STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
While stm32l4r and stm32h7 have DMA1MUXEN and DMAMUX1RST in the RCC register space, I see no such definitions in STM32G0. Are these definitions missing in the headers or is there really no such functionality in STM32G0
In Single SPI mode, the unused qspi pins are held as follows: IO2 is in output mode and forced to ‘0’ (to deactivate the “write protect�? function) IO3 is in output mode and forced to ‘1’ (to deactivate the “hold�? function)Problem is, all the flash ...
Hi all,I do have a problem with I2C slave transmit mode. Everytime the master (in my case an FTDI FT4222) starts a read access I get the error ACKNOLEDGE FAILURE.If I just transmit from a PC to the STM32 everything works fine and I receive the correc...
Hi,I want to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon receiving a trigger signal on the timer capture input channel TIM1_CHI (PE9) . I am using stm32f446ze.We nees to acquire data regi...
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 ...
