I atached photo of my wrong LCD. I do not know, what is the problem with LCD.:confused:
Display is marked as MC10621E8-SYL, *W 4034
But after changing, everything is OK.
To clarify... the reason I asked the above question(s) is because it seems to me that if the LCD was displaying any reasonable characters then the LCD was working.
Was it an LCD contrast issue or...
If I may jump in here now that your problem is solved...
So just curious... Was the 'bad' LCD displaying garbage characters or was it displaying a somewhat valid number??
Problem is solved, I changed LCD display, it is OK. :)
Thanks for your help.
Source is pressure sensor (output 0 - 1V), wchich is normaly working with 10-bit A/D - PIC16F877 conection.
I built conection with PIC18F2455, but not working properly. :confused:
What is your ADC source and how is it connected?
What are the current readings and what are the expected readings?
ADCON2 = %10000000
ADCON2 = %10000011
it is still the same :confused:
and set the conversion clock to fosc/2
way out of specs
ADCON2 = %10000011 ' ...and right justify result and use frc
I have written code for 10-bit A/D conversion with PIC18F2455, but not working properly, value on LCD display is not correct.
I used sample code from melbas written for 10-bit A/D conversion...
