| Tektronics 1502 TDR vs. 1503 |

| _Wim_:
And the actual software package should it be of interest to anyone |
| _Wim_:
This is the Tektronix software that came originally together with an SP232 module. |

--- Quote from: _Wim_ on November 30, 2022, 09:39:41 pm ---There exists an SP232 module that fits into the 1502B/C unit (they are quite rare on Ebay however). This allows the computer to serially communicate with the 1502B/C. There are of course plenty of serial to USB converters available. Attached is the schematic, firmware image and user manual of the SP232 card. So it should be possible to build your own and write a computer interface software to display and control the 1502B/C. I once planned to do so, but got sidetracked with other projects. --- End quote --- Oh this is great information! In particular the SP232 manual. I think it gives enough information to set the communication. Thank you so so much. I will work on this and see what i get. |

I tried with an ESP32 and a STM32 blackpil, both were too slow to work reliable. Attached the Arduino code I had written for this, but after I realized I really needed the 82C55 to make it work, I lost interest in the project. |

I was definitely considering to use an Arduino to interface with the unit. I've been reading the SP232 module user manual to understand how it works but it didn't occur to me that the arduino wasn't going to be fast enough. This might be more complicated that I thought. Thanks for sharing the arduino code. I will review it later. Maybe it's a case for a Raspberry Pi... need to look into this. Might be an interesting project. |
