Posted on March 15, 2018 at 11:03Hello there, Using the BSP example code I have composed a function for reading data from an external QSPI flash memory. Here it is: https://pastebin.com/ZsGjfDGD I am facing a peculiar problem at the moment. When I r...
I wanna my design can back to working after EMC shocks.So I plan to use Hardware watchdog , with followed code under ucOS*************************** usrOption = FLASH_GetUserOptionByte(); if( (usrOption&OB_IWDG_SW) != 0) { FLASH_Unlock(); FLASH_Er...
I am using an STM32F429FI Nucleo board, and not able to communicate over UART with the confiiguration having 0.5 Stop bits and DMA being enabled.Is this a valid configuration? Data sheet suggests use of 0.5 Stop bits with SmartCard mode does it mean ...
Hi,I'm using STM32F722RET, and I'm trying to do ADC sampling of 3 channels using DMA with a timer trigger.I configured the following:ADC:hadc1.Instance = ADC1; hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE; hadc1.Init.ContinuousConvMode = ENABLE; hadc1.I...
Posted on May 12, 2015 at 01:12 So in `SD_PowerON` there is a comment at the bottom that says `/* else MMC Card */`. `hsd->CardType` is never set to `MULTIMEDIA_CARD` which is defined in `stm32f4xx_hal_sd.h`, and read in `HAL_SD_WideBusOperation_Co...
Hi can i use the same uart as my JTAG debugger uses to communicate with my Lidar i am using nucleo-64 board.It is uses pins PA2 and PA3 to load the program?
Hey everyone,I am outputting a waveform via TIM2 CCR1 stored in an array and transferred via circular DMA access.The timer is configured for output compare so that whenever a match occurs, a dma request is generated and the next value is fetched from...
The Nucleo Board takes clock (8MHz) from ST- Link Programmer and we want to switch it to external (8MHz) crystal which is not working.We programmed the RCC->CR register to 0X03030300U so that it sets to external crystal but it shows 0X03050305U ( HSE...
Hello Everyone,I am using STM32H753I-EVAL board and I am using on board SDRAM for all my data storage and computations (which includes floating point calculations). I am able to run SDRAM at 100Mhz. Even though my controller is running at 400Mhz ther...
Have some problem with my code. CLock works too fast(about 20%). no difference between built-in oscillator, or crystal. And counts wrong(1, 2, 3...9, 16, then again 9 normal, and jump 6 up).Heres my code:#include "main.h"#include "an_disp.h"#include ...
