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...
In the target voltage I can see not detected. I have removed the ribbon cable and have connected using jumpers now, pins in the following manner:1 - VDD7 - SWDIO9 - SWCLK3, 6 - GNDI don't know what is going wrong with the ISOL version of the STLINK v...
Dear all,I have tried to follow AN2867 for choosing an 8MHz crystal as HSE in the STM32L496.Doing this: Starting from the crystla included on Nucleo BOM, NX3225GD-8.000M-EXS00A-CG04874, I look for a 12pF crystal like this. Assuming Cstray=10pF, I ha...
Hello.I am a STM32F407VE user.I am trying to load a program using ST LINK V2, but an error occurred and the program could not be loaded. The error is as follows, and if there is anyone who can solve this error, please let me know. thank you.
16:32:00 : ST-LINK FW : V2J39S7 16:32:00 : Board : -- 16:32:00 : Voltage : 3.22V 16:32:00 : Error: No STM32 target found!
How do I set/reset a GPIO pin on CN1 like D8 (PB2, pin 37 of STM32L475VGT6) of B-L475E-IOT01A ?This is NOT working:HAL_GPIO_WritePin(GPIOB, GPIO_PIN_8, GPIO_PIN_SET);Also, is there a code line or two to set as pull-up or pull-down output and initiall...
