Is it possible: dimming incandescent lamp with SSR with zero-crossing switching mode

Hi!

I have read different opinions on that but is it even possible to use MCXE240D5 to dim incandescent lamp using microprocessor?

AC line is 230VAC, uC will take care of PWM and syncronizing with AC phase (sinewave) will not be a problem, SSR must be MCXE240D5 and no disturbing flickering is allowed. Of course voltage-driver(ULN2803A) between uC and SSR is used

Some say that it will be ok, some say that only "random fire" will work.

I need to find solution using those specific SSRs.

Is it only possible via good code inside the uC or I should stop dreaming about it?

Thanks to all for answering,

MCXE240D5 is zero-crossing version, not designed to dimming. It will switch on load after voltage crosses zero independent on when conrol voltage is set. You need MCXE240D5R version.
