I have a low frequency (~1 kHz), low duty cycle signal that I'd like to capture rising edges of. What's the minimum width of those pulses to capture them using a timer in input capture mode?I see there's a programmable digital filter there, in terms...
HelloI designed a card with STM32L052C6T6 mcu, but I can't find this mcu in Turkey.What would you recommend as a pin to pin instead..I found stm32f103c8t6 but if anyone else please advise
Hello Our STM32G4 is measuring a sinus-ADC value with offset. The offset is at VDDA/2.Our ADC measurement shows a plateau at the offset, even, when the sinus signal is crossing the VDDA/2 (see attached picture).The signal them self seems to be ok (me...
After reset MCU init UART - 8bits, no parity bit, init DMA RX and TX, interrupts on - works Ok.Reinit UART - 9 bits, even parity bit, no DMA - works Ok.Reinit UART the same as p.1 - doesn't work interrupts.
Hi I have been thinking about making a 3 axis gimbal with Arduino and an MPU6050 for some time now. I went around the internet for a while and saw that there is a project that manages to control three brushless motors only with arduino as if they wer...
I'm looking for a trace port analyzer. Does anyone have any recommendations?
I'm working to read 2 identical encoders from 2 identical motor drivers.I use TIM2 and TIM3 to read the encoders.The encoder at TIM3 works properly, but the encoders at TIM2, I could see in debug mode the IRQ but the register CNT is zero. But every t...
Hi,I am working on STM32H745 discovery board and trying to configure the onboard 4GB eMMC flash over SDHC1 interface. I am loading default discovery board configuration by the CubeMx configuration, which sets both M7 and M4 and all AHB buses to run a...
I've seen the discussion in an old question herehttps://community.st.com/s/question/0D50X00009XkbAd/how-to-protect-analog-inputs-Accordingly, ADC inputs are not 5v tolerant in ADC mode.I started studying some Zener diodes, in particular 1n4727 Vz 3vh...
