Hello together,I just tried to get my STM32F407-Discovery working. I wanted to upload the firmware by putting it into DFU Mode, connecting it via USB to my computer and using CubeProgrammer to upload the code into the STM32s memory. So I connected BO...
Hello everyone!I have a problem regarding my STM32F072 MCU board that I designed: I cannot connect the board with a terminal properly. Let me explain:1. I've managed the program the board using ST-LINK V2 (Chinese version) and SWD pins.2. When I conn...
I am designing a self-powered device with an STM32G473 and a USB-C connector, and want to be certain about the connections.I have made PCBs with USB-C connectors before, but this is the first time that I have neither a VDDUSB, nor a VBUS Sense input....
Hello, I'm currently trying to receive some data from device #2 (legacy device, not a PC) with my uC STM32 (device #1). But in order to receive the data I need to generate a pulse in the DTR pin or CTS (both are connected in the device #2) on the con...
Does the STM32L072VBT6 or STM32F072VBT6 not allow for the USB connection to function, even when VDD is OFF?
Currently using Nucleo-H7A3ZI-Q to test the USB FS interface and using Cube FW 1.10.1 -Using Nucleo end as USB Device mode with CDC class. The schematics of the nucleo board tells me both the VDD50USB and VDD33USB is internally self powered and tied ...
Hello,I got a stlm32 disco board. I cannot Flash.So,I used STM32 ST-LINK UTILITY. Any connection fail even under reset. This one show Target Voltage Detection Fail. The board is powered by the USB CN2 Connector. The measurment on the CN4 Connector sh...
as with the stlink mods your limited to a 5v out at 200ma and if the usb was broke out i could use a usb c connector on a pcb and have alot more voltage options
I have setup the STlink to communicate to TeraTerm to use printf/scanf. This works at the default clk (4MHz) and 115200 Baud. This does not work at any other sysclk freq or baud rate. I have verified the clk setup and usart setup & communications usi...
