Project 2 – Hello World with Parallel LCD

For project 2, we will show you how to interface the SK40C board will parallel 16x2 LCD display. The connection are simple and the coding are easy to learn. We are going to display the “Hello World” on the LCD display by just adding a library that has been done for you.

    Yeah, I did that. Got a female header from a friend and soldered it to SK40C.
    After doing some troubleshooting, we realized it was actually the LCD display. It might be faulty or I soldered it wrong but the second backup LCD which I also soldered myself work perfectly.

    Guess it’s all fine now, I might try re-soldering the male pin header on the faulty LCD to see if that’s the problem.

  2. You will need wireless device to transmit the data from the weighing machine to another room. It will become more complex, but it is possible. Do continue the discussion in our technical forum, thanks .

  3. Hello,

    Just started on this PIC16F887 + SK40C projects and I wondering if I’m doing this correctly. The male header connector provided with SK40C is meant for a separate LCD display right. So I soldered the connector to the LCD display (just like the image in LCD BACKLIGHT CONTROL section above) and just plug it to the LCD slot on SK40C (no soldering here).

    I noticed that some of the connection are broken like for example the R/W of the LCD is not connected to GND and some other pins as well (Checked this with multimeter continuity test).

    I think my solder work is okay but it’s just that I think some of the header pins are not directly touching copper thing (since it’s loose). How do I fix this? I tried wiggling it around a bit to find the perfect position but nope doesn’t work.


  4. Hi, I have a small question.

    Is it possible to replicate the reading from an electronic ditigal weighing scale to another screen in another room.I am trying to avoid a lot of wiring. Is it possible to do this? hope someone can answer me this. If this is possible can you also advise me the diagram for this. I am not a tech guy but would love to do this myself if I can get the right information.

    Glad I found your website. I really like the things you people are doing.


  5. This is due to different version of HI-TECH Compiler. You can try searching the solution in our technical forum as there are people discussing about it before.

    when i build lcd programme i get this error..please help me out

  7. Have you connect the jumper pin on SK40C? SK40C come with a jumper pad for user to decide whether to activate the LCD backlight or otherwise. Anyway do discuss in our technical forum where you can show photo of the whole project setup and we will try to trace the possible root cause.

  8. hi, Im new here and just bought sk40c + pic18f887a and I attach a blue LCD on the board.
    When testing at shop the LCD had words and blue backlight. but after I attach it on board and power on it at home, the LCD does not had back light. does my LCD back light spoilt? I understand the [] [] [] [] [] display on LCD because I don’t program anything in the board yet, but I don’t understand why there is no LCD backlight. please help thanks
