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 July 01, 2011 at 15:21HI..in attach file there's my code. i've to manage smbus using interrupt (no polling allowed). I don't understand why the interrupt doesn't start. The code doesn't me any error. Is it correct manage the smbus protocol...
Posted on June 30, 2011 at 23:11I am doing a STM32L152 design, using IAR tools, and have run into problems with JTAG programming. My code resides in Flash, and sometimes there is a JTAG ''no communication'' problem which prevents me from programming...

Posted on June 27, 2011 at 12:13Good morning everybody! I'm evaluating ST standard device Library with STM32L discovery board. I want to test RTC and so in my main I want to call RTC_Init and so on. So I prepare a RTC_InitType structure, I create a...
Posted on June 28, 2011 at 09:38Hi All, Can anyone explain the difference between the prem and sub interupt priorities. For example what TIMER_1_IRQ_PREM_PRI and TIMER_1_IRQ_SUB_PRI. -- Thanks #stm32-c-embedded
Posted on June 29, 2011 at 13:02Hi, i've to implement a RTC calendar on my STM32F100 microcontroller. I've the RTC library, but i'm searching a so called ''calendar.h'' that already has defined: days, weeks, months,years etc.. Some ideas?? #time...
Posted on June 26, 2011 at 19:08I've built a gas turbine engine, which currently runs on a variety of manual valves/switches to run. What i want to do is to install solenoids into my fuel rings/pump supply, and relays on the switches controlling my ...
Posted on June 27, 2011 at 12:34I am trying to implement EEPROM emulation in the flash memory. I am able to write and read the data from flash. When trying to write the second data it is going to HARDFAULT Error. I m not sure why this happens. Belo...
Posted on June 24, 2011 at 16:49Hello, I have: a STM32F103RC, a fresh 3V Li BATT, a 32.768kHz crystal and my own RTC support library. I works, but... The manual RM0008 (Doc ID 13902 Rev 11), page 454, says:If the input clock frequency (fRTCCLK) is...
