**Rotate display**
    sudo nano /boot/config.txt
Change the parameter as follow:\\
(Rotate 90)
    dtoverlay=waveshare35a -> dtoverlay=waveshare35a:rotate=180
(Rotate 180)
    dtoverlay=waveshare35a -> dtoverlay=waveshare35a:rotate=270
(Rotate 270)
    dtoverlay=waveshare35a -> dtoverlay=waveshare35a:rotate=0

**Rotate touch**
    sudo nano /etc/X11/xorg.conf.d/99-calibration.conf
Press the keyboard “Ctrl + X” ,then choice “Y”, Press the ”Enter” exit.\\
Change as follow:\\
(Rotate 90)
    Section "InputClass"
    Identifier "calibration"
    MatchProduct "ADS7846 Touchscreen"
    Option "Calibration" "3932 300 3801 294 "

Here are the steps that I took to get it working. The screen should start working at step 5 when you do the test.

1.Expand the filesystem

   sudo raspi-config

2.Change fb0 to fb1

   sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf

3.Enable SPI if needed

   # remove or comment out the spi blacklist line
   sudo nano /etc/modprobe.d/raspi-blacklist.conf

4.FBTFT drivers as loadable modules

   sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update
   sudo reboot

5.Test

   sudo modprobe flexfb  width=320  height=480  regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3
   sudo modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24

6.Perminantly add Driver

   #Add to file /etc/modules
   flexfb  width=320  height=480  regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-,0xC5,0x00,0x00,0x00,0x00,-,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3
   fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24

7.Additional settings

   #config.txt
   gpu_mem=128

   #cmdline.txt
   fbcon=map:1 fbcon=font:ProFont6x11
