| Feb 20, 2020 at 7:41 | comment | added | ShoutOutAndCalculate | @StarCat Thanks! So I won't need to do the pull up resistor on ESP 32 like that of ESP 8266 right? | |
| Feb 20, 2020 at 7:30 | comment | added | StarCat | @ShoutOutAndCalculate, The ESP32 has hardware support for I2C so should be able to run faster. | |

| Feb 19, 2020 at 21:51 | comment | added | StarCat | It depends on what the script is doing. In practice the ESP8266 will almost always be faster. An exception might be I2C (the Wire library, like in your test). The Arduino Nano AVR processor has hardware support for I2C; the ESP8266 must use the much slower “bit banging” method. | |
