Hello! I use CubeMX to generate the init code for rcc whith LSE Crystal NX3215SA-32.768KHZ-EXS00A-MU00525 (32.768K,6PF), two 2.7pF capacitors and rtc module. Program goes to error handler after "if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)"-s...
hello. I am an embedded software engineer from China ,At the moment I'm tryingDrive emmc on stm32l4r5 ,but I failed .Who can give me a demo about how to drive emmc on stm32l4xx , thank you
Posted on January 07, 2016 at 16:29 Hi, I'm developing an IAP application for firmware upgrade over GSM network. I've a SIM800H module connected to STM32 over UART interface and I'm able to establish GSM connection, setup HTTP GET request an...
Hi, I am looking for a way to determine what caused a wakeup from standby mode, in my case the options are RTC or the WKUP pin (and if you have multiple, which pin). In my case I only have one WKUP pin, so I could check the RTC and conclude if it was...
Hello,looking for a STM32 in small package with pins where optical solder inspection is possible, I hoped that the MCU Selector from STCube would offer me a checkbox to select devices with Voltage reference buffer output. I did not find that checkou...
Hi，dear enginner： i want to know how the PC run to startup.s when mcu reset？ The Definitive Guide to the ARM Cortex-M3 says address 0x00000000 is MSP‘，address 0x00000004 is ResetVector. But when I look at STM32F767, I find that 0x00000000 and 0x4 ...
Hi everyone,I want to understand HC-05 working with STM32. But , i cant get any useful document or tutorial that calrify this module. I want to implement a simple application which is remote control of led via HC-05 and STM32F4 disco.Any suggestion p...
Posted on February 08, 2017 at 20:27I use STM32CubeMX to generate STM32F46 discovery board project, just enable 'USBHS internal IP DMA', Choose CDC class, show as the attached picture 01, when I compile and run the firmware, connect the USB HS port...
I have called the three functions as: HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); HAL_GPIO_WritePin(GPIOC, GPIO_PIN_6, GPIO_PIN_SET);when debugging it either jumps to hard fault or hangs.The SystemClock_Config() is as follows:void Syste...
The Keil example 'EXTI project' is a simple program for the STM32F103RBT6 MCU. Here, the following statements are executed:#define __EFI_ACR_Val 0x00000012 /*---------------------------------------------------------------------------- STM32 em...
