how to interface 4 bit lcd with 16 mhz crystal using avr

[amu_bgr]

with mikroelectronika easy avr board i am able to write lcd in 4 bit mode.but the same code is not working in circuit made in vero board. the hardware connection is same only difference is that i am using 16mhz crstal in vero board. is the library work for 16mhz clock.

Hi,

The library will surely work with the 16 MHz, I guess there are some hardware issues or Lcd connections declarations in the code.

i forget to mention that i am using 16mhz crystal(not oscilator) but in my dev board it is 8mhz external oscilator.

Hi,

Please, can you try changing the 16 MHz crystal with the 8 MHz and select the appropriate oscillator setting in the Edit Project window (External crystal)?
