Chip Select vs Chip Enable on SPI bus.

Projects Networking, Protocols, and Devices

Hi all!,
I'm connecting, by SPI bus, a TFT and a nRF24L01+ on a Nodemcu board.

The TFT is on pins (and works properly):
D3.............TFT RS
D4.............TFT RST
D5.............TFT CLK
D7.............TFT SDA
D8.............TFT CS

Does the TFT has a Chip Enable??

How can I connect the nRF24L01+??

Thanks in advance!

Chip Select and Chip Enable mean the same thing. The pin is set LOW to communicate with just that device.
