I am experimenting with the USB HS peripheral on the STM32U5A9NJ Discovery Kit, and noticed that there is a signal called VBUS_SENSE which is routed to PG1 (ADC4 IN8). I've configured ADC4 to sample from this pin, and notice that the sensed voltage i...
Hi,i made up this circuit, to protect the input of the MCU. The switches pull to GND with 0 Ohm to 22kOhm, and this is also where the ESD would come in. The output_line also goes to a MCU input, and its the one i am not sure, if its protection is eno...
https://drive.google.com/file/d/1r9MhSFT5c7hjDf6kfRWHOomkzLH9iJMF/view?usp=drivesdk Hi Everyone I made a custom board keeping stm32f429 disc1 board as a reference.When I connect the the board through usb mini it's showing USB not recognised. Below is...
Hello ST Community,I am encountering a clock configuration issue that I need assistance with.I initially began with a blank template using an internal clock, and the code ran without any problems. However, when I attempted to configure a 24MHz extern...
HelIo,I connected the anode from a diode to the operating voltage and the cathode to a pinx. I need ground to make the diode glow. How can this be implemented?
Hello community!I set up a dmamux channel, which is working perfectly in unconditional mode(direct mux). Now I want to use synchronous mode, where the EXTI0 line Interrupt is the trigger(or latch), so it initiates the DMA request transactions. I get ...
I want to install and run GRBL firmware in STM32 nucleo-F401RE board to make CNC machine where stepper motors would be driven by CNC shield.
Hi! Just as a comment, did anyone had that kind of problem?uC is not found or easily losing connection while erase/program.Everything is properly designed and soldered (even programmer pins are temp. soldered to board).Every connection was checked an...
I have an Arduino Giga (STM32H7), and I'm trying to generate PWM's. I succeeded using alternate function AF9 of PA7 (digital pin 5), which uses TIM14_CH1. Now, using the exact same code (as far as I can see) but using PA2/PA3 (digital pins 3 and 2) a...
When you look at your Nucleo-f207zg board, ethernet stage, you can see: 1. (CN14) RJ45 connector.2. (U11) magnetic-transformer.3. (U10) TVS diodes for diff pair signals.4. (U9) LAN-PHY device. First appreciation:Then you can see that not connected RJ...
