STM32L412 32.768kHz Crystal Layout Queries

Hello,We are facing RTC Drift as mentioned in previous question, So We have some queries regarding PCB Layout.1) GND of Crystal's Capacitor is connected to nearest GND Pin of STM32L412, should I connect this MCU GND Pin to Common GND Plane?2) How sho...

connecting directly my nucleo u575 using an external stlink

I'm struggling to connect directly my nucleo u575 using an external stlink. I have opened JP2, closed JP1. The pinout of connector CN5 is the following: 1 Vdd, 2 SWDIO, 3 GND, 4 swclk, 6 SWO, 10 target reset. The pin out of the stlink is 1 Vcc, 2 SWI...

How to configure RCC in STM32 Cube using NUCLEO-L496ZG and on board crystal resonator

I entered an inifite loop at the HAL_RCC_OscConfig (l 29) of SystemClockConfig() ​void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};   /** Configure the main internal regulato...

Does TCPP01-M12 Source Pin (pin 4) really have a 5.5V Absolute Max voltage limit?

Table 3 of DS12900 - Rev 6 shows a max voltage of 5.5V, which doesn't make sense, unless I'm missing something very important.Is this just a typo? Seems like it should be on the same line as the GATE pin or IN_GD.Thanks

ST-Link V2 SWD connection by using just SW_DAT, SW_CLK and GND.

I have a custom board powered by using USB, if I need to program a firmware by using the SWD feature in the ST-Link V2 Probe, may I connect just following 3 pins (without VDD) ?- TMS_SWDIO (pin 7)- TCK_SWCLK (pin 9)- GNDDo I need also to connect VDD ...

I am trying to understand and implement a method of reusable code, starting with STM32 projects. Any ideas on the best method(s)?

Hi,I am trying to implement a method of reusable code starting with STM32 projects. I have multiple micro controllers (F4, F7 etc) that will need to run the same application code. As STM generate the Drivers/HAL for me. Would I need to write API func...

Can I know the program board,programming code and circuit diagram of the air conditioner machine of STM32L010C6 microcontroller please?

Can I know the program board(development board) and programming code of STM32L010C6 microcontroller please? Also can I get the circuit diagram of the air conditioner machine. I only found the block diagram.

Hi, I am using STM32H7A3ZI.I tried to debug but I am getting Target no device found.Error in initializing ST-LINK device.Reason: No device found on target. please help to resolve this issue.
