Question about chained timers (again) and how to avoid wraparound glitches

2022-06-13
Hello, I ask this same question a month ago, but i want to reformulate the question to better understanding. I need to implement a lifetime counter using the nucleo-stm32L432kc timers to send the number periodically to an AFBR-S50 sensor. I think the...

Why is voltage dropping too much in the 5V output Nucleo-STM32L432kc

2022-05-11
Hello, Im trying to power this board and sensor with 30mA power consumption @ 5V with 5V output of the board. What im noticing is the board is not capable of mantaining the voltage with this light consumptions. It starts at 4.7-4.8v with nealy 0mA co...

Falling edge trigger extternal interrupt not detected because different TTL levels?

2022-05-05
I have problems detecting a falling edge external interrupt. I can see with the tester the signal changes from 3.2v to 0v so its produced but the the interrupt is not generated. Could the 3.2v instead of 3.3v the problem?Signal is oscillating 3.19-3....

Periodic Interrupt Timer with dynamic period set (programmatically) not being generated

2022-05-02
Im in the process of configuring a STM32L432KC to talk with an AFBR-S50 sensor. This sensor needs a periodic interrupt to trigger measurements periodically. In the example they are using a timer with down counting direction to generate the interrupt ...

How to correctly chain 3 timers and fix the overflow and wraparound issues.

2022-04-29
I have to implement a lifetime counter with microseconds granularity using a STM32L432KC to control an AFBR-S50 sensor. The timer has to count "forever" and this board only has 1 32bit timer, so this timer is for the seconds, i think is the only way...
