USART without response when disconnect a STLink.
Hello everybody. I have tried to configure the output of a sensor for a display and it has worked, however, it only works when I am connected via STLink, when I feed the circuit by 3.3V or 5V, there is nothing on the output. Can someone help me?
Resolved! I try to connect a Nucleo-64 board via ST-Link/v2 for debugging, but it doesn't work. I removed CN2 and and pinning as specified. But nothing happens, no connection and no led on. The ST-Link/v2 is solid red, so it should be ready.
I'm using this guide: https://stm32-base.org/guides/connecting-your-debugger.html.
STM32L431 DAC
Which DAC method is used for STM32L431, R-2R or resistor strings?Different things are written in the two materials. https://www.st.com/content/ccc/resource/training/technical/product_training/01/4b/81/0e/21/a6/4c/55/STM32L4_Analog_DAC.pdf/files/STM32...
Resolved! X-NUCLEO-LPM01A Board wrong voltage after calibration?
Hello,I'm using the X-NUCLEO-LPM01A Board. Today I encountered a problem with the calibration. If I set the voltage to 3.3V and run a calibration I measure at VOUT only 3V. Without any calibration I measure the expected 3.3V. If I set the voltage to ...

Can I use serial resistors to have "some" ESD protection on IO pins? Would 100ohms help at all or should I just remove them?
I am using STM32F207 on the main board for an industrial remote control. The radio connector is connected to the MCU.
Resolved! HW design
Hello, I have to design a circuit and I need help. There are two external devices, which the third device with MCU STM32F105 has to find out which of them is connected to it. Two external devices have signals:- 24v or non-connected - GroundI can mayb...
