Hi,I am working with STM32H753 and I am developing baremetal application using FMC. The FMC is interfaced with an external asynchronous memory, address and data signals are not muxed and there is no need for NWAIT, NADV nor CLK signals.On the FMC sid...
Hello everybody,I am quite new from working with STM32 products but recently made the switch from Atmel chips (thanks to the free handout of Nucleo boards at the Eurobot competition I guess :) ). I recently designed a fairly simple board, centered ar...
I am using Nucleo STM32 L432KC board with STM32CubeIDE v1.12.1 and doing very basic DSP operations with data values read via ADC through DMA into a circular buffer. It works, but the math is slower than expected.Below is an example loop in my code. A...
Hello,I am moving code from one MCU to this old STM32L152 in where the UART is configured as Multiprocessor Mode.I am using STM32 CubeIDEI get compile error.. It looks to me like there is no WakeupCallback at all. HAL_UARTEx_WakeupCallbackHAL_UART_...
I am trying to do disk i/o with a FAT32-formatted SD card (32GB ADATA) using SPI on a STM32H742VIT6.The disk_initialize() function in diskio.c does not complete because it looks like the wait_ready() function is always timing out.static int wait_read...
In datasheet for STM32U5Axx is mentioned:a) "up to 14 I/Os with independent supply down to 1.08 V" - cool, great feature I needb) OCTOSPIM: "efficient OCTOSPI pin assignment with a full I/O matrix (before alternate function map)"What does it mean?Cou...
Hi all,I am using a STM32H723ZG Nucleo-144 board. Here I have attached a micro-SD card module. I am sampling from one of the ADCs with 8.33 Msps at 8-bit resolution. I am able to transfer the data to RAM using DMA without any loss. However, I wonder ...
First bug, i start testing CEC on F051DISCO . Open MX create config for KEIL v5 and generate code.After build and load i spent some hours to locate why code dont receive and hangs. Elaborate bad generated startus assembler file where is IRQ named CEC...
Hello community,I cant get the dma working on the stm32g474. What I did till now:- enabled tim15 -> working with interrupts- enabled dma req. on update event- enabled dma and dmamux clocks in rcc- enabled dma int in nvic -> can be triggered through n...
Hi , I am using STM32L072CZT6 for our low power application. We are using Standby mode with RTC for alarm and periodic interrupt wakeup. The device is wakeup and work properly for more than 12 hours hours. After that the controller didn't operate and...
