The LED examples for MikroBASIC work fine, the glcd doesn't.

[Sirchip]

I have the "EasyAVR4" development board.

I have the latest version of MikroBASIC installed. The LED_blinking, and LED_curtain tests worked fine.

For testing of the large graphical LCD display I tried the following example test: glcd_test.abap. This test was created on Thursday, September 28, 2006.

When building and running the test the AVRFLASH programmer Loaded and wrote the program to Flash memory properly, there were no errors.
The glcd did not show anything. The display is lit properly, the changeable pin is in the graphical pin position. The contrast control works fine and does adjust the contrast. I tried all different positions for the contrast control, but still no graphical characters were viewed during multiple, attempted, glcd_test.abap tests. The glcd is properly mounted on the pins and socket assembly.

I sure would like to see something on the glcd. Please give me some ideas. Thank you.--Mike

Mike,

I also have a similar problem but with PIC microcontrollers. The LED is blinking fine. But when I include the glcd_init line below

T6963C_init(240, 128, 8, PORTD, PORTA, 3, 2, 0, 1)

the whole program compiles but the LED blinking is also stopped. Nothing comes to the GLCD either. Did you get any feedback ?

Thanks
Kamal

Hi Mike,

Here is the code that should work with EasyAVR4 and ATMEGA16:

Code: Select all

'* Project name:
'     graphical LCD test
'* Author:
'     MikroElektronika, July 2006.
' * Description:
'     This program demonstrates how to use GLCD library. This example is writing
'     images, text, lines, rectangle, boxes, cycles and more.
' * Test configuration:
'     MCU:             ATmega16
'     Dev.Board:       Easy AVR 4
