First B4r project

[Star-Dust]

Yesterday I received an ESP32 microcontroller and I started testing it.
My wish is to port my 3D graphics library to the microcontroller with a display. But at the moment it seems like too daring a goal for my very little knowledge of B4R.

So I started with a simple project, creating an http server. Well after a few hours of banging my head to understand how to configure B4r and have the device recognized and that the debugging is very poor, I understand that there are no classes, lists, maps, that the functions only return basic data, the strings do not they are concatenated with neither with -& nor with +, that there are no services and that the types cannot contain objects, or at least if they contain them they do not work correctly....

I produced my first server... still in its infancy

I hope the http server library will be available for the community soon.

I don't know, it's very complicated with few tools available and also little time... but something will emerge sooner or later

Deep dive directly. I would prefer step by step. Congratulations.

Have a look at this - there could be a possibility here UI Designer

I mix inline C with B4R (and I hate C since the 80ies). So I can try out fancy stuff from other GitHubs

 

[Star-Dust]

I did a new experiment.

I used esp32 as the license key for my software. The software checks if there is an esp32 connected to the USB port and queries it, if the codes it receives are validated it starts the software.

It seems to work

Something like this would be ideal for that
ATTINY85 Digispark - plugs straight into a usb port

It looks excellent for the small size. I have to find a box case

Look at these guys as well: Seeed Studio XAIO

Basic debugging for all microprocessors (with breakpoints and variables viewing) can be achieved with the rDebug library (check B4R libraries in my contributions in my signature).

Are you using the ESP32 wired to the host USB port?
Why not use the USB wireless (wifi or bluetooth) in AP mode, and the host app would try to first scan it to see if the correct "dongle" was in range...
It's a cool idea!

 

[Cableguy]

As for the HTTP server... the greatest advantage of B4X is that you can tailor any solution to your needs....
The remote configuration example makes use of HTTP SET/POST, so you can create a code module and create your own http "server"

Yes, I preferred USB because with WIFI I don't know which network it is on and I would have to configure the SSID and Pass each time

you could use wifi-direct and start the ESP32 in AP mode, so i'ts SSID and Password are always known (since you are setting them in your code)
You would need to power it somehow, though
