Dear,I use SM32L152, I go to STOP mode regularly and as the possible source of waking up is either RTC or External interrupt. It works Fine until I change the System clocks from MSI 4 MHz to for example HSI on 16 MHz. If I change it, then MY MCU is w...
Posted on August 28, 2014 at 12:45I am using timer1 channel 1 as output compare, to generate a pulse of variable period.Desire output � In the beginning the output remain low for 4 ms(delay period) and then pulses of variable periods as 5.8, 3.6, ...
Hi all, I would like to know whether the write access to external flash is possible when the code execution is from external flash? When I tried to write on external flash HAL function returns driver busy, since it's been used in memory mapped mode f...
Posted on February 14, 2018 at 01:55Hello,I have a program using serial UART communicatons. I based the UART code on the example code UART_TwoBoards_ComDMA. The system seems to work correctly when it is in command/response mode. That means, I can ...
I'm new to working with STM32's so if I make any mistakes please let me know. I have the STM32F446RE Nucleo board and I'm trying to read two ADC channels (IN15 on GPIOC_05 and IN14 on GPIOC_04) and output the ADC values over USART 1 channel as fast ...
I am working with the STM32F769NIH6 microcontroller and it's communicating with a different processor using a home-made SPI-based protocol where the STM32F769NIH6 is the slave. The master clocks data at 11 MHz and the STM32F769NIH6 is running at 120 ...
Hi,I am working on a custom device, based on Murata CMWX1ZZABZ, running both Sigfox and LoRa.Regarding Sigfox, I would like to use my own Sigfox Credentials, acquired direclty from Sigfox (not from Murata). However, the only documented process I can...
Hello, I'm using the STM32746G Discovery Board to familiarize myself with the ST environment. Now I simply wanted to store a 32Bit value in the RAM, and had several problems with the Cube BSP drivers. I tested the functions with the following code: #...
Dear all,I have a board with only the STM32F765VIT6 and I program through the stlink with a power supply of 3.3V (.At start of program i tried HAL_PWR_EnterSTANDBYMode() to get 3.5uA with success if before i disable overdrive with HAL_PWREx_DisableOv...
Hello,I wonder if I use the internal pullup resistor on an STM32F4 on an open-drain output, if the MCU is reset with the line NVIC_SystemReset(), does the internal pullup resistor with open drain output will still be seen by another IC connected to t...
