Using an STM32F030F4 20-pin for a battery powered application with just a low quiescent touch tensor (active high) for wake-up from low power stand-by on low-to-high and high-to-low sensor edges.

I'm considering an STM32F030F4 20-pin for a battery powered application. Might a low quiescent touch sensor (output high) in conjunction with the timers/functions onboard the chip be used to wake the chip from low power stand-by on the rising and fal...

How to see a graph from an array?

Hi all,I'm taking a lot of readings from the ADC, and store those reads in an array (reads[2000]).Is there a way to sohw a graph from the reads, using STMStudio or another program?

STM32F446ZE doesn't enter in Standby mode

Hi,I am using Standby mode on STM32F446ZE, but I faced with a problem. Sometimes MCU doesn't enter in this mode. Exiting Standby mode via RTC wakeup.Below is present steps which I perform for entering StandbySCB->SCR |= 0x00000004;PWR->CR |= 0x000000...

Resolved! PWM capture using Rising, falling EXTI

Hi all,I am capturing 10 pwm pulses from proximity sensors by making the all pwm pins in rising falling interrupt mode.PWM is captured by a timer at every 100us interrupt.some times pulses are missing, I don't know why this is happening.I am sharing ...
