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...
i want use TIM1 CH1 in input capture using DMA.The DMA is set to peripheral to memory and store the data in a buffer of 100 elements.When the transfer of the 100 data is completed i want generate a TIM1 interrupt. Wich kind of interrupt of TIM1 i hav...
Hi community,I'm having a STM32F407VET6 PCB board where VBAT is connected to a 10 uF decoupling capacitor [Instead of recommended 100 nF capacitor].in order to achieve some backup time when both the coin cell and 3.3V are not connected.My RTC is work...
I am using STM32F103C8T6 Blue pill board. When I trying to debug a program.it showing as shown in picture.
In the context of functional safety application, we are wondering the probability of a status bit failure on a STM32H753.A low-level software is frequently polling on status bits of peripherals. If this peripheral encounter a failure this is obvious...
