In my project, I need to connect a multitude of sensors and send data wirelessly.
It’s not a problem to connect and service 64 reed switches to Arduino NANO via Shift-in 74HC165 by MISO (I didn’t find a way on the Internet except MISO).
It is not a problem to connect the nRF24L01 module to NANO - but also according to the MISO (there is no other way either).
How to solve the problem. To one, Nano connected a board with eight 74HC165, another to the nRF24L01 module, and both together on the serial.
As if there is a bitBangedSPI library, but Arduino, as it were, would not recognize it (or the hands are crooked), and I didn’t make friends with it ( disassemble into pieces).
Whoever solved such a problem (or maybe nonsense)?
