-
Where did you get the camera module(s)? UCtronics and ArduCAM direct
-
Model number of the product(s)? Mini 2MP plus running on a 4MHz SPI clock frequency
-
What hardware/platform were you working on? ESP32 with Platformio & Arduino IDE
-
Instructions you have followed. (link/manual/etc.) OV2640 DS and Arducam library
-
Problems you were having? Occasional miscolouration or incorrect JPG aspect ratio
-
The dmesg log from your hardware?
-
Troubleshooting attempts you’ve made? changes to programmatic timings
-
What help do you need? clarification of library/example timings chosen
The initCAM function within the library sends a software reset to the module and then has a 100mS programmatic delay. The OV2640 DS however, says that a software reset takes less than 1mS. Is there any reason for the the longer delay?
Secondly, the examples for capture perform the SPI.transfer within a while loop whilst there is data remaining. In the supplied examples there is a 15 microsecond programmatic delay before transferring the next byte… again any reason for this?
