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

[@erykmroczko8427]

Can you share your code?

[@enriquehernandez8197]

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

[@takwasmidi3284]

did u find the answer ? :)

[@baole8008]

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

[@thanghieu2333]

t cũng đang làm cái này và k biết nối làm sao

[@GhionAshenafi]

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

[@saraazizi2198]

How you connect between stm32 microcontroller and ultrasonic sensor?

[@muhajideenroom]

Look at google:)

[@saikrishnakaruturi2958]

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

[@kiranami-q6t]

Did you find the answer?

[@raguelignacio3808]

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

[@emirozer2855]

I think other one should be TIM8.

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

[@vladmaftei4858]

On a utilise le protocole UART pour recevoir les information echox, distancex dans le terminal Hterm program qui est ouvert sur le display (gauche).

[@narwresbarhoumi2292]

@@vladmaftei4858 merci j'ai compris , j'ai une autre question c'est vrai que vous avez fait la configuration du protocole ,mais vous n'avez pas utiliser HAL_UART_Transmit() dans le while ,je sais que vous avez mis ça dans la fonction putchar_prototype mais vous n'avez pas utiliser cette fonction dans while ?

[@halilaaydemir]

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

[@sw1746]

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

[@wyznacznik5363]

you need just 2 resistors, i used 9.7 Ohm and 4.6 Ohm so i get 3.4 V

[@firasoiderni8676]

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

good work sir

굿

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