STM32L0x2: Combine two comparator outputs

I have a STM32L072KB microcontroller and want to combine two analog signals (they represent a kind of "quadrature encoded signal" with a 50% duty cycle) into one "combined digital output signal", which have the doubled frequency (for my purpose the d...

Resolved! delay function based on timer, overflow safe?

Hello Everybody,I was thinking about a flexible way to implement a µs or ms delay function with a free running timer as tick source. One of the biggest problems that comes to my mind is the overflow problem when the timer wraps around, so that some c...

STM32F103 PC13 variable duty cycle waveform

I'm intending to use PC13 as an output to drive the onboard LED, but at some point in my program the PC13 pin begins outputting a 4.4 khz signal with pulse width that varies from 0% to 100% back to 0% and keeps repeating that pattern at approx 4 Hz. ...

I am trying to interface a GSM sim7600 module with the STM32F446RE, but i am not getting the response on the UART.

I have checked the PIN they connected in the correct order and on the correct pins. I have checked the GSM module on hyperterminal and it is functioning as intended. I am using the HAL drivers and Kiel IDE.I am trying to get the response from the com...
