When developing I'm using the ST-LINK to transfer my code to the stm32. All is well when it is plugged in but I'm only getting 1v from the 3v3 pin when I disconnect and run from usb. 5v is still 5v.I've connected an hx711 with a load cell and also a ...
Dear all~After I change option byte on stlink, swd (stlink) is not connected.read out protection : level 2 , BOR Level : level 3After not connect. pop upLet me know how to recover option byte. Thanks
Does STM32H743ZI support programming through STLink v2? In Nucleo-h743zi2 STLink v3 is provided.
Hi Team,We are using STM32F103RDT6 MCU, for connecting 5V RS485 transceiver to the MCU. We used (PIN no 16,17) USART2(RX-PA3,TX-PA2)and one GPIO (PIN no 15) pins of MCU. Kindly clarify the below points1. From the datasheet,it shows all pins are 5V to...
I use an STM32F7805-DK and a Keil IDE and have been working well for a month. Suddenly, I get Not a Genuine ST Device. I installed Keil on a second computer and bought a 2nd STM32F7805-DK but get the same result. What can I do... the drivers on the P...
I want to design hardware with STM32G071RBT6 micro-controller, i have basic design circuit but i want to build strong power supply with reverse polarity protection and industrial noise free hardware. please provide me solution for Hardware design.
Hello,I am using STM32F103 for my project and it requires CAN most of the time however if a USB connector is plugged in, it should behave like a virtual COM port. CAN_R and CAN_T pins are connected to PA11 and PA12together with USB_DP and USB_DM pint...
The St_link registers itself and the serial is updated etc. however when I attempt to connect to the newly soldered chip, I get the message that "No STM32 target found".Am I attempting to program this chip incorrectly by using the SWDIO, GND, SWCLK a...
