I have an issue where CDC transmission from an STM32L4 is dropping or duplicating data.Here is a simple test case that runs from main.c extern USBD_HandleTypeDef hUsbDeviceFS; static uint8_t UserTxBufferFS[100]; void TestSerial() { // connect ...
Hi every one! I work with STM32 Nucleo H755ZIQ development board. A dual core MCU with 2MB of flash and 1 MB of Ram. I need to first store data the size of which is around 512KB on Ram and send the data set to a Wifi module. what I need is to see ex...
Hello, I am using a Nucleo-f401re Board and unfortunately I have serious troubles with External Interrupts. I have two inductive sensors which are supplied by 24V. These sensors shall trigger an external Interrupt when the controller detects a rising...
This seems like it should be pretty straight forward but I’m still struggling. I have a project that started from the STM Nucleo413ZH RTC Calendar example. I did set it up in the embedded project wizard as a C++ project. I changed main.c to main.cpp...
STM32F429IGT6 FLASH size is 1M, why can read and write 0x08120000 address data?0x08120,000 is over 1M
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 ...
