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 ...
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...
