I’ve been playing around with some SCI devices (memory chips) lately and managed to actually get them working by using switches and buttons. So then I decided to see what other SCI devices I have that I can play with like that. I dug a couple nRF24 boards I own out of the parts box and looked up the data sheet. I didn’t see anything in the timing tables about a maximum pulse width on the nRF24 control inputs, which raises some questions.

Can I communicate with the nRF24 by using buttons and switches like I did the memory chips? If so, where would I start with testing? I’ll need to set one up to send data and one to receive. And if I feel evil enough to myself, I might try to interface it to my 8-bit computer.

I can’t edit (or can’t find the way to) the OP, but I meant SPI and not SCI.
