Question about usage of pins like TIM2_CH1_ETR, TIM8_CH4_BKIN2, etc
Posted on June 08, 2013 at 18:29The datasheets don't detail how these pins are connected internally. Can someone shed some light on this?Can I use these pins as output compare outputs? i.e. PWM outputs?
GPIO power on STM32 (STM32F205RBT6) can be different voltages?
Posted on June 07, 2013 at 18:47Good morning. First time poster. I am somewhat new at using the STM32 line of MCU's and have a general question that nobody can seem to answer for me. I am using the STM32F205RBT6 inside of a design. The STM32 will...
