Hello.
I'm continiuing to evaluate PBP pro, so I built a simple circuit with 16F682A, two leds and a button (tied to Vdd via 10k resistor and when pushed, connects the pin to gnd) leds are tied to rb0 and rb1 via 1k resistors.
The code is below:
The code works almost as it should do, but with a nice twist. When launched, if I press the button for the short period, the 2nd lend comes on and 1st one continues to blink, as it should do. However, if I press the button for a bit longer time, or press it 2nd time, the 1st led stops flashing!Code:LED VAR PORTB.0 LED2 VAR PORTB.1 brep var byte mainloop: BUTTON PORTB.3,0,255,10,brep,1,secondled High LED Pause 250 Low LED Pause 250 Goto mainloop secondled: high LED2 return End
What is the reason?
Also, I don't like that button should be handled in the loop with all my delays. Say I have somewhere in the code statement: pause 2000. This means, that even if I press button, I have to wait 2 seconds for software to react for it? is there a workaround for that? For example, on ZX Spectrum, if any key was pressed, the pause command, regardless of it's parameters, was terminated and next step executed immediatelly. Is same feature available here?
