Hi there,
GPIO module coming with nodeMCU is limited to 13 values (0-12). However there are interesting possibilities to use more GPIOs. For instance, Pins 21 and 22 (UART RX and TX) can be used for I2C. So why to spend not so long list of GPIOs?
I wonder if the source of GPIO module is open. So I could expand the range of usable IOs.
Looked at github but can't find the source.
Thanks for help.
