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?

Pourquoi avez-vous utilisé le protocole UART puisque le capteur à ultrasons HC-SR04 n'a pas de broches RX et TX ?
@vladmaftei4858
@vladmaftei4858 7 месяцев назад
On a utilise le protocole UART pour recevoir les information echox, distancex dans le terminal Hterm program qui est ouvert sur le display (gauche).

@@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 ?

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

I think other one should be TIM8.

Hi, are stm32 pins tolerant to 5V from hc-sr04 echo output? Did you use level shifter?
@wyznacznik5363
@wyznacznik5363 3 года назад
you need just 2 resistors, i used 9.7 Ohm and 4.6 Ohm so i get 3.4 V
