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...
Hello. I'm a student and need to do some project with STM32L476RG board. One part of the project is to use ArduCam 2 MP. So, i'm looking for a code that i can use.
Hi, I have some problem with UART. I configured two uarts (UART1 and UART2) both of them are working in DMA mode. I want to send data from PC to mcu-UART1 and after receiving it the same data should be sent to UART2. I prepared test env and almost al...
ISR vector table in SRAM works, but not in CCM. Is this possible? If not, what is the theory behind it? Vector fetching done through I-Bus or S-Bus?
