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...
Hi,I am using Atollic TrueSTUDIO for STM32 and the STLINK v2 debugger found on most ST dev boards. uC is STM32L476RE if thats needed.I am trying to get semihosting to work for printf. (SDO pin is not available in my project for ITM). I have used semi...
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?
I see that those ITR0 .. 4 are connected somehow to timers you can use it as timer trigger.How do you set it up working. Can somebody provide sample code ?I want faster timer to control (start, stop) with slower time. I have spent a few weeks experim...
Hi everyone,I have a question about ADC trigger. I have to generate a PWM 1.1KHz and read the avarage voltage of ADC pin accoding to the On/Off state of that PWM. How can I make it.? I enclosed an image about it.
