# Sharp Memory LCD Kernel Driver
|
|
|
|
DRM kernel driver for 2.7" 400x240 Sharp memory LCD panel.
|
|
|
|
## Cleaning old drivers
|
|
|
|
The `bbqX0kbd` driver has been renamed to `beepy-kbd`, and `sharp` to `sharp-drm`.
|
|
|
|
Driver packages will detect if one of these old modules is installed and cancel installation of the package.
|
|
|
|
Remove the following files:
|
|
|
|
* `/lib/modules/<uname>/extra/bbqX0kbd.ko*`
|
|
* `/lib/modules/<uname>/extra/sharp.ko*`
|
|
* `/boot/overlays/i2c-bbqX0kbd.dtbo`
|
|
* `/boot/overlays/sharp.dtbo`
|
|
|
|
Rebuild the module list:
|
|
|
|
* `depmod -a`
|
|
|
|
Remove the following lines from `/boot/config.txt`:
|
|
|
|
* `dtoverlay=bbqX0kbd,irq_pin=4`
|
|
* `dtoverlay=sharp`
|
|
|
|
Remove the following lines from `/etc/modules`:
|
|
|
|
* `bbqX0kbd`
|
|
* `sharp`
|
|
|
|
## Installation
|
|
|
|
Install the Linux kernel headers
|
|
|
|
sudo apt-get install raspberrypi-kernel-headers
|
|
|
|
|
|
To build, install, and enable the kernel module:
|
|
|
|
make
|
|
sudo make install
|
|
|
|
To remove:
|
|
|
|
sudo make uninstall
|
|
|
|
