I you wanna make a PWM controller with c-c1, only what you need is: There exist standard 0...230 print controllers with 0 to 10 Vdc input. Only what you have to do is : Use 1 of the DA signal and connect a comperator (connect it on the + input of the comperator ans the - to ground )on it. At the output of the comperator, connect a capacitor 100uF (parallel) and a resistor 4,7kohm (serie). So that's the hardware. simple !! Oké I know that you also can made the last 230V trap, but this is simple. If you wanna make every thing at your own, use a solit-state relay and a capacitor 0,22uF (230 paralell) and a coil about 10..20 mH (230 in serie). Software: define da[1] up port[1] down port[2] count #loop if up = on then count = count + 1 if down = on then count = count - 1 if count > 254 then count = 255 if count < 1 then count = 0 goto loop end This is a very simple programme, but with a extra relay to can turn the motor. succes !!! aufwiedersehen.... |
