NOTE: This version is OBSOLETE!! Please go tofor the 6.1 release software and documentation. --- Version 1 of this project is aimed to provide a cheap and quick GPIB solution to those that need to gain control over a single instrument and interact with it (e.g. To calibrate instruments that can be calibrated by GPIB only -- 6632A Power Supply being a good example). Windows 10 serial USB problems The latest (January) update to Windows 10 seems to cause problems with the USB serial driver when connecting to an Arduino. I can upload a small sketch to an Arduino Mega, but larger sketches fail with an 'averdude checksum error', and I get periodic freezes when sending commands via USB serial to my 3D printer.

The only feasible solution is to go with a Prologix USB to GPIB converter, still it would have cost me some tens of bucks. Other solutions required buying or building hardware. On the other end I had an Arduino UNO floating around on my bench waiting for a problem to solve other than blinking leds or writing 'hello world' on an LCD. So I decided to face the challenge of writing down a c++ program and have the Arduino play the adapter role I was looking for. To make a long story short. (I supposed that GPIB was simple at least as much RS-232 is,. And it is not! I was wrong again!) after reading a lot of IEEE-488 documentation and giving a try to a similar program I found over the internet, I got a decent implementation of a GPIB controller out of my Arduino UNO. This post is dedicated to describe the project. Because of the hard effort I put on the project, I kindly request you to donate a couple of bucks if you find this program useful for your hobby.

Below you'll find the program documentation describing the implemented functionalities, limitations, commands syntax and hardware required (close to null., just a bunch of wires and a plug). ==== Disclaimer: This program is provided as is. Compal fl90 vista 64 drivers windows 10. It is a hobby work. It doesn't work correctly. It has not been tested. It can damage your Arduino and the device you connect it to. Can have unexpected behaviors, can get stuck at any moment, can read and write data to/from the device in ways you might not expect. It can send wrong or erratic commands to the device. Can display data that differ from the actual data the device sent out. Can address GPIB devices differently from what you might expect. I have not conducted any speed test; the maximum speed supported is simply unknown. Is does not follow any official standard. Only a minimum set of the functions included in IEEE-488 is barely emulated. Hardware limitations: the lack of a GPIB line driver has two major implications: first: your Arduino is directly connected to the device GPIB port without any form of electrical protection of buffering - this can potentially damage your Arduino and/or your device; second: what can happen if you connect more than one GPIB device to the BUS is unpredictable both from an hardware and software point of view. I only experimented with a single GPIB device connected to the BUS. This program is inspired by a similar job done by IW3IIF who started from what he has found at ---- Introduction This program is an attempt to have the Arduino to implement a GPIB controller. The objective was to have a way to get control of test instruments to send and receive commands to/from such devices via GPIB. Future implementation may include binary data transfer mainly aimed to get plot data out of test instruments like oscilloscopes or spectrum analysers. This is version 1.0. As everybody knows nobody should trust version 1 subversion 0 of any program. But that's it. Give it a try. Despite the disclaimer I can say that the objective has been successfully met; with this program uploaded to an Arduino UNO I can now control my hobby lab GPIB instruments and even calibrated some of them. I hope it can work with yours as well. There are a bunch of actual limitations: - the program operates in controller mode only; it is not (yet) able to behave like a device. - two important GPIB pins are not correctly managed: REN and SRQ. - Serial poll is not implemented. - subaddressing is not implemented. - only ASCII transfer have been tested. It shouldn't be too difficult for me to implement binary transfers in version 2. Hardware set up instructions: The hardware needed is simple: just a bunch of wires from the GPIB plug to Arduino pins. Here is the pin mapping: A0 GPIB 1 A1 GPIB 2 A2 GPIB 3 A3 GPIB 4 A4 GPIB 13 A5 GPIB 14 4 GPIB 15 5 GPIB 16 12 GPIB 5 11 GPIB 6 10 GPIB 7 9 GPIB 8 8 GPIB 9 7 GPIB 11 NOTE: GPIB pins 10, 17-24 goto GND, but: • GPIB pin 17 (REN) has to be investigated further.stay ready to reroute it differently in the future; • GPIB pin 10 (SRQ) has to be investigated further.stay ready to reroute it differently in the future; • GPIB pin 12 should be connected to the cable shield (not used here - I left it n/c). Build the the shield the way you want. Nothing is simpler provided you have a minimum electronic construction skills. For testing I preferred the 'flying' shield visible in the pictures but the actual construction is your choice. The male GPIB connector was realized sacrificing a CENTRONICS 32pins male connector out of a PC parallel printer cable.
