tervehdys
olen tÀssÀ tuskaillut ja yrittÀnyt saada valojen himmennyksen toimimaan arduinon sarjaporttia (serial 9600) kÀyttÀen, ja siis useampaa kuin yhtÀ.
olen tehnyt TRIAC-himmentimen nÀiden ohjeiden mukaan:
http://www.instructables.com/id/Arduino-controlled-light-dimmer-The-circuit/
tarkoituksena on kÀyttÀÀ tuon mallin rinnalla saman ohjeen mukaisia himmentimiÀ, pois lukien zero cross osio; teen sen vain yhdesti jota kÀytÀn muissa himmentimissÀ.
saan edellĂ€ mainitun ohjeen mukaisesti yhtĂ€ valoa ohjattua oikein mainiosti, mutta oma Ă€ly ei riitĂ€ muokkaamaan koodia siten ettĂ€ saisin useampaa âkanavaaâ ohjattua.
olen yrittÀnyt penkoa internettiÀ ja vaivannut omaa pÀÀtÀ, mutta tuloksetta.
tÀssÀ on lupaavin koodi mitÀ olen löytÀnyt, mutta siinÀkin arduino valittaa jotain mitÀ en tÀysin ymmÀrrÀ ja se jÀÀ lataamatta error viestin takia.

DIMMERS 120V 60Hz (8-channel Possibly more)

Material part:
- Triac driven by a digital output via an optocoupler
- AC opto-coupler for detecting the zero crossing of phase
Software part:
- A hardware interrupt input 2 at the zero crossing of phase
- A software interrupt that occurs between 100us and 1400us.
=> Interrupt interval is variable to obtain a light curve by linear orders, because of the shape of the sinusoidal signal.
we have:
- Detection of the transition to zero on input 2
- execution of detection_zero (): processing channel with a setpoint of 0% and 100%
- deactivating hardware interrupt, enabling the software interrupt on the basis of delay [0]
- interrupt after delay [c2] ?s (c2 = 0)
- execution of controle_canaux ()
=> Index increment c2
and if c2 is greater than 49, then this is the last cycle
=> Turn OFF of all channels
=> Activate the hardware interrupt
otherwise:
=> Activation of output channels with 98% to record (either a 469?s delay) or if
=> Interrupt reconfiguration of time with another delay, delay [c2]
To change the setpoint of a channel, you must send via the serial monitor a frame of the form:
" D/0/45/F"
=> Space
=> âDâ to indicate the start of the frame
=> â/â As separator
=> The affected channel (0 to 7 here)
=> â/â As separator
=> The desired level (from 0% to 100%)
=> â/â As separator
=> âFâ to indicate the end of the frame
Once the frame received, the function sscanf is responsible for retrieving data.
It converts the received record levels (0 to 50 levels)

tuolla koodilla kaksi kanavaa toimii itsenÀisesti, mutta silti en saa siitÀ tehtyÀ sellaista ettÀ se minun serial monitor kutsuihin vastaisi.
tuo on siis alkuperÀinen koodi, joten siksi siellÀ on serial kommentoituna.
mutta yhteenvetona, olisin suuresti kiitollinen jos joku voisi minua tÀssÀ auttaa.
sÀhköiset kiitokseni jo valmiiksi
