Nokia 2300-rm4-Schematics

The Nokia 2300 is a very basic phone. The display is black and white with very low resolution, and there are few features. A radio is included, but it is mono only. One of the biggest problems with the 2300 is the weird keypad design that uses joined-up and overlapping keys. Not easy to use, not very reliable, and not recommended!
Actually the Nokia 2300 mobile phone is owned by my wife. I bought it as a birthday present for her. The result, I got more time to get hold of the phone to observed and have reviewed it. SMS upgrade has gone too far these days especially with Nokia phones. Superb audio quality can be expected from this phone. I like the way the polyphonic ringing tone sounds of this phone. They're distinctive and clear. You can download or compose melodies as well. The FM stereo radio is excellent. A stereo headset comes with the package, great for hands-free calls and music listening! I have no problem with the reception; it's always in full bars wherever I go. Just one or two keypresses and you can have the function you need. Of course not all functions, menus, and sub-menus are available in this feature. We all know that phones are getting smarter and smarter these days. And someday the function we thought just another trash of today, will one day just useful as technology advances and that would be also added in this feature. Over-all, the phone is a great improvement intended for low-end-users. If picture editor feature has been added in this phone, then it would surely surpass the performance of Nokia 33XX series, 2100, and 1100 phones respectively.

Nokia 3310 LCD Interfacing

In this tutorial we will interface Nokia 3310 LCD with AT89C51.The Nokia 3310 LCD is based on a PCD8544 48x84 pixels matrix LCD controller.

Pin Diagram

Circuit Diagram

NOTE:Nokia 3310 LCD works on voltage level of 3.3v.To get this voltage level 10K resistor array, LED, diodes are used.

Few details

Display Data RAM (DDRAM)

The DDRAM is a 48x84 bit static RAM which stores the display data. The RAM is divided into six banks of 84 bytes (6x8x84 bits). During RAM access, data is transferred to the RAM through the serial interface. There is a direct correspondence between the X-address and the column output number.

Addressing

The columns are addressed by the address pointer. The address ranges are:

X 0 to 83 (1010011)

Y 0 to 5 (101)

Addresses outside these ranges are not allowed.

Horizontal addressing mode:

In the horizontal addressing mode, the X address increments after each byte. After the last X address (X = 83), X wraps around to 0 and Y increments to address the next row. After the very last address (X = 83 and Y = 5), the address pointers wrap around to address (X = 0 and Y = 0).

Lcd command list

21H: Activate Chip and H=1.

90H: Set Vop voltage (contrast)

13H: Adjust voltage bias.

20H: Horizontal addressing and H=0

09H: Activate all segments.

08H: Blank the Display.

0CH: Display Normal.

0DH: Inverse video mode

Y-ram address: 40H or (y and 07H)

X-ram address: 80H or (y and 7FH)

Serial Bus Protocol

Serial interface maximum 4.0 Mbits/s

The MSB of a byte is transmitted first.

The serial interface is initialized when SCE is HIGH. In this state, SCLK clock pulses have no effect and no power is consumed by the serial interface.

A negative edge on SCE enables the serial interface and indicates the start of a data transmission.

SDIN is sampled at the positive edge of SCLK. The level of the D/C signal is read during the last bit of data byte.

Convert BMP to HEX

1. Create bitmap image using MS Paint.

2. Go to Image/Attribute option

Set width: 88 and height: 48

Select unit: Pixels color: Black and white

3. Invert color

4. Rotate 270 degree.

5. Save as image.bmp

6. In command prompt go to directory where z_bmptohex.exe is saved.

7. In command prompt type z_bmptohex image.bmp

8. You will see that image_bmp.inc file is created having hex array of [88] [6]

9. Open image_bmp.inc file in notepad and delete first four rows of array so that you get [84] [6] matrix.

10. Copy this array and convert this file according to your assembler syntax and paste into your main program code.
