How to use multiple buttons in mikroPascal PRO?

[jd2000]

I am a new user of mikroPascal PRO, and I have a question: How to detect multiple buttons connected to P0.0, P0.1, P0.2, etc? Your sample code shows how to use one button only, and I don't know how to define the "Button_Pin" if I use several buttons.

Here is you sample code for one button connected to P0.0:

program Button_Test;
var Button_Pin : sbit at P0_0_bit;
var oldstate : bit;

begin
P0 := 255; // configure PORT0 as input
P2 := 0xAA; // initial PORT2 value
oldstate := 0;

while TRUE do
begin
if (Button(1, 0) <> 0) then // detect logical one
oldstate := 1; // update flag
if (oldstate and Button(1, 1)) then // detect one-to-zero transition
begin
P2 := not P2; // invert PORT2
oldstate := 0; // update flag
end;
end;
end.

Hi!

I have notified our developers about this issue. We'll modify the Button function
so that it has two more parameters (port and pin).

Best regards

OK, thank you. Please let me know when the new program is ready.

Hi. I have seen that you were going to implement new parameters for Button (PORT and time). Is this already implemented? Where can I find this? I am a new user and I realized it is already implemented for MikroPascal PRO for PIC. Are there other new implementations for 8051? My software version is 2.2

Is it already implemented for MikroPascal PRO for 8051? I have been waiting for this since 2010. I am working with version 3.5 now and it was not implemented.

I have a problem. Every time I have to test an INPUT port state I have to write 1 on it, otherwise I cannot read it.
I know I have to configure the port as INPUT writing 1 on it, but I thought I had to do that only once.

Is there any anser for it? Microcontroller is ATMEL 89S8253.

Thanks,

Carlos
