STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on December 09, 2015 at 09:21hi, in my project we are using virtual com port for a communication between pc(usb) and stm32f103(USB). But due to ground loop and noise we are facing communication problems. so, to over come this we are planning ...
Posted on April 11, 2014 at 08:05Can some one please help me out my issue is ,I have a STM32 Hy mini board which I am trying to log data onto a SD card through SDIO interface but ''f_write'' function hangs while writing 1092 bytes of data stream ...
I saw demo example (PWR, stop1 without RTC), but I want to use LPTIM (without hardware interruptions) to generate sometimes PWM with TIM2 and go on in STOP1 mode.Thank you for answer!
Hello. I use STM32L432KC and can't understand how to configure LPTIM(2), STOP1 mode and general-purpose timer (TIM2) so that while LPTIM is active (between timeout periods) I could generate PWM with TIM2 and all time excepting that MCU would be in ST...

Posted on June 16, 2018 at 13:49Dear All, I am working on STM32F4Doscovery board timers. I want to make a timer interrupt for an application. It can be 1sec or 500ms interrupt. I have read the datasheet and written the program accordingly. But i d...
Posted on August 10, 2017 at 04:01Hello,I am working on porting code from IAR EWARM to Atollic Truestudio for STM32F103RD microcontroller. For the __ramfunc IAR directive I have added __attribute__((long_call,section('.RAMFN'))) and modified the lin...
On Reference Manual RM0008, pag 186, bit 2, Alternate Function I/O Remap, it stats that the only available pairs for Usart 1 RX/TX can be PA9/PA10 or PB6/PB7, but on the pinout image for the same NUCLEO-F103RB the Usart 1 pinout is on PA2/PA3.Which o...
