Is there a more cost effective way to do this ? This chip costs too much.

Is there a way to connect two 4x4 keypads at the same port and scan each at a time (with one more switching bit from another port) ?

I have purchased the EASYPIC2 board 20 days ago and I am very disappointed because I had not a clue about the upcoming EASYPIC3. Is it possible to upgrade now ??? Or I have to buy it again ?

Thanks very much dear LGR and zristic. Worked ok on PORTC and PORTD.

Sorry if I was absolute before, but I had tried as much as I possibly could.

Hello ! I need to expand the 4x4 keypad library to support larger keypad matrices, such as 5x5 or 6x6 etc, because 16 buttons are too few for my application. I know that this can be implemented by expanding the keypad interface along two different PIC ports. Is there any library source available in ...

The GLCD_Init doesn't have to be corrected as a command, the issue is that IT DOES NOT WORK with other port configuration and bit sequence apart from which you have commented in your previous post. For example, it does not work with PORTC as control port or with a different bit sequence, like for in...

And this is a much improved version : btw I am trying to find some information on how to change GLCD fonts but there is nothing in the manual or the mikroPascal installatiion !!! program GLCD; var x,ch, Pos,Lin : byte; begin GLCD_Init(PORTB,3,2,4,5,7,6,PORTD); // CS1, CS2, RS, RW, RST, EN Keypad_Ini...

This one works ok with the 4x3 keypad and GLCD. The wierd think is that x = $FF when no key is pressed. The library or the manual should be corrected. program GLCD; var x,ch : byte; begin GLCD_Init(PORTB,3,2,4,5,7,6,PORTD); // CS1, CS2, RS, RW, RST, EN Keypad_Init(PORTC); GLCD_Fill(0); while true do...

I have the small 4x3 keypad, connected it to PortC and run the default example from the mikroelektronica site. The LCD displays the '/' character (#47) all the time and counts like crazy. When I press the buttons, I momentarily read for 1 -> 1 2 -> 2 3 -> 3 4 -> 5 5 -> 6 6 -> 7 7 -> 9 8 -> * 9 -> 0 ...

You should get a parallel one.

You have to use portB for control and portD for data bus, with the default bit sequence.

Well, it is final. The GLCD works only with the following default parameters :

GLCD_Init(PORTB, 2, 3, 4, 5, 7, 6, PORTD);

Nothing else, neither PORTC nor other bit sequence.

This should be corrected in the upcoming microPascal versions.

Have you tried with Glcd_Init(PORTB, 2, 3, 4, 5, 7, 6, PORTD)? Do leds blink on when the program is running? Thank you zristic and all others, especially CharlieM zristic was absolutely right. By using his SPECIFIC configuration, the GLCD worked ok. Here are my findings : 1) It works ok only with t...

Sorry, typing error

I meand RDx -> Dx

Thanks everybody for helping me. It seems that the PIC16 family does not work with GLCD after all, so I am switching to 18F452. For the time being I have the 18LF452 and I will give it a try, check again all the connections etc. The EASYPIC2 has a 8MHz crystal, should I keep it ? I am correctly decl...

Actually I have a 18LF452. Will LF be a problem or it is the same to F ?

Is there a need to change anything on EASYPIC2 (switches, jumpers) in order to connect the GLCD to the external ports C and D (the 10pin plug) ? I cannot get it to work even if I put a 18F452 controller
