A simple Java graphical user interface for Girino, a Fast Arduino Oscilloscope.

girinoscope's Issues

MHz?

Thanks for sharing this!

Now this is only cosmetic of course, but… the acquisition rates should be kHz I guess and not MHz. Pity.

No Girino detected on <appropriate device path>

I have installed Girino on an Arduino UNO and it still appears to not detect it? I've done the necessary code changes and I can't get any readings.

New logo for Girinoscope

I wanted to contribute to Girinoscope. I designed a logo for Girinoscope. If you like it, I'll send you the files.

Hangs after a while

In "loop" acquisition mode, after a few minutes (sometimes after a few seconds), no more data is acquired. Either the Girino didn’t get the message that it is supposed to acquire data, or Girinoscope isn’t happy with the response it got. Hard to tell which.

Clicking the stop button, and then restarting works.

Does this only happen for me?

stm32duino port

hi i'm thinking about adding a port for the girino arduino firmware to stm32duino
http://wiki.stm32duino.com/index.php?title=Main_Page
https://github.com/rogerclarkmelbourne/Arduino_STM32
the intended board is maple mini or blue pill
https://www.leaflabs.com/maple
the boards are rather low costs
https://www.ebay.com/sch/i.html?_from=R40&_nkw=stm32f103c8t6&_sacat=0
the mcu is STM32F103C8 Arm Cortex M3
https://www.st.com/en/microcontrollers-microprocessors/stm32f103cb.html
72mhz arm cortex m3, 20k sram, 64k or 128k flash
2 x 12-bit, 1 μs A/D converters (up to 16 channels) - in fast dual interleaved mode may reach 2 million samples per sec
would you be willing to handle pull requests for the java code?
the main things are:

• the base frequencies are 72mhz rather than 16mhz, the prescalers would be different (at least the base frequency is different) higher sampling rates
• i may want to support the 12 bits adc (i think currently 8 bits are used)
• that would mean bigger buffers possibly 16 bits x number of samples large, and Girino would need to handle different word sizes
  but i figure that some changes (possibly rather significant) may be needed on the java frontend
  e.g. that we may need to abstract further and build girino 'factories' and need to use more parameters
  e.g. base_frequency, frame_size, word_size, adc_bits, chip or device
  so that if the additional info is not present, fall back to the standard girino settings
  at the moment i'm still prototyping and trying things out so nothing concrete as of now.
