Hello everyone !
Since I bought a lot of 12F675, I think to try another schematic : lighting LED using software PWM. I wrote this code ; when power on the PIC, the LED give 20 % of light ; if buton is pressed, the LED lights 40%, then 60%, then 80% and, finally, 100 %. In my dreams :( ...because in practice that don't work like I wish. I know that code is not good...so, please, help me with some suggestion. Thanks in advance.
The variable used in the CASE is specified in the SELECT statement.
The CASE itself only needs the value to compare ...Code:select case counter
case 1
brightness=50
pwm led,brightness,cycle
case 2
brightness=100
pwm led,brightness,cycle
... etc.
Thank You Mr. D ! It's no e-beer on www enough for You as a gift !
Yes, indeed, I am wrong with sintax...but still don't work proper.
Maybe because of my poor english...
So :
-power on, LED lighting 20% (till power off or push button)
-push button, LED lighting 40 % (same as previous)
-push button, LED lighting 60% (same as previous)
-push button, LED lighting 80% (same as previous)
-push button, LED lighting 100% (same as previous)
-push button, LED off till power on again or push button.
It is possible ?
Don't worry about your English.
It's the BASIC Language that's subject... :eek:
Let's see ... power-on 20%, push a button 40% .. etc.. etc... off after 100%
Code:brightness = 51
Main:
WHILE buton
pwm led,brightness,cycle
WEND
if brightness != 255
brightness = brightness + 51
else
brightness = 0
endif
WHILE !buton
pwm led,brightness,cycle
WEND
GOTO Main
Mr.Darrel, You are my guardian angel from far and away !!!
Works verry good. Thank You from the bottom of my heart !
P.S. : " if brightness != 255 then".
You're welcome fratello,
Oops, that's what I get for not compiling it. :oQuote:
