ESP32-CAM only saves in FRAMESIZE_CIF
Posted: Mon Aug 24, 2020 10:59 pm
Hi everyone, first post here.
It's my first experience with ESP32-CAM and I started from some sample code found online. In particular, I use this snippet to configure the camera:
Unfortunately, I'm only getting FRAMESIZE_CIF pictures.
I'm using an ESP32-CAM module by DIY STORE. On the back, it says "ESP32-S". Is it a problem with the code or a limit of the dev board?
Thank you.
It's my first experience with ESP32-CAM and I started from some sample code found online. In particular, I use this snippet to configure the camera:
Code: Select all
// camera config
camera_config_t config;
config.ledc_channel = LEDC_CHANNEL_0;
config.ledc_timer = LEDC_TIMER_0;
config.pin_d0 = Y2_GPIO_NUM;

config.pin_reset = RESET_GPIO_NUM;
config.xclk_freq_hz = 20000000;
config.pixel_format = PIXFORMAT_JPEG;
// init with high specs to pre-allocate larger buffers
if(psramFound()){
config.frame_size = FRAMESIZE_SVGA;
config.jpeg_quality = 10; //0-63 lower number means higher quality
config.fb_count = 2;
} else {
config.frame_size = FRAMESIZE_CIF;
config.jpeg_quality = 12; //0-63 lower number means higher quality
config.fb_count = 1;
}
// camera init
esp_err_t err = esp_camera_init(&config);
if (err != ESP_OK) {
Serial.printf("Camera init failed with error 0x%x", err);
delay(1000);
ESP.restart();
}
