 Here I want to tell you quickly how to make it possible to connect an 7Fets attached to an other 7Fets connected to a raspberry Pi.
 When you connect a device on SPI0 and and you scan:

 You maybe be asking why it is 0x48, while you can see it in the [[default addresses]] as 0x90.
-That is because it is getting divided by 2. So: 0x90/2=0x48. If you are getting confused it is 0x48 and not 0x45, because it is in hexadecimals.

 You will see:

-(If you use i2c you have to do:
- i2cdetect -y 1
-)
 This is something you don't want, because now he only sees 1 7FETs. And with the car you of course want to make it possible to let the car drive different directions.
