Please run wires between the slave and master to make the example function
(pins are the same for the host and the slave):

CLK GPIO14
CMD GPIO15
DAT0 GPIO2
DAT1 GPIO4
DAT2 GPIO12
DAT3 GPIO13
Ground GND
======== =========
| Signal | GPIO NUM |
|--------|----------|
| CLK | GPIO-14 |

CMD and DAT0-3 lines require to be pulled up by 50KOhm resistors even in
1-bit mode. See *Board Compability* below for details. In 1-bit mode, the
