I could really need some help how to get a STM32F030T4P6 to act as a i2c slave and receive a byte of data I've spend so much time in the past week trying to solve this problem, but no progress at all The final code must act as four PCF8574 port expan...
Hello.An inexplicable bug occurs during the transition from startup_stm32h743xx.s to main, causing unnecessary functions to be repeatedly executed.An unknown function (I2C_IsErrorOccurred) continues to be called. It is strange that it is being invoke...
I'm working on getting the STM32G0 to stop mode. Im using WFI so it will wake on interrupt. Right now its immediately waking which is confusing me.My understanding is that I should __disable_irq() first to prevent the interrupt handlers from being ca...
Hi,I am using a STM32F446 as a USB high speed host. my device is connected to a USB3300 chip to control the micro usb port, which is then connected to a camera. My code works ~90% of the time, however sometimes the connection to the camera can be unr...
Hi all,I am using customized designed board consisting of stm32G4CEU microcontroller and we have USB connector to do the data communication with the stm32 microcontroller. Once I connect the USB to my PC (Windows11 Pro) then its not getting recognise...
Hello Community,Is there a way to inject double Flash ECC Error in Stm32L5/U5 like it is possible in case of H7 where we can simply write some different set of words at a given address without erasing? Thanks in advance,Abhi
Heyho,I'm currently using a GPIO on a STM32L031 for a custom 1-wire interface, which means it's switching all the time between input and output mode (open drain).So far I have learned that the EXTI interrupt only works with GPIOs in input mode.My que...
Hello, I have been trying for some days to read the values incoming form both ADCs, ADC1 & ADC4, from the NUCLEO U545-REQ. The overall idea is to trigger both ADCs at the same time in output compare mode but if i try to trigger both of them at the s...
Hello everyone, I'm currently trying to set up the two ADCs (ADC1, ADC4) on my NUCLEO-U545RE-Q for multi-channel continuous conversion via GPDMA (I've previously used an L4+, but intend to change to the U5 family for the final product and am using t...
We want to trigger two conversions from the same EXTI (EXTI11).Basically rising edge on GPIO B11 should trigger ADC12 conversion and MDF (sigmadelta) Is it possible?
