twr-lcd start address

ankurchauhan · ‎09-12-2015

I'm using k70 tower board with twr-lcd (using flexbus ). flexbus dc address is 0x60000000 and flexbus base address is 0x60010000.

I'm writing command to dc address and data to base address. is it ok??

or is there any other specific lcd address where we have to write the data.

or any sample code for flex bus 8 bit data transfer(character values not image) to lcd.

Regards

Hello Ankur,

You can have a look to eGUI graphic library

TWR-K60 examples use Flexbus with the TWR-LCD. You can port the code to K70.

CS is configured as you said:

#define D4DLCD_FLEX_BASE_ADDRESS 0x60010000

#define D4DLCD_FLEX_DC_ADDRESS 0x60000000

#define D4DLCD_FLEX_ADRESS_MASK 0x00010000

So you can write to data/command with the bit ‘x' 000x 0000 0000 0000 0000 , that is the bit 16 in the address.

If you look at the schematic (TWR-LCD) DC is connected to AD16, as expected.
