HSE oscillator power consumption

Posted on May 22, 2015 at 12:25Hello,I estimate the total power consumption of a device operating from the HSE oscillator. The MCU part number is STM32L152RBT6.I configured the MCU to operate from the MSI oscillator (2.1 MHz). All the GPIO are confi...

Comparator rising/falling edge propagation delay

Posted on May 22, 2015 at 11:17I am using a STM32L152RC microcontroller and have to detect the length of pulses of about 0.7 V and 3 ?s using the COMP2 comparator. At 2.7 V VCC the worst case propagation delay is 2 ?s in fast mode. A minimum delay i...

STM32F100(RBT6): PWM generation with TIM1

Posted on May 24, 2015 at 19:17 Hi Guys, I am very new to the STM32 family and right now I am using a STM32F100 to be able to generate a PWM with TIM1. The end goal is to generate a PWM that can be filtered to show a sinewave so I need v...
