This article explains how to use the C38A camera (OV7620 CMOS sensor) with the APF9328. Alchimoun and Jmfriedt already used a similar camera and all their code is available here (documentation of their project is available here in french, starting page 17 for CMOS sensor).
Pinout
The pinout of the kit is as following :
| C38A pinout | ||||||||||||||||
| PIN | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 | 22 | 24 | 26 | 28 | 30 | 32 |
| Y1 | Y3 | Y5 | Y7 | RST | FODD | HREF | VSYN | PCLK | VCC | VCC | UV1 | UV3 | UV5 | UV7 | VTO | |
| Y0 | Y2 | Y4 | Y6 | PWDN | SDA | SCL | AGND | AGND | EXCLK | AGND | UV0 | UV2 | UV4 | UV6 | GND | |
| PIN | 1 | 3 | 5 | 7 | 9 | 11 | 13 | 15 | 17 | 19 | 21 | 23 | 25 | 27 | 29 | 31 |
Powering
The C38A is 5V powered, it's not a great problem to power the module at this voltage. But the problem is for I/O, because all APF9328 I/O are 3.3V signals. To solve this problem, the chip used in C38A provide a IO VDD power entry that can be powered with both 5V or 3.3V. By default on C38A kit, all power supplies are connected to 5V. To provide 3.3V on power IO (DOVDD):
- JP2 strap on kit must be deconnected,
- 3.3V must be connected on J6 (DOVDD)
