mesa 7i33 7i37

OUTPUT_SCALE affects almost all PID settings (except offset)

with P=1 / FF1=0.12 was a very good starting point responds very well..
Next is halscope tuning..
Thank you again

This Pin file is correct for 7i80hd+7i33+7i37+7i84 ?

Also how can i use the I/O pins of 7i84 from hal file like 7i37 ?
Is there an example for 7i84 & hal ?

Depends on the sserial daughtercard
7i80hd_16_svss8_8.bit or 7i80hd_25_svss8_8.bit
would be correct for a 7I44 daughter card

You can take a look at a pncconf created configuration
to determine 7I84 connections, or just get the 7I84 running
and:

halcmd show all | grep 7i84

I will use this rs422 module www.aliexpress.com/item/4000345846502.html
to connect 7i80hd with 7i84.
7i80hd P3 -> rs422 module -> 7i84
I don't have now the 7i80hd (is on machine) and pncconf doesn't t give me option to choose 7i44 daughtercard.

7i80hd_16_svss8_8.bit or 7i80hd_25_svss8_8.bit should still work for that

 To create an example hal file with pncconf, you can chose any firmware
with sserial and add a 7I84 (since its just for an example)

Also the

halcmd show all | grep 7i84

Should work on you existing system as long as you have sserial firmware
and it's wired correctly (and the 7I84 is powered)
