Hi, I have encountered strange problem where my code does not work properly on STM32F405RG when there is recommended 100nF cap between NRST and GND pins.By "working correctly" I mean receiving correct message from USART. I am sending 0xAA and getting...
I followed the steps of the example: I flashed the microcontroller L152RE of Nucleo with cable USB CN2 and then I connected the usb cable, I chose the .dfu application in binary folder, I did the upgrade and then I pressed reset, I don't see the LD...
Hello, can we expand or use external RAM with stm32h743vit6? Could anyone guide me for the same?
We are building a board using STM32H750VB and I need to connect a USB connector. I thought of using OTG_HS. In this type many signals related to ULPI and OTG_HS_SOF are available, which I don't need. So I need to know whether these signal are mandato...
As per UM2407, page 42, PC8 and PC9 should be Pins 1 and 2 of the CN12 Morpho connector. On the silk screen on the board the corresponding pins are labeled accordingly as well.However on my NUCLEO-H743ZI2 board I can not get a signal from the MCU on ...
I am using STM32L152VE microcontroller and I am trying to blink an LED using external interrupts. The interrupt works fine in all the ports except port F and G does anybody have any idea as to why this might happen?Thanks in advance
Hi all,I'm using STM32f405 and i want to program FLASH using STM32CubeIDE.My testing code is the following: uint32_t base = 0x080E0000; //FLASH SECTOR 11 uint64_t data= 0x55; FLASH_EraseInitTypeDef EraseInitStruct; uint32_t Error; EraseInitStr...
Hi,I am writing code for the STM32f103 involving ADC conversion.I understand you have to select a list of "channels" you want to be converted and put them either in a regular or injected list. These lists are contained in the ADC_SQRx (or ADC_JSQR fo...
Decorated memory store and load for atomic operations
I am having a problem where the IWDG seems to not reset the processor. I have setup a very simple project that enables the IWDG and then doesn't pet it - it should reset, but it doesn't. Running under the debugger or running standalone, it doesn't re...
