Re: Should f_findfirst be available when the define FF_USE_FIND is set?

Thought I'd have another go at this so I pasted the contents of the IDF release 3.3.2 to C:\Users\Dude\Documents\ArduinoData\packages\esp32\hardware\esp32\1.0.4\tools\sdk\include\fatfs and edited the config to allow f_find commands Now it compiles but it crashes at line fr = f_findfirst(... From the...

Re: Measuring the distance to a detected face

OK... got confused between focal length and view angle on the lens. Focal length appears to be 3.6 on the camera so calculation code is: int eq_top = 3.6 * 200 * 240; // f(mm) x real height(mm) x image height(px) int eq_bottom = smoothed_face_height * 2.7; //object height(px) x sensor height(mm) int...

Re: Does ADF only work with the development boards

Thanks for the tip. Looking at the example I then worked out how to convert the http_mp3 example to play through an amp and speakers connected to the ESP32 pins. I sort of also got it working with Icecast and SAM cast to run something on the internal Wi-Fi. Some more questions if you have time: Is i...

Does ADF only work with the development boards

Quick question.. does the ADF only work with the development boards mentioned in the ADF readme?

I just want to experiment with a simple stream player on a normal ESP32 board.

Measuring the distance to a detected face

I'm trying to calculate the distance to a detected face using the measurements from the net_boxes array. I found this calculation from https://photo.stackexchange.com/questions/12434/how-do-i-calculate-the-distance-of-an-object-in-a-photo https://i.stack.imgur.com/ajKph.png Using the measurements: F...

Re: ESP-EYE recognization without web streaming!!!

I have a tutorial here: https://robotzero.one/esp32-face-door-entry/ that does face recognition without a web browser being connected. I'm not sure this one works with the current ESP32 hardware library for Arduino. Probably this part needs updating: mtmn_config_t init_config() {.... You might find ...

Re: Cmake not working with ESP-WHO project?

Not sure if it's the same problem but I got the camera_web_server example to build using the following two settings in menuconfig

Partition Table > Partition Table (Single factory app, no OTA)
Partition Table > (0x10000) Offset of partition table

Closing a Bluetooth connection that hasn't been used.

I'm using serial Bluetooth so a user can set Wi-Fi details and read the IP address from a phone. I want to kill the Bluetooth connection when either: a) The details have been entered correctly (via Bluetooth) b) The device restarts and the user has viewed the IP address on their phone (via Bluetooth...
