Resolved! How to measure STM32F767 zi only microcontroller part power consumption using X-NUCLEO-LPM01A
Hello, i want to measure the power consumption of STM32F767zi only MCU Part using X-NUCLEO-LPM01A. The step of manual says to "open the SB110" by default SB110 is ON what are the ways to make it open ? can we do it through wires or some jumpers?
STM32F3348-disco USB connection fails
When connecting a brand new STM32F3348-DISCO board to USB on my MacBook Pro (M1, Ventura), USB communication fails and the ST-Link is not recognised. LD2 flashes brightly red and LD1 flashes hardly visible.Sometimes the communication works for a very...
Error in initializing ST-LINK device in the STM32 Nucleo-144 evaluation board
Hi guysI am using the STM32 Nucleo-144 evaluation board and trying to upload the program by the STM32 ST-LINK Utility.When I try to connect to the board, the console always shows the following error message: "No target connected," "Can not connect to...
Resolved! What is the correct power supply circuit of PL2303 UART Brigde with STM32F407VG (Discovery)
At first, I'm an absolute beginner, I'm still on my way to learn more about STM family regarding electronics.Lately I've been having circuit issues with PL2303. After reading datasheet, number 6.2,5V can also be used as input power suppliesI've conne...
NJTRST different from NRST on STM32L412
Using the STM32L412 I use the PB4 for the signal NJTRST of debug connector and the ST-LINK does not work fine (but it works using J-LINK). We use also H723, H743, L476 and L496 connecting NRST to debug connector. This can be done with L412?Best Reg...
Resolved! Hello, I am starting the new project and i want to use stm32 mcu L152Re based in my own PCB , but i am unable to find the eagle files for that. Can you please help me to provide that.
Currently I am using STM32 Nucleo-L152RE , so i want eagle schematic file for that also to take reference for my pcb hope you will help me
Connection and external components for SMPS
Hi, I have some questions about the connection and its external components for the SMPS step-down converter of the MCU.The microcontroller I'm using is a STM32H745IIT6. On the datasheet I found this schematic and these indications for the components:...
Resolved! Which pins of the Stmod+1 & 2 connectors correspond to the MCU pins for the B-U585-IOT02A board?
I cannot find the logic in the schematics about the mapping of the 2 stmod+ connectors.Which pins of the stmod+ correspond to the MCU pins ?Page 7 of the schematic folio is very confusing.I just found pin 3 & 4 of the stmod+2 to be mapped to PG10 & P...
STM32F7508-DK NRND'd
https://www.st.com/en/evaluation-tools/stm32f7508-dk.html is NRND'd.It's no huge loss, though, as it's an identical board (MB1911) to the 'F743 'F746 Disco (thanks, Clive!) which is still Active.JW
