Yes, it creates HAL pins. SSerial card tels LINUXCNC which data will be send/receive and LCNC create pins.
You can define read/write, size for each type in bits (8 bits are 256 steps) and min max value (IEEE-754). maximal 96 bits in and 96 out.
for type encoder are creates some parameters like scale automaticaly.....
you can add special parameters yourself, this value is not transfered in data packet but by address when changed (now I canot remember how).

That looks very interesting.
Does it create pins in HAL like a real sserial node?

Yes I can,
Tomorrow on work. I can make simpliest example. send 1 bit to sserial card stm32f103c8 bluepill and turn on/off led and 1 bit back with led status.
Now I am working on versatile template, where will be possible to do select types from predefined lines and program makes everything itself. calculete PTOC, create variables etc. Of course except for HW pin operation.

I started on that and needed to modify the code for strm32 - I didn't get it to work yet as I ran out of time for it.
Do you have code edits you could share?

In LinuxCNC Master the limit is now 224 bits if you use the sserialB GTAG (198)
github.com/LinuxCNC/linuxcnc/blob/master...mot2/hostmot2.h#L133
It was my intention to support the use of minifloats in addition to (part of) IEEE-754
github.com/LinuxCNC/linuxcnc/blob/master...mot2/sserial.c#L1531
ie 8, 16, 32 and 64 bit floats.
Though looking at the code it doesn't seem that 8 and 16 bits are implemented yet.

Hi,Here is very simple example
I change cca 10 lines in fdarling template
there is
1 bit from LCNC to stm32f103c8 turn on/off pc13 buildin led
1 bit from stm32f103c8 to LCNC copy input to output
I use int_8 for 1bit because opposit side automatically align size to whole byte.
Sorry my arduino ide is automaticaly set to czech language. but perhaps the picture shows how to set it up.

This is excellent! Thank you.
As soon as I get back from work rotation I'll try it out and let you know!

Hi Andy,
this is great news. I thing 96bits is not enought.
I spent a few nights reading (and writing) the code and I have a question.
When I try to write 4 bytes (32bits) to non volatile variable, linuxcnc only send 2 bytes. how can i send 4bytes information to my own sserial card? I want to add my own non volatile variables and control it.
Thanks Martin
Read is no problem. LCNC ask for forexample nvunitnumber with 4bytes and gets 4bytes. But, writing is different

What datatype? is datalength correct?
The code looks like it should work:
Seems to match
"REFERENCE INFORMATION
SSLBP
REMOTE WRITE EXAMPLE:
For a remote word write, the sequence of operations is as follows:
1. Issue a STOPALL (0x800) command, wait for COMMAND register clear to verify stop command completion.
2. Issue a setup START command (0xFNN) with bitmask (NN) of channels to start
3. Wait for COMMAND register clear to verify start command completion. (may be many mS)
4. Read data register to verify that all selected channels started (a 1 bit means a fault in the channel that the bit represents)
5. Write the new parameter data to the selected channels Interface0 register (right justified)
6. Write LBP word write command (0x65) in the MSByte ORed with the parameter address to the selected channels CS register. (0x6500PPPP)
7. Issue a DOIT Command
8. Wait for the command register to be clear
9. Check that the data register is clear, any set bits indicate an error . Repeat from step 5 for any additional remote parameter writes
Remote write byte, word, long and double are basically equivalent, the only difference being the LBP command (0x64,0x65,0x66,0x67 respectively) and the size of the data written to the interface register(s)"
The interface registers are 32 bits, so the data should fit.

Hi Andy,
thanks for reply.
Now it is ok. in case I use sserial not setsserial
I had old LCNC 2.7.15, now it runs on 2.9.0 pre0 (17.3.2021 update to master branch)
I use 7i92 firmware 2x7i76 with one 7i76
here is my definition
LBP_PDD_RECORD_TYPE_NORMAL,.DataSize = 32,.DataType = LBP_PDD_DATA_TYPE_NONVOL_UNSIGNED,.DataDirection = LBP_PDD_DIRECTION_OUTPUT, .ParamMin = 0x0,.ParamMax = 0x0,.ParamAddress = PARAM_BASE_ADDRESS+16,"None\0NVNumber\0"}}
and lcnc create param
u32 RW hm2_7i92.0.cust.0.0.nvnumber
1. I tried to write param to card throught setsserial
halrun
loadrt hostmot
loadrt hm2_eth board_ip="192.168.1.121"
show param hm2_7i92.0.cust.0.0.nv......
loadrt setsserial cmd="set hm2_7i92.0.cust.0.0.nvunitnumber 0x12345678"
comunication is.
0xEC 0x01
0x00
0x65 addr addr 0x43 0x21 crc this is only 16bit
......
......
2. I tried set nvnumber in custom_postgui.hal
it is too late because comunication is already in progress
3. set param in cutom.hal
setp hm2_7i92.0.cust.0.0.nvunitnumber 0x87654321
lcnc say....A non-volatile smart-serial parameter has been changed
parameter is set now to 0x87654321. (only when it is different from read value)
comunication
0xEC 0x01
0x00
0x66 addr addr 0x21 0x43 0x65 0x87 crc this is 32bit.
thanks
I have ones more question,
I have second mesa card 7i76e
I made new firmware with another sserial on p1 (p2)
comunication is fine, lcnc start and can see all pin and param from my custom card.
but i cant get information from
mesaflash --device 7i76e --sserial --verbose.
there is no cookie send to card.
I tried original firmware 7i76e with 2x7i76 and situation is same.
there are
TXdata0 and RXdata0 on internal pin 7 8 onboard sserial
TXdata1 and RXdata1 on internal pin 9 10 mesaflash read ok
TXdata2 and RXdata2 on P1 pin 7 8 mesaflash dont comunicate
TXdata3 and RXdata3 on p1 pin 9 10 I didn't try
TXdata4 and RXdata4 on p2 pin 7 8 I didn't try
TXdata5 and RXdata5 on p2 pin 9 10 I didn't try
whats wrong?

I know very little about Mesaflash. I suggest asking that question in the Driver Boards part of the forum where someone who does know Mesaflash migh see it.
