I am trying to use RTC to wake up my stop mode every 30 second. I have two questions:so every time when RTC wakes up, I use below code to HAL_RTC_DeInit(&hrtc);:MX_RTC_Init( true ); to reinit RTC, and I don't use the interrupt handler.It appears work...
Hello,I am a newbie and I have started trying to learn how to program the MCU STM32F746ZG. I have created a simple code following a learning book that uses the STM32CubeMX software. The code is a simple "Hello World" that causes LED2 to flash every 5...
Hello, One specification of my system is the long live of my peripheral (Nucleo-L152RE+ IDB05A1). The most time, my peripheral is in advertising mode. I know that as soon as IDB05A1 advertising I can put µc in standby, the IDB05A1 will work autonomou...
HiI want to start using the MPU on STM32F7, however when I enable the MPU then unaligned accesses lead to a HardFault immediately.Code to reproduce the HardFault:static unsigned short foo[5] = { 0 }; memcpy(&foo[1], &foo[3], 4);I wrote a minimal Hard...
Hi, I'm trying to add the Printer class to a project with a USB host port.Is there any code available?The project was created with CUBE-MX and uses FreeRTOS.
Hello there,I am working on STM32L432KB's Power saving modes and currently testing STOP2 Mode.After reading reference manual I made the code below to Enter and Exit from STOP2 Mode.My Goal is to enter Stop2 mode when a button is pressed and get back ...
STM32F030F4 MCU. I import the variables, I want to see, in the STMStudio. Imported well. But the value of the variable is always displayed zero. Does this MCU support STMStudio? I have: ST-Link/V2 original. SWD protocol.If the MCU is supported, then ...
i'm trying to transmit distance measurement data recorded from the vl53l1 sensor to a caspian module in order to drive a liquid lens. And for that i'm using an i2c bus: i2c1 to collect measurements data from the sensor and i2c3 to communicate with a ...
I fabricated the PCB by combining STM32F769BI + IS42S32800D-6TLI SDRAM.The circuit only changed the package type, and the circuit of the 769-EVAL board remained the same.The firmware did the same.However, SDRAM does not seem to work at all.SDRAM init...
Posted on June 05, 2015 at 01:56Hi,I have a STM32F4 Discovery + DM-STF4BB and I want to try lwIP on it. I have SW4STM32 installed and I am trying to create a new project through the wizard, using STM32Cube HAL, and lwIP, with and without FreeRTOS.I ...
