Hi, I have 3 STM32F091 chips that have their factory HSICAL defaulting to 0x0F as opposed to HSICAL = 0x5C/0x60 on working units.I'm using STM32CubeProgrammer.I suspect this happened when I had enabled RDP Level 1 / BB, then I needed to update the fi...
In one of my projects I'm using USB Host with STM32F407, It's working fine for both keyboard and mouse but while using Motorola Barcode scanner i face some issue related to USB host ID as it keeps on changing. It will connect with " HID_Device " Id, ...
Hello!I am trying to wake up STM32L4 from STOP2 mode on each 3 seconds using RTC.This is the RTC initialization code:static void MX_RTC_Init(void){/* USER CODE BEGIN RTC_Init 0 *//* USER CODE END RTC_Init 0 */RTC_TimeTypeDef sTime = {0};RTC_DateTypeD...
I am having a problem with the USART on my STM32WL55JC2. I have configured the USART correctly, and I am using the correct pins, but the USART is not working.I have tried the following to troubleshoot the problem:I have checked the configuration of t...
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...
The issue I am having is as follows on the STM32G051C8T6. We are using the internal RTC with Vbat pin. On this MCU Vbat can be internally configured to be read by the ADC by diving by 3 Bridge. We have ADC Setup, I am making sure we perform the ADC C...
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 ...
