HiI just wonder at the example:STM32Cube_FW_F4_V1.26.0/Projects/STM32469I-Discovery/Examples/FMC/FMC_SDRAM/Src/main.cand there is a define:#define WRITE_READ_ADDR ((uint32_t)0x0800)Whats the purpose of that (offset?)? Doesn't the FMC SDRAM start ...
Hi Experts,I need to run my code (it is a small code) from internal RAM. It currently runs from the first sector in the flash. For some reason, I need to change a few bytes in the same sector and it seems I can't write to the same sector from where t...
I am trying to work on an acoustic system but unfortunately the system is not responding as it should and i have connected all the equipment.Kindly see attached for reference.Thank you.
Hi all,I'm trying to manage a long pression on a Flex button.I want realize this simple algorithm:short pression = action_1()long pression(IE 2secons) = action_2()I enabled clickListener over this Flex button, I configured the trigger event on "Touch...
AN4221 says it will enter I2C boot mode on detecting its address and will then start waiting for commands. What is not clear is whether this address is sent as part of the first command, or by some separate undescribed operation. I've tried various a...
I want that the user can design the screen at runtime. So I'm trying to add box, text, image to the screen by the user button. I tested font caching for the text and didn't know how to add the text and where it should be. Even the text is cached, ho...
So we have just gone into production on a new design, a very small part of the circuit monitors the devices battery voltage fed into one of the ADC channels. I am finding that 1 in every 50 boards has developed a failure with the ADC where it just re...

Dear ST Community,I would like to set up the USART1 and DMA2 in a way, so that the DMA automatically stores the data received by the USART to a buffer variable.To achieve that I used STM32CubeMX to generate the configuration code utilizing the Low Le...
