datapainter

Hello.
What is the status of mesa datapainter firmware - linuxcnc integration ?
Thanks

Firmware is working , still undecided on how to integrate FIFO devices into hal
(where does the data come from and how is it passed via hal to the driver)

Any newer status?
What can i see for this sampler hal_sampler ?

From manual seems that streamer halstreamer is nearest existing option.

streamer(9) and halstreamer are used together to stream data from a file into the HAL in real time. streamer is a realtime HAL component that exports HAL pins and creates a FIFO in shared memory. hal_streamer is a user space program that copies data from stdin into the FIFO, so that streamer can write it to the HAL pins.

What can i do? modify hal_streamer to read not from stdin but from bitmap-image-cam file
and copy data to FIFO?
How then streamer will get these FIFO data and synchronize motion with laser fire pulses?

I have XY2/analog galvo laser and gantry style laser but they have high linear speed( > 2m/s) so base thread is not an option only servo thread with mesa card+datapainter firmware.
Co2 laser source to fire has typically pwm input
0-20khz with power control via duty cycle control.
dpss lasers have more complex driving because they are pulsing lasers not cw that need driving rf power supply of acousto optic modulator inside cavity.This is for laser pulse time control typicaly in the range 3-10 ns.

can you describe with more details what must be done ?
