Arduino/ESP8266 version

[benkuper]

Hello,
good motivation for this research, many people are interested in this i'm sure !
A lot of websites mentionning your article and your research are talking about an Arduino/ESP8266 library.
In your article, you struck out the "Arduino/ESP" part and replaced it by "Teensy", which i guess is for processing / sensing speed necessity for the photodiode, but since there is no precision, here is my question :
Why the use of a Teensy over an Arduino or ESP8266 (which i think is as fast as a Teensy) ?
Do you think it is theorically possible to get something working with an ESP ?

Thanks and congrats,
Ben

I believe this is to use the "FlexTimer" Timer Input Capture of the Teensy on multiple pins.
The ESP8266 does not seem to be capable of that.
But there's currently an attempt at repurposing the I2S bus of the ESP8266 on one pin to circumvent the lack of FlexTimer and read data from one sensor:

Interesting, thanks for the link !
Actually, it may be more relevant now to use the later ESP32, it might solve some problems.
