 # Sharp Memory LCD Kernel Driver
 
-**Note**: I did not write this driver. I only modified it to clean up compiler warnings/errors. The original can be found here:
-(http://www.librecalc.com/en/wp-content/uploads/sites/4/2014/10/sharp.c)
+DRM kernel driver for 2.7" 400x240 Sharp memory LCD panel.
 
-More information can be found here:
-(http://www.librecalc.com/en/downloads/)
+## [Original readme with pinouts and build instructions](README.orig.md)
 
-This driver is for the LS027B7DH01. It *should* work with other Sharp Mem LCD displays by modifying all 400/240 references with the correct dimensions for your screen.
+## References
 
-## Hookup Guide
-Connect the following pins:
+Original SPI and GPIO kernel driver at:
 
-Display | RasPi
-------- | ---------
-VIN     | 3.3V      
-3V3     | N/C       
-GND     | GND       
-SCLK    | 11 (SCLK) 
-MOSI    | 10 (MOSI) 
-CS      | 23        
-EXTMD   | 3.3V      
-DISP    | 24        
-EXTIN   | 25

-## Compile/Install the driver
-Verify that you have the linux kernel headers for your platform. For the RasPi these can be obtained by:
-```
-sudo apt-get install raspberrypi-kernel-headers
-```
-or more generally:
-```
-sudo apt-get install linux-headers-$(uname -r)
-```
+Sharp datasheet:
 
-To compile the driver, run:
-```
-make
-```
-
-To install the driver, run:
-```
-sudo make modules_install
-```
-
-If you want the module to load at boot you'll need to add it to the /etc/modules file, like:
-```
-...
-# This file contains...
-# at boot time...
-sharp
-```
-
-## Compile/Install the Device Tree Overlay
-The included sharp.dts file is for the Raspberry Pi Zero W. To compile it, run:
-```
-dtc -@ -I dts -O dtb -o sharp.dtbo sharp.dts
-```
-
-To load it at runtime, copy it to /boot/overlays:
-```
-sudo cp sharp.dtbo /boot/overlays
-```
-
-And then add the following line to /boot/config.txt:
-```
-dtoverlay=sharp
-```
-
-## Console on Display
-If you want the boot console to show up on the display, you'll need to append `fbcon=map:10` to /boot/cmdline.txt after *rootwait*, like:
-```
-... rootwait ... fbcon=map:10
-```
-
-To make sure the console fits on screen, uncomment the following lines in /boot/config.txt and set the resolution appropriately:
-```
-framebuffer_width=400
-framebuffer_height=240
-```
