Hi, I'm trying to generate a 500KHz counter on TIM1 on the STM32F7 to trigger an ADC conversion and I'm currently having issues as it seems to top out at 360KHz. I'm toggling a GPIO pin with a scope to the input and simply changing the Period on the...
Is there some sort of foiling problem with PA6 on the NUCLEO-L496ZG board? I am trying to setup PA6 to be the OPAMP2 positive input. There always seems to be 3 volts stuck on this pin with nothing connected. PA0 works just fine when configured for OP...
Dear Members,I'm doing experiment with RTOS, what's the different between Timer and systick when using RTOS ?Thanks
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...
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...
Hi,I'm using a Nucleo F429ZI and want to use a low power mode after I lose supply power and am relying on a battery (connected to Vbat). I am wondering if it's possible to monitor Vbat while in a low power mode (like Sleep Mode) and what the best way...
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...
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...
Hello,I need to connect STEP/DIR driver (DRV8825 to STM32F103) for driving one axis stepper motor. I will use buttons for moving and I need to set acceleration and deceleration profile. Do you have some experience what way of pulse generation I shoud...
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...
