Cannot compile for Heltec Wifi Kit 32

[Eddiiie]

Hello,

Today I get compile error. Can you please confirm if this lib works ok for Heltec Wifi Kit 32. Meanwhile, I will test sample code.

Thank you!

Same for board Error compiling for board "Heltec_WIFI_LoRa_32".
Expected.

Code compiles ok when selecting NodeMCU type, but will not upload obviously.

The library is written in (inline) assembly and hence does only work on the esp8266, it will not work for esp32. See also the readme here. Note that the esp32 has hardware support for i2c, thus implementing i2c in software wouldn't make much sense.

Oh, sorry about that. I am going too fast. :) ToOO many different directions at one time.
