Lower machine, basically have no problem,
Now PC, a began to learn programming, didn't feel what's the problem, but lower after understand the
This PC I don't know what to do,
Mainly how to put the waveform display,
Try to use a serial port to read data, first under a machine was used to simulate a triangle wave data, said know is to send a cycle of data from small to from large to small
But this PC how to receive, I tried it on, wayward, also saw some information, just don't understand, from the rational serial data is 115.2 KHZ
This data quickly, how to display, if later with USB, the speed of 40 m/S, how to display, this also related to many, resolution, sampling rate, the

CodePudding user response:

Upper machine and lower machine communication can be divided into two modes: low sampling rate using real-time transmission, high sampling rate using a machine to collect data cached in memory stop collection, after will cache the data again after the upload, display waveform using PC ready-made tracing point graph API,

CodePudding user response:

This depends on your PC with what language development, have commonly associated libraries, plug-ins or API

CodePudding user response:

Tell me is too little, this a really difficult, on display, or don't understand,
Have experience, general display of 60 refresh, you in the program, make the code, what is the update a drawing board, and the how much because I don't have the unit, I don't want to delay to update the
I can also make this time, you can, I don't know, some of the specific time, I tested, the panel drawing speed is too slow, I try to use some GDI instance is also not line,
Multithreading, too, after have what method, what is the normal oscilloscope should update a screen for a long time,
