Hello can I help please.
Im ESP32 - MODEMCU32S a connect to HX711 a waight senzor.
But problem dont found senzor.
My cod:
#include "HX711.h"
#include "WiFi.h"
#include "Wire.h"
#include "stdio.h"
#include <Arduino.h>
#if CONFIG_FREERTOS_UNICORE
#define ARDUINO_RUNNING_CORE 0
#else
#define ARDUINO_RUNNING_CORE 1
#endif
const int LOADCELL_DOUT_PIN = 23;
const int LOADCELL_SCK_PIN = 22;
const char *ssid = "TESTMS";
const char *password = "autobus2020";
IPAddress server(192, 168, 10, 20);
long reading;
HX711 htu = HX711();
void TaskBlink(void *pvParameters);
void doServer(void *pvParameters);
void doMeasure(void *pvParameters);
void setup() {
Serial.begin(115200);
htu.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);
if (!htu.is_ready()) {
Serial.println("Couldn't find sensor!");
while (1)
;
}
xTaskCreatePinnedToCore(TaskBlink, "TaskBlink", 1024, NULL, configMAX_PRIORITIES - 3, NULL, ARDUINO_RUNNING_CORE);
xTaskCreatePinnedToCore(doMeasure, "doMeasure", 8192, NULL, configMAX_PRIORITIES - 2, NULL, ARDUINO_RUNNING_CORE);
xTaskCreatePinnedToCore(doServer, "doServer", 8192, NULL, configMAX_PRIORITIES - 1, NULL, ARDUINO_RUNNING_CORE);
}
void loop() {
vTaskDelay(1000);
}
void TaskBlink(void *pvParameters) {
(void)pvParameters;
pinMode(LOADCELL_SCK_PIN, OUTPUT);
pinMode(LOADCELL_DOUT_PIN, INPUT);
for (;
{
digitalWrite(LOADCELL_SCK_PIN, HIGH);
vTaskDelay(10);
Serial.print("mereni: ");
Serial.println(reading);
digitalWrite(LOADCELL_SCK_PIN, LOW);
vTaskDelay(490);
}
}
void doMeasure(void *pvParameters) {
(void)pvParameters;
for (; {
reading = htu.read();
vTaskDelay(1000);
}
}
void doServer(void *pvParameters) {
(void)pvParameters;
for (; {
vTaskDelay(100);
}
}
