A prototype of an external display/monitor/instrument controller for RS232 equipped DMM. C++ code on an AVR uC. Controlled by Processing sketch via USB>Serial-uC. Can trig and do simple remote control of the meter via RS232. Stores high speed continuous sampling to EEPROM. Next: Buy 10 inch TFT display, make menu (buttons, PS2 keyboard in remote location, touch screen). Make advanced real time statistics. Graphics. Enable write to file on PC. Utilize simple GPIB predefined set up from notepad files. |

Now this is a cool idea even if I am not sure how practical it is. :-+ |

Thanks. Yes, many of my ideas are may be too much effort for a one off gadget and may never be realized. But code for a histogram and a "scope" plot is easy to find and modify, and all you need of data is the RS232 stream from the DMM. Imagine this on a 10 inch color TFT LCD (USD 60 on fleabay with free driver code). BTW I already have a "noise-plot" in C++ for Arduino running in Processing on the PC. Not many lines, and directly portable from Processing to the Arduino IDE. |
