Posted on June 11, 2013 at 09:25Hello! lately i configured the RTC to work respectively to the LSI oscillator. The RTC is working well while supplied from VDD pin. when working from the VBAT the last time count is preserved but from turning off to ...
Posted on June 11, 2013 at 08:59Hi,I have selected an STM32F2 MCU for various reasons and I need to run it in the lowest power possible.The CPU will run most of the time et low speed 4 or 8 Mhz. For this I was thinking to use a 16Mhz crystal and byp...
