Builds a modern, testable API for the Prologix GPIB-ETHERNET controller (GPIB-USB structurally supported but untested, no hardware available): Transport abstraction (Ethernet now, serial later), GpibController for the full "++" command set, a clean-room netfinder discovery client that fixes a real chr()/struct-format bug present in vendortools/nfutil.py, and a CLI (discover/config/info/terminal). vendortools/, pty-gpib-emulator/, sampledata.txt and the manual PDF are kept untouched as reference material. Depends on the sibling bits package (editable, not yet pinned -- see its own commit) for MAC formatting and IEEE-488.2 status-byte bit access. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# progpib
|
|
|
|
A modern Python 3 API for the [Prologix](https://prologix.biz/) GPIB-ETHERNET
|
|
controller. GPIB-USB is supported behind the same interface but is
|
|
**untested** -- no GPIB-USB hardware was available while building this
|
|
package (see `progpib/transport/serial.py`).
|
|
|
|
## Install (development)
|
|
|
|
This package depends on [`bits`](https://git.groesz.org/Groesz.org/bits)
|
|
(distribution name `binary-bits`), currently used as a local editable
|
|
checkout rather than a pinned PyPI release -- install it first:
|
|
|
|
```sh
|
|
python -m venv .venv
|
|
.venv/bin/pip install -e ../bits
|
|
.venv/bin/pip install -e .[dev]
|
|
```
|
|
|
|
## Usage
|
|
|
|
```python
|
|
from progpib import discover, GpibController
|
|
|
|
# Find controllers on the LAN (broadcasts on every local interface):
|
|
for device in discover():
|
|
print(device.mac_str, device.ip_address, device.name)
|
|
|
|
# Talk to one:
|
|
with GpibController.ethernet("192.168.1.50") as gpib:
|
|
print(gpib.ver())
|
|
gpib.addr = 5 # address the instrument at GPIB primary address 5
|
|
gpib.eos = 3 # no GPIB terminator appended
|
|
gpib.eoi = 1
|
|
response = gpib.query("*IDN?")
|
|
print(response.decode())
|
|
```
|
|
|
|
## CLI
|
|
|
|
```sh
|
|
progpib discover # find controllers on the LAN
|
|
progpib info <ip> # controller version/mode/config
|
|
progpib config --mac AA:BB:CC:DD:EE:FF --dhcp
|
|
progpib config --mac AA:BB:CC:DD:EE:FF --static 192.168.1.50 255.255.255.0 192.168.1.1
|
|
progpib terminal <ip> --addr 5 # interactive pass-through terminal
|
|
```
|
|
|
|
## Reference material
|
|
|
|
`vendortools/`, `pty-gpib-emulator/`, `sampledata.txt` and
|
|
`PrologixGpibEthernetManual.pdf` are kept as historical/reference material
|
|
(original vendor tooling, a separate PTY-based emulator side project, and a
|
|
captured protocol session) -- nothing in `progpib/` imports from them.
