STM32L4 BusFault_Handler
Posted on December 05, 2017 at 09:50I'm developing an application based on STM32L4 on a custom board. Program is running fine but I noticed that sometimes (maybe once after four days working) device is reseted. In order to find the reason of this re...
Timer with low power mode
Posted on November 30, 2017 at 11:49Hello all I'm working on STM32L152RE nucleo board. I ain't able to integrate Timer in low power mode .so is it possible to work with timer and low power mode in STM32L152RE simultaneously?If yes, which timer is ...
Coin cell to VBAT pin on a Nucleo board?
Posted on November 20, 2017 at 22:35On a Nucleo board, is it as simple as pulling the 0 ohm resistor off SB45, and connecting a coin cell [something like a CR1220] to pin33 [VBAT] and ground, in order to have battery backup for the RTC registers?
STM32L476 PE11 stays high even when not driven by input
Posted on December 05, 2017 at 01:15I was wondering if there was any explanation for having several Port E pins (10-13) set to Input (00), and pin E11 is staying high even though there is nothing connected to it. I have tried setting the GPIOE->PUP...

STM32L4 Wakeup Delay from Stop Mode (Stop 0)
Posted on November 27, 2017 at 20:27Question: How to achieve the 4.5 us wakeup time for the stop mode (Stop 0)? The board I am using is STM32L476 NucLeo. I am using the MSI clock (48 MHz) as the system clock. After awaken up, the MCU runs the 'HAL_A...
UART IT
Posted on December 04, 2017 at 18:18I am using Nucleo F334 and STM32 Workbench as IDE.I need to build a bridge between UART2 and UART3. It should work this way: data are continously acquired on USART3_RX by interrupt and transmitted on USART2_TX.I a...
Resolved! Firmware Working in Debug but not on Stand Alone
Posted on December 01, 2017 at 16:08Hi,I'm developping a firmware with a stm32f405zgt6Unfortunatly, I debug the code, step by step, and it's working fine, but then, when my board is on stand alone mode, the firmware is not working. It looks it even ...
