USB scopes

There seems to be Linux USB scopes around – would it be possible to use one with RO? |

I have a Picoscope, with which I am very pleased, and which has a very good Linux app – I run it under Ubuntu. Unfortunately Pico Technology don’t seem to want to release source or API. |

Picoscope a UK company? |

Yes. |

I am owning a (Meilhaus RedLab) 1608FS-Plus DAC. Such devices are going into a similar direction. I didn’t found time until now to write an according driver for RISC OS but there had been according driver codes in C and based on them I made two small tests in BASIC which worked. Meilhaus was not the real manufacturer but imported the device. The whole range is a problem. I searched really long until I found this DAC. The most devices in this area are not having open code or API descriptions any longer. This may be due to technical tricks in the electronic which are compensated by some software tricks. Formerly this was intergrated in the device itself but these devices are unfortunately long gone. |

Sounds like ‘Thomas’ uses AI – according = supporting? :-) |

I’d say he’s doing pretty well in a second language. |

While it’s not used much these days, “according” can also mean “corresponding” so the word isn’t necessarily wrong. Plus, it’s clearly not AI as the message actually makes sense. It’s just somebody who had the decency to contribute in our language. Kindly don’t mock. |

Merci beaucoup Rick!!! , corrections are appreciated, it’s very easy to make nonsense,an AI does a lot of it…. I don’t have a USB oscilloscope, I use my Steinberg MKII audio interface which allows sampling up to 192K with a sensitivity of 0dB to -60dB. With Colin Granville we adapted Jim Lesurf’s program !USBScope, at his request, to create a desktop version. I have TekScope oscilloscope which has a serial interface, but no program yet to use it with RO.I think I can test the interface and protocol with !Hearsay. |

This was probably kicked off by an article on my blog with some really simple software to turn a data dump from a JYE DSO Shell into something that was rendered on RISC OS. For the record, the DSO Shell is a kit based upon(ab)using the ADC of an STM32 microcontroller to create an oscilloscope that can do maybe 100kHz or so. All in (board, bits, screen, case) it’s like €40 or something. It normally runs autonomous, but if you hook up a 3.3V serial port and press two buttons it’ll dump the current status. It’s not a great scope, but for poking around to discover potential serial ports, and “seeing” what sorts of signals drive the printer of a printing calculator (my two most recent uses), it’s adequate. And I made some software because crappy photos of the screen were…crappy photos of the screen. ;) I’ll need to thicken up the trace lines though in order to not have the mobile-view images look awful. Not quite sure how to do that, though… |
