ESP32 - Reusing example source - Esp32-Camera

[BenR]

Think the £0.73 is just for the programming interface, the complete thing is £4.40 but still a good price.

At least we know that what works for you should also work for me.

I got an IDF web cam project working with the camera which was pretty decent quality, I then maybe spent an hour trying to shoehorn that into Flowcode and then likely got distracted with something else.

Thanks - that means I don't feel so bad - I think I paid £6 including the programming extension board.

I'll post the code this evening...

I think this should do the trick...

So all the steps from the first post - except creating the fc file - use examples.fcfx from below and changes to files examples/main (these are included in the zip file..)

Extract the zip file to examples/main

Do the idf.py fullclean etc from the subsequent message.

Compile and (hopefully) should download and run (make sure there is an sd card in place!) - saving a photo every few seconds....

I've left file names as per espressif (sd_card_example_main.c for example) - but I have modified them (app_main has gone etc) - the names are a good reminder of their origin?

There is very little feedback/error checking - as mentioned I couldn't get the UART to work (and the pins A0, A3 aren't an option when using the esp32 camera board target ?)

For 'timelapse' photography - it would be good to either check if files exist or save a 'count' in eeprom, so it doesn't overwrite on power down / restart. My intention is to use deepsleep and wake every 'interval' seconds, take a snap and then sleep again.

It might be good to pull in the time/date from the web to timestamp the photos..
It should be 'fairly easy' to add a web server and transmit the image over wifi?
Can use led=0/1 to toggle the flash

Anyone (Iain/Ben?) manage to get this to compile?

I did a slightly more 'advanced' version - here it attempts to set the RTC from NTP on first run (files have timestamp) and takes a photo every 5s (change 'interval' if needed) - it uses deep sleep to try and minimise battery consumption.

You'll need to set password and ssid (in SetRTC) to connect to wifi...

Note - here I turn the flash on to take the photo - it also shows 'life'. Also that if the SD card isn't inserted it will crash and restart - flash rate is increased..

Hi

Working away at present with no access to hardware. Will try once I get back.

Regards

Thanks - will be interesting to hear how you get on....

Thanks guys, I wish everybody would share their projects like this one!

Just set this up with a 5M pixel camera. Powered by 4 x AA onto the 5V/Gnd pins and seems to work well. Takes a photo every 10s - using a class 10 micro SD card and saving as JPG (~450KB)

Have had a pair of owls in the garden and I'm hopeful Have turned the 'flash' off - to avoid alarming them, in the (very) unlikely event I get a photo..

Not with the esp32!

That is still a great picture!
