Karthi Keyan,

Actually we released the new TMS320F2812 Development kit with most of interfacing, if you willing to purchase a new kit for your project kindly refer the below link:

if not ready to purchase. No issues am ready to help with your PS-TYRO-TMS320F2812 DSC kit.

Actually LCD can able to interface with 8-bit mode or 4-bit mode,

For 8-bit mode totally 8 Data Lines and three Control lines are required.
For 4-bit mode totally 4 Data Lines and three Control lines are required.
(it's your choice depend upon the lines available)

In our TMS320F2812 DSC kit , we terminated these 4 expansion connector PORTA, PORTB, PORTD/E/G, PORTF for user purpose from this you may choose any port. kindly let me know what is your project and the pins you are used for your project then i guide you.

Karthi Keyan,

I worked for you and am back with content for you. according to your project you are using PORT B Connector (i.e, Event Manager B you are using to generate the 6 PWM ).From the remaining port. I suggest you to choose the PORT A lines to interface 16x2 AlphaNumeric LCD.

The detailed Schematics logic is drawn and attached for you and i also i done the C Coding for you. Find the attachment please.

Schematics Details:
The VEE pin of LCD - Connect Variable resistor with 3.3v and Gnd (Tune for Contrast)
The VCC pin of LCD - Connect the 5V.
The GND pin of LCD - Connect the GND
Remaining pins of LCD are connected to the PORT A lines accordingly.

This Schematic and C coding for LCD Interfacing is verified with PS-TYRO-TMS320F2812 DSC kit. After Implementing this please let me know your status.
