Detailed Description

GC032A sensor driver.

Register tables and control logic adapted from esp32-camera's gc032a.c (Apache-2.0). The GC032A 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 windowing: crop the requested window out of the full VGA frame (esp32-camera's gc032a.c has no subsample mode).

Function Documentation

◆ gc032a_detect()

int gc032a_detect ( sensor_t * sensor )

Probe the bus for a GC032A. On success fills sensor->id.

Returns: 0 if detected

◆ gc032a_init_sensor()

int gc032a_init_sensor ( sensor_t * sensor )

Fill sensor_t function pointers and write the default register set.

Returns: 0 on success
