Hi! Just as a comment, did anyone had that kind of problem?uC is not found or easily losing connection while erase/program.Everything is properly designed and soldered (even programmer pins are temp. soldered to board).Every connection was checked an...
I have an Arduino Giga (STM32H7), and I'm trying to generate PWM's. I succeeded using alternate function AF9 of PA7 (digital pin 5), which uses TIM14_CH1. Now, using the exact same code (as far as I can see) but using PA2/PA3 (digital pins 3 and 2) a...
When you look at your Nucleo-f207zg board, ethernet stage, you can see: 1. (CN14) RJ45 connector.2. (U11) magnetic-transformer.3. (U10) TVS diodes for diff pair signals.4. (U9) LAN-PHY device. First appreciation:Then you can see that not connected RJ...
We are currently using STM32G0B1VE. But we are having NUCLEO-G070RB evaluation board. Can we use the NUCLEO-G070RB board for developing the code before the actual board arrives?
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 ...
