Hi,I found two bugs related to priority group in STM32CubeIde 12.0 and newer. When try change priority group in NVIC tab, for example from NVIC_PRIORITYGROUP_4 to NVIC_PRIORITYGROUP_2, HAL_Init() function always use NVIC_PRIORITYGROUP_4: HAL_StatusTy...
I'm working through some code size optimization efforts and noticed that our list file includes some calls to __assert_func. We're not using asserts in our codebase so I'm guessing one of the standard libs is using it. I checked and we have defined N...
I am reading the "Getting started with STM32U5 MCU" guie, which mentions that JTAG/SWD lines should have a 47-Ohms resistor and a 6.1V diode for ESD protection,.I am using s STLINK-V3SET to program a custom board. STLINK already includes these compo...
I needed a help how to implement shutdown mode and wakeup from external reset in my application while (1) { HAL_Delay(100); // MAINS INPUT Adc_Mains(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1...
Hi all,I'm working with an STM32WL and I'm looking for an information I can't found. I have a voltage divider with 2 resistors to meseaure the battery voltage. I'd like to know what is the minimum current that the stm32wl can have on an analog input ...
Hello everyone, i am having issues with my board, I can't load to it. I am getting data read failed when i open stm32cubeprogrammer the OB PCROP DMEP box is checked (I did it) and I can't find a way to uncheck it. I have tried the ST-LINK_CLI.exe too...
Hello,I am trying to put my STM32F103C8T8 in sleep mode where all clocks are running etc. and wake it up using external UART interrupt.I am using MikroC as an environment and I don't think they have Wait for interrupt function. Is there any other sol...
I am using 2 devicesSTM32L4A6VGY6P (package WLCSP100L) STM32L4A6ZGT6P (package LQFP144)My FW needs to differentiate between these 2 devices and so the package data register (0x1FFF7500) seems like a no brainer to use for that.The problem is my WLCSP1...
Hello , I am searching for solution that my code is stuck in the hal_delay function. I couldnt figure it out exact solution. Indeed, this problem is posted in community many times. When I try to initilize the code form cubeMX and test it on --nucle...
Hello, Our goal is to implement field firmware updates in our application and would like to gain a general understanding of how it works at ST.From reading the Application note: STM32 microcontroller system memory boot mode, my understanding is that ...
