Hello,
I'm currently reading voltage data serially via USB (COM port) and I'm trying to use the "Write to Measurement File" block to log some of the data that gets passed through.
For both cases, when using the Write To Measurement block:
- I experience lag in the rate at which data gets plotted to the Waveform chart and,
- The written file ends up with data that has duplicate timestamps with different values.
I've searched for similar issues in the forums but I couldn't seem to find anything relating to this issue. Is this a known issue? How would one go about ensuring that a set time delta restriction is in place?
Any insight would be appreciated.
The VI configuration and .lvm buffer are attached below.
I am sampling at a rate of 1 kHz (PIC18F2550) and sending the samples out via UART (19,200 baud rate) protocol to be plotted on a waveform chart.
