Using an STM32F031, can I have one ADC channel being monitored by analog watchdog and another channel being scanned in each iteration of the main loop?

Lets say I have channels 1 and 2.I was wondering if I disable continuous scan and enable watchdog on 2. Will the interrupt for channel 2 be called only when I do a start scan or will the watchdog keep continuously checking the channel 2?In other word...

STM32 Rotary Encoder Pulse Count

Is it proper way to to count encoder pulses using rising/falling edge interrupt instead of using Timer in Encoder Mode??Because in my application I need interrupt above 80000 pulse count. But here timer is of 16-bit (STM32F103C8T6) so it can only cou...

STM32F030C8 warm start failure

We have several STM32f030C8s that refuse to start if the ambient temperature is 40deg C. Below, say 20 deg C, they start and continue to run up to and beyond 40 deg c ok. Applying a reset on a stalled processor brings it to life. Is this a known p...

Resolved! Rotary Encoder Application

I am using STM32F103C8T6 for counting rotary encoder pulse.My Encoder PPR is 5000.But when I program for timer1 as encoder mode and show count on segment it shows 20000 pulse per rotation it is 4 times higher than the actual value. What should I do t...

I config timer'mode is TIM_OCMODE_ACTIVE  , start enable ,can output waveform,but enable more than one time , only output the first corresponding waveform .why behavier so ?but when I config timer TIM_OCMODE_PWM2( or TIM_OCMODE_PWM1 ),enable and di...

Resolved! TIMx Clock Division Configuration

Hey, I am trying to understand timers, everything goes nice, but I have a question in my mind.I am able to set the prescaler and period values according to my purporse, but I can't use the internal clock division effectively.My TIM2 clock signal is 1...
