Mesa 7i96 with paralel BOB was created by ikkuh

Hi,

I use an 7i96 with a Chinese paralel BOB on connector 3. I use some special firmware so that I can use the BOB for a pwm signal for my spindle. This all works great.

Lately I added a lot of switches through a Chinese USB Arcade controller. That controller takes care of all the inputs and using some of Ask Jerry's video I got it all working.
But now I try to use the not used in and outputs of the BOB, but I just can not seem to make it work. The inputs show up in a halcmd show pins, but I just can not make an output working. How do I control one of the outputs on the BOB in my hal file?

My guess is that

29 bit IN TRUE hm2_7i96.0.gpio.030.out

is the first output on the BOB. But I might be wrong.
Is there anybody who could me out? I am not a wizard myself, and sure could use some help with this.

IO 34 is the first on the header as can be seen from the 7i96 manual:

As I said I am no wizard and need help.
What do I need to do to get the P2 pin (see image) high so I can attach an Led or other load to it? Most Led's will be signaling a gmoccapy/halui state. So the outputs on screen need to be coupled to the Led's controlled by the Bob gpio pins.
According to the 7i96 they indeed start at gpio.034. (Why does the range of output pins start at 030, where are the 4 missing outputs?)

If you could please make a simple example for the mist control maybe? So when I connect the Mist-on in postgui.hal to a button on the joystick card I would like to be able to see the state change through a Led in the button controlled by the Bob.

net Mist-on <= halui.mist.on <= input.0.btn-pinkie

(My git repo can be found at: git.cnckloon.nl/CNCZone/mesa_2019 )

This works and the pictogram on screen changes. Now I need to figure out how to connect the internal state of the Mist component to an output so I can light up an Led.

Pin2 should be IO36

@PCW Can you please help me out, you have been very helpful in the past with the 7i96 card.

setp hm2_7i96.0.gpio.036.is_output true
net Mist-on <= halui.mist.on <= input.0.btn-pinkie => hm2_7i96.0.gpio.036.out # DB25 pin 2

Note that neither statement will work unless you disable the stepgen on DB25 pin 2
by setting num_stepgens=5 in your hal or ini file (since DB25 pin 2 is the sixth stepgen)

Nope, I do not get it to work.

I mentioned I use the special firmware for the 7i96 where the pwm signals are available on the PWM pins, maybe that's the problem?
When I start LinuxCNC

LINUXCNC - 2.9.0-pre0-3195-g57f06b625

then the pin functions do not look right to me (but I am no expert at all).

I did change the num_stepgens:

loadrt [HOSTMOT2](DRIVER) board_ip=[HOSTMOT2](IPADDRESS) config="num_encoders=[HOSTMOT2](ENCODERS)num_stepgens=5"sserial_port_0=[HOSTMOT2](SSERIAL_PORT)
setp hm2_[HOSTMOT2](BOARD).0.watchdog.timeout_ns 25000000

The Enable, B-Axis pins on the BOB are all high.
The X axis,Y axis, Z axis and A axis pins on the BOB are all low.

What does

mesaflash --device 7i96 --addr 10.10.10.10 --readhmid

report

Edit looking at LinuxCNCs startup, I think something is wrong on the driver command
line, maybe quote or space related, since all stepgens seem to have been enabled.
Having all stepgens enabled means the the num_stepgens=5 was not parsed
correctly so there is a syntax error on the command line.

I will be in the workshop in a few hours, will post the report.

I noticed that too, but when leaving out the spaces surrounding the num_stepgens LinuxCNC would not start. I will look into that when I am in the workshop. Thanks for noticing that, it looked odd to me too.
