B4R Question ESp32 Analog Range Enhancements

[rodmcm]

Feature Request
Would it be possible some time to have the more advanced features of the ADC on the ESP32 available on B4r?
This video shows the possibilities and the very handy linearisation formula for a 0-4095 count

Of course, B4R has all the functions, since the analog converters are the same configuration as an Arduino.

Hi,
Do you have an B4R example reading ESP32 ADC pins ?
Thanks

Yes!

 

[Johan Hormaza]

These are the most common ADC pins in ESP32

 

[Johan Hormaza]

Keep in mind that the following Pins are:
Vp = pin 36
Vn = pin 39
Until pin 13 are ADC, all those pins I have tested and they work
All you have to do is change the Pin number

A0.Initialize(36,A0.MODE_INPUT)' pin ADC 35...

Here I attach this example, which also comes with an example of how to use the full ESP32 PWM. I hope and it is useful.
Any question, I will be here to order

Here is an image of ESP32 and its pins

Johan,
Great , this is going to help
Gracias , Many thanks

I'm going to hijack this thread - even though it is 2 months old.

I am starting with the ESP32 ADC. You mention "Of course, B4R had all the functions ..." referring to the YouTube video.

How would one access, for example, the AnalogSetWidth() function?

Can this be done from B4R? Is there an h file or library that must be included?

Thanks,
Barry.

Should be simple to call with inline C.

#if C
void AnalogSetWidth(B4R::Object* o) {
analogSetWidth(10); 
}
#End if

RunNative("AnalogSetWidth", Null)
