First I'm checking if the hardware works. So I am using the Demo of ArduCAM.
when I use this code give me a error that OV2640 was not declared in the scope. So I change to 5 and works.
I don't no why when I take a picture the sd card give me a empty file.
Hardware:
OV2640
Arducam-f rev.c
Uno r3
I'm automating a table of noughts and crosses. For this I use a camera to identify the positions through the analysis of colors. Communicate with HMI and HMI with PLC
My problem is resolved.
But I need to use a ethernet shield between arducam and uno. When I assembly it the program doesn´t work. Can be some communication problem because ethernet shield??
