Wiring diagram for Pi B and RA8875???
Googled the heck out of it and find lots of hey wow i got this working but not a single hint as to correct wiring... :(

Re: Wiring diagram for Pi B and RA8875???
The RA8875 is just SPI, plus a reset line and an interrupt line. Whatever Pi solutions you find would have their own wiring assignments - there's no general guideline I can give you. We don't have any tutorials or support for the RA8875 on the Pi.

Re: Wiring diagram for Pi B and RA8875???
Ok could some one maybe guide my hand just a hair, I think I have worked out some of the wiring. If i get this working correctly I will gladly take pics and post the diagram, as well as the modified drivers.
eg. RA8875 to Pi
o VIN = ?
o GND = Pin 6
o 3Vo = ? (I think Pin 1)
o LITE = N/A
o SCK = ?
o MISO = Pin 21
o MOSI = Pin 19
o CS = Pin 10?
o RST = Pin 9?
o WAIT = N/A
o INT = Pin 3?
o Y+ = ?
o Y- = ?
o X- = ?
o X+ = ?

VIN - 3.3V (pin 1)
GND - GND (Pin 6)
MISO - MISO(pin 21)
MOSI - MOSI (pin 19)
SCK - CLK (pin 23)
CS - CE0 (pin 24)
RST - any available GPIO pin
INT - any available GPIO pin.
GND - GND (Pin 6)
MISO - MISO(pin 21)
MOSI - MOSI (pin 19)
SCK - CLK (pin 23)
CS - CE0 (pin 24)
RST - any available GPIO pin
INT - any available GPIO pin.

Will give that a try, wish me luck, once i have that setup i will start a port of the drivers. If all is well I will post results with pics and links to how it was done up.
Edit: Also where did you get the info you drew this from so i can read up and ask less next time?
