Hi,
The LUC_lcd4busy.lib was successfully used with an ATmega48, ATmega168,
ATmega16, ATmega32, ATmega128.
* * *
Test first your LCD module with the standard routines of Bascom. (CONFIG LCDPIN = PIN ....).
When you do that, make sure the R/W pin of the LCD is permanently connected to ground.
When the LCD module works with the standard routines of Bascom, then go back
to the LUC_lcd4busy.lib and connect again the R/W line to the ATmega8.
* * *
Which version of the Bascom compiler are you using?
Best regards,
Luciano |

Mr.Luciano, I have 3 modules LCD, 2 LCD 1602A and 1 1602H.
All LCD, have been checked up on ATTyny2313 with "lcd4.lbx",
In standard for Bascom configurations. All LCD works.
p.s. I use the compiler of version 1.11.9.8
Best regards |

Try the code below.

Mr. Luciano, so too does not work.
The only thing that has changed, on LCD points, brackets and other dust
There can be you have an opportunity to test on Mega8? |

Hi,
I don't have here an ATmega 8 so today I have ordered two chips
ATmega8 an two chips ATmega8A. I will let you know the results
as soon as I receive the chips.
Best regards,
Luciano |

Hi,
Works OK here with an ATmega8. See attached pictures and attached HEX file.
Try to program your ATmega8 chip with my HEX file. If it does not work, then
verify your hardware.

Luciano

Hi,
Increase the contrast and see if the LCD is initialized for two lines or just one line.
Best regards,
Luciano |

Second line not work.
Tomorrow I shall order new LCD, and I shall try.
Something inside me speaks: that LCD is dead  |

mr. Luciano!
I have removed 2 lines in my code:
| Code: |
'Config Lcdmode = Bus
'Config Lcdbus = 4
|
and then all has started.
Many thanks for the help!

Via fuse bytes you can program a delay after reset or power-up.
The delay can be 0 ms, 4.1 ms or 65 ms. Try with 65 ms.
With this delay you will make sure that the power supply voltage
has reached 5V and that the LCD controller chip present on the LCD
module is ready to receive the data from the AVR.
If that doesn't help, then use the Bascom command INITLCD.
Best regards,
Luciano |

Mr.Lachano!
I liked yours idea be relative "LUC_lcd4busy.lib" 
May be, you can write new library for buttons?
The requirement: used any pin any quantity of buttons in the keyboard ((an example: for me 6 buttons necessary only => 2 rows and 3 lines or 3 rows and 2 lines)
The rest pins are not necessary
With the best regards,
Aleksandr. |
