Hello, I designed and assembled a simple circuit around the STM32G0B1KET and after connecting my ST-link it does not seem to "boot". My circuit looks like this: Additionally, there is a red LED through a 330Ohm resistor connected to 3.3vI am poweri...
Hi everyone, I need to power my F401RE with a 3.3V external power source. I read in the datasheet I need to connect the power source to the CN7 pin 12 or CN7 pin 16. Where do I connect GND signal apart from 3.3V signal?Also, from what I understood, I...
Hi all,I've tried every example I can find to send data to a terminal using UART on my Nucleo 144. Every time the code builds fine but there is never anything on the terminal, and the code doesn't get stuck anywhere it runs fine.
A PC app sends a reset command via USB. In the main app I use HAL_NVIC_SystemReset() to reset the board. If I use HAL_NVIC_SystemReset, windows loses USB com port and does not re-enumerate port unless I plug out and plug in USB cable. The PC app talk...
I already read this post with no success: https://community.st.com/s/question/0D50X00009Xka0fSAB/problem-with-the-nrst-pin-in-a-stm32f100cbt6I tried to design a simple board with a STM32L021K4 and to program it with a STLINK-v3 MINI. I got the follow...
STM32H7B3I-DK - Discovery kit use NX3215SA-32.768KHZ-EXS00A-MU00525 Crystal. Crystal Load Capacitance is 6, 9, 12.5 pF but STM32H7B3I-DK - Discovery kit use 1.5pF. Why it use different load capacitance.
I am using below componnet toolsMCU: STM32H7B3IIT6IDE: STM32CubeIDE Version: 1.9.0CRYSTAL: RT3215-32.768-12.5-TR ( 32.7680KHZ 12.5PF)I work with internal RTC. I will use for clock. But RTC clock behinds real clock. While the product is running, the l...
HiI wished to use my Segger J-link Pro to debug my Disco' Board, but when I connect using CN12 the Segger Spring Pin header it won't connect to the target, although the IDE and Programmer can "see" the j-Link probe. I read the board's user manual (UM...
