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)

Something other about hostmot2

In this code:
IOPortTag & x"00" & StepGenTag & x"81", -- I/O 24
IOPortTag & x"00" & StepGenTag & x"82", -- I/O 25
IOPortTag & x"00" & StepGenTag & x"83", -- I/O 26
IOPortTag & x"00" & StepGenTag & x"84", -- I/O 27
IOPortTag & x"00" & StepGenTag & x"85", -- I/O 28
IOPortTag & x"00" & StepGenTag & x"86", -- I/O 29

What are X"83" X"84" X"85" and X"86" pins ?

Also in this code:
IOPortTag & x"00" & SSerialTag & SSerialRX0Pin, -- I/O 48
IOPortTag & x"00" & SSerialTag & SSerialRX1Pin, -- I/O 49
IOPortTag & x"00" & SSerialTag & SSerialTX0Pin, -- I/O 52
IOPortTag & x"00" & SSerialTag & SSerialTXEn0Pin, -- I/O 53
IOPortTag & x"00" & SSerialTag & SSerialTX1Pin, -- I/O 54
IOPortTag & x"00" & SSerialTag & SSerialTXEn1Pin, -- I/O 55

What are SSerialRX0Pin SSerialRX1P SSerialTX0Pin SSerialTX1Pin SSerialTXEn1Pin
pins ?

any pin with SSerialTag is a Smart Serial interface pin
(for Smart serial peripherals like 7I83, 7I84s etc)

Stepgen pins:

0x81 is Step/Table0
0x82 is Dir/Table1
0x83 is Table2
0x84 is Table3
0x85 is Table4
0x86 is Table5

Table pins from table2 to table5 are only enabled when
table mode is enabled for a stepgen (so revert to GPIO)

Table

Yes i know that is smart serial interface
but why there are rx0 rx1 tx0 tx1 is because of 2 smart serial connections 0 & 1 ?
also what txen does ?
This module has only rx tx inputs not txen www.aliexpress.com/item/1005004250435673.html

For stepgen tag if i want only step dir and enable what pins must define ?
0x81 0x82 0x83 ?

Yes, each sserial pin has a channel number (the are 8 channels per sserial module)
TXen is for RS-485 interfaces (not needed for sserial but required if the interface hardware
needs it)

0x81 is step
0x82 is dir
