Re: ADuC702x with uc1601 LCD controller via I2C

...continued...

The attempt to rewrite the uc1601s module was unsuccessful.

(See the whole project in attachment).

I make it without clear comprehension, and as result - it doesn't operate correctly.

Please, explain me

what manner must I make the correct transmission.

For example:

void uc1601s_config(void)     //This is initializing routine

// for uc1601s controller

{

          i2c_start();

          i2c_write(0x70);

          i2c_write(0xE8); // Set LCD Bias Ratio - 6

   i2c_write(0x81);  // Set Vbias Potentiometer

   i2c_write(0xD0);          // RDX0154

   i2c_stop();

   i2c_start();

   i2c_write(0x70);

   i2c_write(0x40);  // Scroll Line - OFF

   i2c_stop();

   i2c_start();

   i2c_write(0x70);

   i2c_write(0x89);  // Set RAM Address Control

   i2c_stop();

   i2c_start();

   i2c_write(0x70);

   i2c_write(0x84);  // Disable Partial Display

   i2c_stop();

   i2c_start();

   i2c_write(0x70);

   i2c_write(0xC2);          // Set LCD Mapping Control -

   i2c_stop();

   i2c_start();

   i2c_write(0x70);

   i2c_write(0xAF);  // Set Display Enable

   i2c_stop();

}

First of all I can't understand how to shape the START, RESTART and STOP  i2c  conditions.

Please help!
