Well,  the datasheet shows you all the commands.   Just bit-bash it.

When you have it running with bit-bashed code I would experiment with regular SPI.   
e.g. send 0b00000101 after /CS becomes active.
the chip might just skip the leading zeros and respond to the first 1 bit.  i.e. 0b101

What are you going to use it for?

David.

No.   I do not have your LCD.
If and when I install a petrol pump in my front garden,   I will write any software that might be required.

If you are running a commercial garage / filling station your equipment will have to be approved by your country's Trading Standards.

I doubt if many multi-million dollar companies rely on Arduinos
Or if an Arduino hobbyist would trust filling their car in an unapproved Filling Station.
They would be paying good money (and taxes) for an unknown quantity of petrol.
