How do I have to configure the standard debug PINS (PA13 and PA14) on STM32F030F4P6 if I want to use them as GPIO output?
Currently I only set the MODER register to 0 and set the outputs to 0 with the BRR register since I don't need further configurations. I allready use other PINs with the same configuration and they work. I read that this should work, but on my HW it ...
Resolved! Does STM32L462RE have EEPROM? In the card that comes with the board says it does, however I can't find anything in the datasheet, nor on the website or the Hal driver files.
In the card that comes with the board says it has 16 Kbytes of EEPROM. Here is the link from the website (can't find anything about EEPROM): https://www.st.com/en/microcontrollers-microprocessors/stm32l462re.htmlAlso can't find anything about EEPROM ...
SystemClock_Config hangs
it seems my project hangs at this line ?if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); }What could be wrong?
Is driver for ST-link v2? digitally signed?
Hello , maybe I post this question to the wrong place...I would like to use ST-LINK/V2, Part number for required Software is "STSW-LINK009".In the description I can read "driver signed for Windows7, Windows8, Windows10".Could someone confirm that thi...
Unexpected oscillation from a GPIO pin STM32L562QEI6
Hello,please see the schematic attached. I observed 2 MHz oscillation (with 1V amplitude) on pin M1 (PA5) when I send a square wave with a period of 2 seconds.The GPIO is connected to that simple circuit, used to generate heat in the resistor.I used ...
Can't get my controller in Low Power mode
Hi,My controller still consumes 360µA in STOP mode, i can't figure out why.Maybe one of the inputs/outputs that leaks current?I have this IO setup the moment i execute STOPPA0-PA5 = External interrups up down edgle no pull up of downPA6 = ADC inputPA...
What's the Best LINK debugger/programmer for DualCore
I've been using Crossworks and J-Link for all of my embedded ST development.I'm starting a new project using STM32H747 and find I can't use my old tools.I am going to use STMCubeIDE for dual core development and would like to know the best debugger/p...
Experiences with Non original STM32F4 processors from China.
Hello everybody, we use STM32F429 processor in our devices. In the current lack of chips, we were forced to order chips from the only supplier who had them in stock, from China. The processor seems to work, but unfortunately it cannot be loaded other...
STM32 programming using ST link V2.
Hi, We are using STM32F407VG MCU for one of the project and for programming we are using ST link V2. The MCU has SWD pinout, when we try to connect the MCU using STM32cube programmer we are getting the below errors,ST-LINK error (DEV_USB_COMM_ERR)Err...
