I have a Nucleo-H723ZG board. The GPIO lock bits are set at reset so I cannot set up the ports. See Attached screenshot. I can run code just fine and the original demo code did toggle the LEDs. Am I missing something here?
Hello everyone, I have a problem with the bootloader of the stm32h503 microcontroller. I can't get a response from the stm32 via any of the UART interfaces. I tried different baud rates (9600,57600,115200) but I don't get an ACK from the STM32H503 in...
First of all, this problem is related to ADC and OPAMP, in the program I designed to enable adc1 and adc2, as well as opamp2 and opamp6.The clocks of ADC1 and ADC2 come from the output of the PLLP and each set the same sampling time. The TRGO2...
hi. i am trying to save a data into stm32h7b0vbt6 flash memory. so i have used HAL_FLASHEx_Erase to erase one of the sectors and HAL_FLASH_Program to program it. it works and flash will be programed.but when debuging, code gets stuck to while of the ...
Dear STM32 Bluepill Community,I recently acquired an STM32 Bluepill development board and have been attempting to establish a communication link with my computer via the USB interface. Unfortunately, my computer is not recognizing the COM port associ...
i have been using stlink v2 for a while now, but today it wouldn't connect with any of my stm32 boards the error mesage that apears is STMicroelectronics ST-LINK GDB server. Version 7.9.0Copyright (c) 2024, STMicroelectronics. All rights reserved. St...
HiIs the UNIQUE ID of the STM32H562RIT6 microcontroller, which consists of 96 bits, entirely variable, or does it include fixed bits as well? Which bits are fixed?
Hi,I have a custom board which has an STM32F446RE with implemented SPI peripheral that should communicate with MAX22530 chip. Currently, I am trying to test the SPI interface but am running into something that looks strange.The SPI ioc configuration ...
