USART/UART question - how long does a comm line have to idle before the idle line condition/interrupt occurs?

How to reconfigure STM32L476 after exit standby mode

Posted on May 24, 2017 at 15:34Hi,We are working with SensorTile (STM32L476). To reduce power consumption, we are using the standby mode with sram2 retention. Our intention is to configure BlueNRG-MS (with advertising enabled), enter standby mode an...

What is correct to update PWM pulse width in STM32F0 HAL?

Posted on April 14, 2018 at 07:52 Hi, I am trying to learn PWM generation with STM32F030F3P6. Generated code using STM32CubeMX. Basic PWM generation worked fine. Now I am trying to change PWM pulse width dynamically in while loop of mai...

I must port code from stm32f100/200 over to stm32l05x, code has lots of fp calcs, is there software fp instruction support for l05x series?

simple things like:...float x = 0.5432;...x += 0.03;or... int y = 17;x = (float)(y*1.0); // expect result 17.0...

Problem in reading adc data (DMA based) for STM32L011F4 due to code size

HiI was using STM32L011F3 controller for my project. I am using ADC for 4 channels and I2C , timer peripherals. I downloaded stmcube32l0, in that STM32L011K4-Nucleo driver files i took because it is similar to my series controller. I developed the...

Tracealyzer in STOP mode

Hi,I have question about streaming data to Percepio TraceAlyzer when the MCU is in Tickless mode - in my case in STOP mode (main clock is stoped). I use FreeRTOS and STM32L152VB. My application periodically wakes up with period T=1.5 s. I use for tim...

Brown Out Reset does not work

Hello,we have a pcb with an STM32F765VIT6 on it. Everything works nicely except that there are unfrequent bit flips in the flash after disconnect and connecting the power supply..We tried to activate the brown out reset in software but after measurin...

RTC Running only in Debug Mode

Hi,I had generated RTC code for STM32L072CZ using cubemx, I'm reading the time and sending data via uart, when I'm in debug mode i can able to see the time via UART and when i stop debug mode then timer doesn't increment instead the initial value is ...
