COOL! I used the timer input capture in DMA mode to make it more efficient, but very good stuff.

HI, sorry, why preescaler is to 79 and ARR is 65535 in TIMER8, what is the measure that do you want?

[baole]

how to connect between STM32 microcontroller and HC-SR04 ultrasonic sensor.?

[GhionAshenafi]

Couldn't find z video u mentioned is present: calculating prescaler and other values

[saraazizi]

How you connect between stm32 microcontroller and ultrasonic sensor?

[halilaaydemir]

I could not set up the link. Do you have a chance to show the link?

[saikrishnakaruturi]

at what pins in the microcontroller do we have to connect the trigger pins of the both sensors

Pourquoi avez-vous utilisé le protocole UART puisque le capteur à ultrasons HC-SR04 n'a pas de broches RX et TX ?

[firasoiderni]

Goodmoring,
i wanna ask a question, how you interface Hterm with keil ?, and thanks advance :)

I have a question: Why should we start TIM11 base clock twice?

Hi, are stm32 pins tolerant to 5V from hc-sr04 echo output? Did you use level shifter?

This guy copied from somewhere that makes him did not do well in the video. He also could not answer people questions. Shame!
