How often does this bug occurs?
always
Expected behavior
条件:使用sc031gs trigger mode,当trigger信号发起之后,调用esp_camera_fb_get()可以获取该trigger时刻的图像
Actual behavior (suspected bug)
条件:使用sc031gs trigger mode,当trigger信号发起之后,按理说调用esp_camera_fb_get()可以获取trigger时刻的图像,但是发现获取到的图像是上一次trigger时刻的图像。
主控模组:esp32s3
第一次发起trigger之后,调用esp_camera_fb_get()没有图像,第二次发起trigger之后,调用esp_camera_fb_get可以获取图像,但是是第一次trigger时刻的图像,第三次发起trigger之后,调用esp_camera_fb_get可以获取图像,但是是第二次trigger时刻的图像..........esp_camera_fb_get获取到的永远是上一次trigger的图像

Steps to reproduce the behavior
主控模组:esp32s3 使用sc031gs trigger mode
camera配置如下:
static camera_config_t camera_config = {
.pin_pwdn = CAM_PIN_PWDN,
.pin_reset = CAM_PIN_RESET,
.pin_xclk = CAM_PIN_XCLK,
.pin_sscb_sda = CAM_PIN_SIOD,
.pin_sscb_scl = CAM_PIN_SIOC,
.pin_d7 = CAM_PIN_D7,
.pin_d6 = CAM_PIN_D6,
.pin_d5 = CAM_PIN_D5,
.pin_d4 = CAM_PIN_D4,
.pin_d3 = CAM_PIN_D3,
.pin_d2 = CAM_PIN_D2,
.pin_d1 = CAM_PIN_D1,
.pin_d0 = CAM_PIN_D0,
.pin_vsync = CAM_PIN_VSYNC,
.pin_href = CAM_PIN_HREF,
.pin_pclk = CAM_PIN_PCLK,
//XCLK 6MHz for sc031gs
.xclk_freq_hz = 6000000,
.ledc_timer = LEDC_TIMER_0,
.ledc_channel = LEDC_CHANNEL_0,
.pixel_format = PIXFORMAT_GRAYSCALE, //YUV422,GRAYSCALE,RGB565,JPEG
.frame_size = FRAMESIZE_VGA, //QQVGA-UXGA Do not use sizes above QVGA when not JPEG
// .jpeg_quality = 12, //0-63 lower number means higher quality
.fb_count = 3, //if more than one, i2s runs in continuous mode. Use only with JPEG
.fb_location = CAMERA_FB_IN_PSRAM,
.grab_mode = CAMERA_GRAB_LATEST,
};
1、第一次发起trigger之后,调用esp_camera_fb_get()没有图像;
2、第二次发起trigger之后,调用esp_camera_fb_get可以获取图像,但是是第一次trigger时刻的图像;
3、第三次发起trigger之后,调用esp_camera_fb_get可以获取图像,但是是第二次trigger时刻的图像..........
esp_camera_fb_get获取到的永远是上一次trigger的图像
