Hello,I am currently working on a project involving transferring data acquired with an ADC through ethernet.Im am using the STM32H743 MCU.I have been building small projects using LWIP, and was able to connect to the board, ping and transmit some arr...
I am in the process of designing a custom PCB board that uses the CN4 ST-link pins to flash to the processor (rather than the standard USB Micro-B connector). Through testing with a multimeter, I have confirmed that the CN4 line is connected to the ...
Hello guys. I got two STMF411RE Nucleo Boards and i want to start 10KHz pwm signals on each one of them with 25 microseconds delay between them and i MUST use an external trigger signal (Main synchronization computer) to trigger those STM's to create...
Hi, I'm using STM32H750-DK as an example to build my board. And I don’t know for what purpose resistors R121 - R158 are installed. Can I directly connect these pins to ground?
Hello, I'm currently trying to receive some data from device #2 (legacy device, not a PC) with my uC STM32 (device #1). But in order to receive the data I need to generate a pulse in the DTR pin or CTS (both are connected in the device #2) on the con...
Hi! When I connect stlink v3 minie , lounch cubeide -> stlink upgrade , it only shows "V3", nothing more. I can't open it for upgrade.Other embedded in nucleo boards stlink v3 works and can be upgraded (nucleo G431 and H723).There is an error about ...
Hello. I was powering up my NUCLEO-F446ZE microcontroller board using an external power supply of 5V. I set the jumper JP3 to E5V. I made some changes in the code and tried to connect the board to the USB to burn the code to its memory. I forgot to r...
Hi, Im using internal ADC for ADC calculation.The noise is getting generated for low voltage signal can someone please tell me how to reduce it as im facing the issue of finding the zero crossing in the signal?
How to get the height difference of these two screw hole?
I'm using system bootloader to write to flash memory on NUCLEO-H503RB evaluation board. The interface used is UART. I received ACK confirmation (0x79) for every command I sent: UART bootloader activation (0x7F), Extended Erase Memory (0x44) and multi...
