My more experienced friends. I am with some doubt and it would like you to help me. 1 - which the difference between Vref+ and Vref - 2 - which operator I should use to extract only the whole part of a division, despising the decimal part. 3 - in a routine IF... THEN I cannot use AND or OR. Example:...

Hi,

There is some chance of doing with MP, a good PIC and a good EEPRON, a Datebase a and even a table where in a column there will be an index and in another column the corresponding value ?

I was using MP 3.0.0.2. Already dowload of the 3.004, and I got to compile.
Thank you

I am using 877 !!!!

I am receiving message " Linker error __RS Bad Bit Number " when I try to compile the routine example of LCD8. program Lcd8_default_test; var text: array[20] of char; begin TRISB := 0; // PORTB is output TRISC := 0; // PORTC is output Lcd8_Init(PORTB, PORTC); // Initialize LCD at PORTB and PORTC Lcd...

I am still with problem in using LCD 16x1 with Pascal routines.
Which modifications in Hardware and Software that I have to do to use LCD 16x2 and LCD 16 x1?

Thanks

Yes LCD is compatible with 44780. I proved that making him to work with other programmed PIC with program written specifically for 16x1 and it worked a lot well. I don't just get to put in operation with programmed routine in Pascal. Is there any command for me to send to LCD and to be recognized as...

I am recovering old scientific apparel that it uses LCD 16x1 and I don't know as programming to use same LCD 16x1. The mikropascal only accepts LCD 16x2. How can I program for use of LCD 16x1?

Thanks

My friend LGR,

I need to do my project inside of my conditions. I need a very small circuit, because I don't have space for you put it. Like this I have the option of using 7 seg. very small. If you know where I can find LCD with dimensions of 7mm x 14mm, I am very grateful.

Tks

It excuses me for that mistake. I discovered that the command LCD_init already configures LCD for their controls.

Now I am wanting to use that routine to read the frequency in 2 or 4 digits of 7 seg. Is that possible?

I thank the information that I received, however I have problems in the connections of LCD for the examples counter8 and freqonlcd, in the connections of the controls RS, E and R/W. In any place I verified those information. Please report where I should tie those pins of LCD.
Tks

I am making project to read frequency using PIC and I am with difficulty in doing the routine in Pascal for that. I am trying monitor in the ascent of the pulse in a PIN and later a new ascent of the pulse. In this interval I count a clock with 1 second. Then I have the period in the wave way that I...
