stm32 write serial number
how to write SN for hundreds MCUS? i know j-flash can write fixed bytes,i need to write custom 10 bytes SN which has its own generation rule

[STM32F429 Flexible Memory Controller (FMC)] Is the write operation blocking for the CPU? (NO BURST MODE)
I couldn't find this info on the Reference Manual, maybe because it is trivial, in case I'm sorry. When the CPU performs a single STR within the FMC address space, is it blocked until the entire write cycle of the peripheral is complete, or it only w...
Frequency limitation when trying to generate a 2us period on a Timerfor the STM32F7.
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?
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...
Systick and Timer on RTOS ?
Dear Members,I'm doing experiment with RTOS, what's the different between Timer and systick when using RTOS ?Thanks
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...
Can Vbat be monitored in Sleep Mode (or another low power mode)?
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...
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...
