and test code ! :

program MyProject

main:

if 150 > 300 then
portc=255

Run "Portc=255" !!!!!!!

Hi,

You forgot to initialize and configure the port.

Try this code, code works ok:

Code: Select all

program MyProject

' Declarations section 

main:
'   Main program 
 
  DDRC  = 0xFF                                      ' configure PORTC as output
  PORTC = 0xAA                                      ' initial PORTC value you can delete this if you want

if 150 < 300 then
   portc = 0xFF
else
   portc = 0x1A
end if
end.

Best regards,
Peter

Hi , Peter

in avr
When starting to work DDrX = 0 (all ports is Input)
and Portc = 255 ===> All PullUP resistors in Portc active

It does not matter!

A Question :
ex)
if 150 > 300 then
portc=255
else

end if

150 is smaller than 300
"Portc=255" command should not be executed

ex2)

program MyProject

dim c3 as char[3]
dim b as byte
main:
UART1_Init(19200)
b=0
if 150> 300 then
b=1
else

end if
ByteToStr(b,c3)
UART1_Write_Text(c3)
UART1_Write_Text("|")
end.
'---------------------------
150 is smaller than 300
"b=1" command should not be executed
But "B=1" command run!!!
and .... c3=1 !!!!

Please Test Attach File in Proteus software or ...

Hi, Peter

Please see screenshots in attachment and test again.

Hi,

I tested the simple examples that you posted and I didn't manage to reproduce the same behavior in my compiler,
like my colleague Petar already mentioned.

Please, try to update your compiler (Help -> Check for Updates).
Last version of mikroBasic PRO for AVR is v6.0.1.

Best regards,
Marina
