It's been working fine now.
I have directly wired LCD to ECIO, wires are about 10cm long.
If I detect where my problem was, I'll tell you.

For unknown reasons, the LCD started working!
...But now I made a little change to printed text in program, and send it to ECIO but it won't work. Strange. Change I made just altered printed text...

And it works again o_O
Dunno why, but I don't care as long as it works.

As I said it works with multiprogrammer w/ 16F88, but not with ECIO. Here's the program for 16F88. The program for ECIO is exactly the same, except for different processor of course. 16f88_lcd_test.fcf And here's how I connected LCD. The picture is kinda big, so I suggest opening it in it's own tab....

Hi. I'm again having trouble with ECIO40p :/ The LCD display is 16x2, model W162B-N3LW I should have right connections etc but it still doesn't work on ECIO. However, I managed to get it work with PIC16F88 on multiprogrammer. Connections are the same, program is the same except for different process...

Ok thanks. I think that I just get 0ohm resistors -> better sure than sorry

Can I use 1ohm jump resistor with I/O ports or any other ports? I don't have 0ohm jump resistors.
Goal is to make clean looking circuit board, plain wire would look stupid in middle of other components.

As I thought. Thanks for the answer

Hello.
Ecio40 has GND in pins 2 and 26. Do I have to connect these, or are the pins already connected inside the chip? Or is it possible that GND in pin2 must be used only with VDD out?

So I have been trying to make the program, and I attached my latest attempt.
How accurate is this? Is it right?

Could someone please help me?
Just please help me out with calculating PWM to voltage and making the stepping.
I found out this formula: Voltage_reference / bits * PWM which is in my case 4 / 255 * PWM_variable, right? This should calculate volts, but how I calculate mV ?

I know how to enable PWM, and adjust it with variables. That's it... I have attempted, but I can't figure out how is the voltage adjusted, and how it should be stepped in precise steps. In attached .fcf file I have enabled PWM and adjusting it with variable. Variable is controlled with buttons A0 an...

Hello. I don't have a personally owned copy of Flowcode 4, so I can't use it's forums. I need to make this kind of program: http://tinypic.com/view.php?pic=1zh1ily&s=5 However, I am a n00b so I thought that someone could make it for me and explain what is happening? Or atleast give step-by-step ...

Hi. I want someone to check my wiring out and tell that if there is something wrong or is it good to go. Also, A/D and PWM are build-in in ECIO 40P, right? Meaning that I don't have to attach any more components to my circuit. LCD has brightness POT, I'm not sure if the buttons are wired correctly b...
