I'm working with the ESP32-CAM for recognizing QR codes.
Am unable to access and see your code but from your question you can use the code below:
#include <HardwareSerial.h>
#include <Wire.h>
#include "esp_camera.h"
#include "QR_Code.h"
HardwareSerial MySerial(2); // Use Serial2 for SBUS
void setup() {
Serial.begin(115200);
MySerial.begin(100000, SERIAL_8E2, RX2, TX2); // Initialize SBUS with appropriate baud rate and pins
// Camera initialization code
camera_config_t config;
config.ledc_channel = LEDC_CHANNEL_0;
config.ledc_timer = LEDC_TIMER_0;
config.pin_d0 = Y2_GPIO_NUM;
config.pin_d1 = Y3_GPIO_NUM;
config.pin_d2 = Y4_GPIO_NUM;
config.pin_d3 = Y5_GPIO_NUM;
config.pin_d4 = Y6_GPIO_NUM;
config.pin_d5 = Y7_GPIO_NUM;
config.pin_d6 = Y8_GPIO_NUM;
config.pin_d7 = Y9_GPIO_NUM;
config.pin_xclk = XCLK_GPIO_NUM;
config.pin_pclk = PCLK_GPIO_NUM;
config.pin_vsync = VSYNC_GPIO_NUM;
config.pin_href = HREF_GPIO_NUM;
config.pin_sscb_sda = SIOD_GPIO_NUM;
config.pin_sscb_scl = SIOC_GPIO_NUM;
config.pin_pwdn = PWDN_GPIO_NUM;
config.pin_reset = RESET_GPIO_NUM;
config.xclk_freq_hz = 20000000;
config.pixel_format = PIXFORMAT_JPEG;
if (psramFound()) {
config.frame_size = FRAMESIZE_UXGA;
config.jpeg_quality = 10;
config.fb_count = 2;
} else {
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 12;
config.fb_count = 1;
}
// Initialize the camera
esp_err_t err = esp_camera_init(&config);
if (err != ESP_OK) {
Serial.printf("Camera init failed with error 0x%x", err);
return;
}
// QR Code recognition setup
// ...
}
void loop() {
// QR Code recognition logic
// ...
// SBUS communication logic
if (MySerial.available()) {
// Read and transmit SBUS data
while (MySerial.available()) {
int incomingByte = MySerial.read();
// Process SBUS data
}
}
// Attach your code logic here
}
This only works if you use the hardware esp32 ports instead of the software
