I am using the line-in input jack and output (headphone/line-out) jack. There was no example using the line-in jack for the 35G-DK board as far as I could find. So I just ref...
Posted on March 26, 2017 at 23:53I'm using CubeMX 4.19.0 for STM32F407G-DISC1 and firmware for STM32F4 version 1.14.0. (yes I realize there is an update).When setting up an SPI port, one of the parameters is CPHA, the clock phasing. You have to decl...
