I am using STM32F302R6T6 MCU. I'm making a board. I will communicate with the MCUs via the I2C protocol. I am designing a card with a Master-Slave structure. Can I program the MCU if I add SDA, SCL, +5V, and GND pins to the board and connect them to ...
I am currently implementing a Profinet protocol on the STM32H743 which needs VLAN information in some packet types. Since the VLAN tags are already generated by the software for transmit packets I tried to get these tags passed through the Ethernet M...
Hi thereI bought two Nucleo-H755ZI-Q (NUH755ZIQ$AT3) boards.Non of them show up as USB devices on either of my computers.I have tried connecting through the IDE 1.13.1; STLinkUpgrade 3.12.3 and the newest cubeprogrammer. neither can find the device....
Dear STM community,We are using a STM32H745 microcontroller interface with 1280 x800 TFT lvds display.RGB data from controller LTDC data convert through SN75LVDS83 ic and LVDS data fed to tft display.we are facing a issue in pixel format which is not...
Where can I find an svd file for the STM32L4P5 with a full definition for TIM15?Everything I've found is missing Channel 2 definitions.Thanks,-Rob
Hi,I been trying to set up a stm32F405 mcu usb host with a hub onto which 4x stm32 device is connected. I would use these 4 devices to send data to the main mcu periodicaly at 50Hz, and to have the data transfer syncronised from the 4 devices to be o...
We are working with STM32H7-Disco (Dual Core). Can we only wakeup M4 core and put the system in dstandby1 mode.I mean, if we are in Standby mode and we use a tamper interrupt from a button, our system reset M7 core and M4 core, but we want only wakeu...
Hi,This is my first post by the way, I do have stm32f401 and I am trying to use the stand by mode , I want to detect the wakeup reason, is it RTC or reset button, in case of RTC I will do one thing and incase of reset button I will do something else,...
So, I'm having strange behavior regarding the serial number of my board with an STM32F091.I have a Python software that sends a packet on the serial port every 100 ms. I have initialized the serial port on the ucontroller with the same settings as ar...
Even Arduino boards have schematics available, why is ST doing this? Do you want to wipe out the few users who buy the development boards? :thinking_face:
