Hi everyone,I’m testing a 32Mb serial QUAD SPI RAM (ISSI – ISS66WVS4M8) with the nucleo – H723ZG development board.It works fine if I use all the QUAD SPI commands but my need is to use it in memory mapped mode.When i use the memory mapped mode confi...
Hello, I have a DMA stream working in Normal mode (Mem to Peripheral). This by itself is working properly (without MDMA). I want to configure MDMA to set the next parameters for the DMA to handle. I configure 4 words (4 uint_32) in memory for writing...
Hi, I wanted to clock my timer output using LSE crystal, but unfortunately only tim2 is supported with this feature. But then I saw an option of LSCO as output in cubemx, this enables the pin on MCU and according to documentation this output LSE cloc...
Hello,I am currently developing a Bootloader for a STM32H562. The Bootloader checks, if there is a valid application present by calculating a checksum over the application area. To avoid getting ECC errors during the checksum calculation, I disable t...
Those are the setting for STM32H7A3IIT6Q ? (there is AN5050 where they show but DMA setting only)I am trying to useHAL_OSPI_Transmit_DMA(&hospi2, aTxBuffer)(I have this chip working in interrupt mode fine , HAL_OSPI_Transmit_IT(&hospi2, aTxBuffer) b...
Heyho,I'm currently working on an ethernet bootloader, I have it all working now.File upload via browser using http POST, into HyperRAM (~200 ms for 400kB bin file),from HyperRAM to external SPI flash (for now octal on H735-Discovery, later changed t...
Hi everyone i got this error when i try to use hal_delay functionhttps://community.st.com/t5/stm32cubemx-mcus/stm32cubeide-1-7-mcu-package-l4-series-1-17-vtor-is-not/m-p/220563 I applied this solution it works now but the real time passed is the doub...
My only need is to use QSPI (dual mode bank1) as a simple/normal SPI to drive external DAC (AD5066). I should only use the Data phase, I don't need the Instruction, Address, Alt and Dummy phases of the QSPI.I have to use:QUADSPI_CLK---> DAC_CLKQUADS...
Hello, does anyone have any simple code for interfacing a digital microphone with the Serial audio interface? The MEMSMIC1 example project seems too complicated to start with. I am using the stmwb55rg nucleo board
Hello,I am using a STM32H743 with a W25Q128 external flash memory running FreeRTOS and FatFs. USB is configured for mass storage, to copy files from a computer to the flash memory. The following function is used to list all the files and directories ...
