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 ...
Hi, I would like to control a GPS module reset pin thru STM32L152. The reference circuit of the GPS module reset pin as per attached picture. According to the GPS data sheet, the reset pin "Only drive with open collector, no external voltage to be ap...
