i’m trying to test out the arducam mega 3mp with this library

I tried running a project like the sample just to play with the functionality but it gets stuck inside  
saveJPG() function.

it looks like the following code never changes the received length never gets updated from the read\_byte function.  
image\_data\_next = self.\_read\_byte()  
image\_data\_next\_int = int.from\_bytes(image\_data\_next, 1)

# TODO: CHANGE TO READ n BYTES

anyone have these issues as well or some guidance?

Hi Kevin,

Welcome to the forum!

Would it be possible to send through a photo of how you have everything connected?

Would it be possible to send through a link to the dev board you are using as well?

It sounds like the pins might have to be respecified

I am using an esp32-wroom  
[https://images.app.goo.gl/SrQ4qw89cQuXAAcU9](https://images.app.goo.gl/SrQ4qw89cQuXAAcU9)  
I have changed the pinout to reflect the ESP-32 pins.

Hi Kevin,

Would it be possible to send through a photo and your code?  
I’ve had success using the driver with an ESP32 S3.

Do you have it wired to 3.3V power?

Hey @Kevin289087,

Thanks for sending through that code! As Liam mentioned above, it would be super helpful if you could provide **a photo of your physical wiring and connections**! This can typically reveal various bits of info that are easy to miss.
