If using a Mesa card, this also could be done with a FPGA oneshot with a trigger in
and end of timeout pulse output. I'll take a look at adding this.

Just wondering Peter if you have taken a look at this.  More curious than pushing as I was going to get a PCB made, now I'm thinking about just making one myself as there are only a few components if I loose the attiny.

Thanks,

Rob

I started the firmware coding (basically a universal one-shot timer)
but it will take a while as I am pretty busy these days hunting for parts.

I expect to finish towards the end of July

thanks Peter, no problem won't bother you.

I did think there may be a few more people who thought it may be a good idea to integrate such triac control option directly from with linuxcnc.

At long last I finished the oneshot module and driver support.
It probably has some bugs but does seem to work as expected.

It has two 32 bit timers so can do phase control, high resolution
PWM etc.
