Quick Start Guide for the OV7740

component.

This is the quick start guide for the ov7740_sensor_group, with step-by-step instructions on how to configure and use the driver for a specific use case. The code examples can be copied into e.g the main application loop or any other function that will need to control the OV7740 CMOS image sensor.

Use cases

ov7740 basic usage

This use case will demonstrate how to initialize the OV7740 sensor module.

Setup steps

Prerequisites

This module requires the following driver

  • group_sam_pio_capture

ov7740_basic_usage_code

If the OV7740 is clocked using Peripheral Clock, the according PLL must be configured to ouput the right frequency on the given PCK pin. If the microcontroller has at least two PLL, another PLL can be used to clock the system at different frequency. Then the OV7740 can be configured according to the system requirements.

Other external components, like SRAM/SDRAM have to be configured also with correct SMC settings.

Finally, the PIO capture mode has to be configured for acquisition.
