I'm having issue with these modules "DFRobot FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi &Bluetooth) DFR0478" and the " DFRobot FireBeetle Covers-Camera&Audio Media Board DFR0498".

I download the instructions from the web https://wiki.dfrobot.com/FireBeetle_Cov ... KU_DFR0498 and the only program that will run without issues is the SD Card read/write pull off from the link you send.

Three other programs will not run:

1. Camera
2. Play list
3. Record

The error message I get is:
C:\Users\James Anderson\Documents\Arduino\libraries\DFRobot_IIS-master\camera.cpp:46:20: fatal error: ov2640.h: No such file or directory

This message appiles to 3 progarms I try to compile on the Arduino.

Please can some point in the right direction to resolve this

Many thanks

Hi James,
The official library do not contain OV2640, please kindly note it does not support it.

Thank you for the prompt reply

Where can I download the offical libary for this product FireBeetle ESP32 IOT connected to FireBeetle Covers-Camera&Audio Media Board?

Thanks

James

Just check its wiki via SKU No. and download it through the link offered in wiki.

Hi, I did down the libary and used the WIKI page instructsions still got the same problem, also the libary is the same one I used before.

I removed all referance to ov2640 in the files in the libary.

The Play and Recored worked OK, but still have this error: "E (6058) ledc: ledc_set_duty_with_hpoint(383): hpoint argument is invalid"

The Camera did not and throws up this error below:

Any more suggestion please, to clear these errors and get the camera working?

Hi James,
We have tested the library, and there is no error.
Please check the camara, whether is it connected rightly.

[james.ander]

What ESP32 did you use to test the camera
was it a DFROBOT ESP-WROOM-32 or ESPressif ESP32-WROOM-32D?

I check the connection of the camera and tested again, still got the same error as below

Hi after several tests, we found the error
"SCCB_Read [0a] failed rc=2
SCCB_Read [0b] failed rc=2
SCCB_Read [1d] failed rc=2
SCCB_Read [1c] failed rc=2"
is due to wrong camera type or broken camera or not pluged rightly.
The normal process code and wrong camera code has be shared via this link https://github.com/NanaWangDFR/DFPlayer ... camara.png and https://github.com/NanaWangDFR/DFPlayer ... Normal.png
please check it for reference.
