I can do that, but if it has already been done, why recreate the wheel.
i suppose but most, if not all only have the 3 pins for the encoder / switches
Nevermind, I'll do it myself.
Just wondering if anyone checked this out. anyone see any errors?
The project is working fine here!!!! I will post some pictures later.
Just three doubts:
- Can I control 16x2 LCDs?
- How activate the buzzer using LCDSmartie?
- Can I control the contrast by software?
can anyone check my circuit for any errors please?
If the schematic is right there is no reason
why it should not work. There is a wire link
that you can replace with a track
yes i know for that wirelink but is made for quick off backlight
Im not 100% sure that the PCB is O.K.
Your circuit is ok!
And a information: the circuito is plug and play with 16x2 and 20x2 LCD!
I test today!
is plug and play also for 4x20
i can not get a bc184L trans. can i use another bc trans. instead ? if yes ... bc in general or a special one ?
edit: maybe the 547 is right ?
i will be using BC548B
My LCD working!
I am having problems with the encoder. I receive any key when I pressed the buttons. I test with Hyper Terminal too and anything.
Anyone can help?
you have not soldered the legs of the chip associated with the encoder
Sorry for this...
I sold just the pins to test USB and LCD. And forget to solder others.
Thank you and sorry!!
Well today I soldered my USB LCD controller according to Waneeboy diagram (see below) I have just one problem there is no way to turn backlight on. Do you have anny suggestions? Transistor maybe ?
I just resoldered transistor - just turned it around for 180 degrees - I have backlight on now but I can't turn it off with Lcd Smartie ( I was able to do it when LCD was hooked to LCD port)
The link is down, Could someone please be kind enough to re-upload the compiled code for my 18f4550?
