Using SmartDMA to implement camera interface in MCXN236. This demo introduces a parallel interface for the camera solution for MCXN236.
The camera interface can be used as important part of camera usage as below:
• Object detection
• Gesture recognition
• Color recognition
• QR code scanning, and so on.
Supported formats (8-bit): RGB565
• Maximum image transfer rate: 30 fps for QVGA(320 × 240). For small RAM parts, reduce the size of image and frame rate.
• Camera module tested: OV7670
• Other camera modules can be supported as long as they provide the same signal timing.
- MCUXpresso IDE V11.9.0 or later.
- SDK_2_14_0_FRDM-MCXN236
