NUCLEO-G071RB flash unlock hardfault
Hello,I'm new in ARM programming, I'm trying to study how CHIP work using the documentation.I wanna unlock the flash memory and according with documentation:1. Write KEY1 = 0x4567 0123 in the FLASH key register (FLASH_KEYR)2. Write KEY2 = 0xCDEF 89AB...
Resolved! STM32G030 PCROP bit missing. Clearing RDP does not perform mass erase
Hi, I'm using the STM32G030 MCU and I want to perform programming using the CLI commands. When using the STM32 ST-LINK utility and opening the option bytes window, I can see the PCROP bit which if I set, the MCU performs a mass erase when RDP bit cha...

Hello!What is the difference between JTRST and NRST of stm32 mcu?When using SWD, where should the RESET pin be connected? NRST or JTRST?
Resolved! STM32U575 : simple USB VCP UART
I have my own little board: with STM32U575CIT6Q (LQFP48 package). The USB is very simple and just DM (PA11) and DP (PA12) are connected. No USB-C, no USB-C Power Detector neither external chips for USB-C (as on NUCLEO-Board for USB-C-power).I want to...
Resolved! STM32U5xx: QSPI as multi-master (release QSPI signals)
I use the OCTASPI as QSPI. So far ok (QSPI transactions work).But I have realized:a) the QSPI does not release any signals after a transaction has finishedb) it does not seem possible to use OCTASPI (in QSPI mode, maybe as well in single SPI mode on ...
STM32F103C8 GPIO Output
I'm trying to control LED using GPIO.The GPIO pin settings are as follows.PB 8~15 : input dataPB 4~7 : output LEDAfter analyzing the input data, I want to export the output, but when PB 4 is exported, PB 12 is turned on, and when PB 5 is exported, PB...
Resolved! STM32F4 Discovery 1-2% Accuracy ADC
I am just now moving over from ESP32 to STM32 Discovery. One of the features that I like about the STM32 is that there are 3 ADC and several accessible channels.In my previous design on the ESP32 I used external ADCs and communicated with them using ...
How to Communicate with UART Sensor on USART6
Hi all,So I'm trying to communicate with a dust sensor (SMUART04L) via USART with the use of an STM32 F411RE. So far I have been able to connect it to the board and get a response of 0x42 which according to other online sources and datasheet is so fa...
