详细描述

GC2145 sensor driver.

Register tables and control logic adapted from esp32-camera's gc2145.c (Apache-2.0). The GC2145 has no JPEG encoder, so set_pixformat(PIXFORMAT_JPEG) always fails; the core also rejects it up front via camera_sensor_info_t.support_jpeg.

Framesize scaling uses the subsample strategy (esp32-camera's Kconfig default, CONFIG_GC_SENSOR_SUBSAMPLE_MODE): keep the widest field of view and pick the coarsest subsample ratio that still covers the requested window.

函数说明

gc2145_detect()

int gc2145_detect

(

sensor_t *

sensor

)

返回

0 if detected

gc2145_init_sensor()

int gc2145_init_sensor

(

sensor_t *

sensor

)

Fill sensor_t function pointers and write the default register set.

返回

0 on success
