Raspberry Pi and ILI9341 2.8 inch SPI 320 by 240 LCD

Over the holiday weekend I finished up writing my code for this 2.8 inch LCD.  It can now do bmp graphics as well as text and even large text.  All of the code is written in Python, so there are no dependencies except for SPI support that is now built into the Raspberry Pi operating system.

This picture shows a sample of the text.  It supports colors as two sizes of text.

This is the wiring chart:

LCD	Raspberry Pi
1 – Vcc	Pin 1
2 - Gnd	Pin 6
3 - CS	Pin 24/GPIO8/CE0
4 – RST	Pin 18/GPIO24
5 – D/C	Pin 16/GPIO23
6 – SDI/MOSI	Pin 19/GPIO10/MOSI
7 – SCK	Pin 23/GPIO11/SCLK
8 – LCD	10 ohms to Vcc
9 – SDO/MISO	NC
10-14	NC

This is the code to display the bmp graphics:

def Image (filename):

  Write_CD (( 0X2A, 0X00, 0X00, 0X00, 0XEf )) #240 Columns

  Write_CD (( 0X2B, 0X00, 0X00, 0X01, 0X3F )) #320 rows

  Write_cmd ( 0X2C ) # Next: red, Green, Blue bytes

  GPIO.output (RS, True )  # RS = 1 will send data

  try:  # Prevents crashing when images do not work

    with open(filename, 'rb') as bitmap: # Must be 240x240-320 image

      for x in range ( 0,320 ):

        pixline = []

        for y in range ( 0,720 ):   # 720=240*3

          bitmap.seek(0x36 + x*720 + (719-y)) # 36 is header size

          Pixel = ord(bitmap.read(1)) # 719-y reverses image horizontally

          pixline.append (Pixel)

        spi.writebytes (pixline)

  except:

      pass

Here is a video of it running.
