I had been feeling so sleepy today that I wanted to try VISA (Virtual Instrumentation Software Architecture) to read the data from my PIC16F877A microcontroller using the LabVIEW software. Well I did it in a whopping 5 minutes!
Well, the data that is being read is shown in the snapshot below:
The number of bytes to be read is controlled by the user. However, the data that is being read is displayed in a marquee sequence.
For e.g: When you choose to read a 4 byte data, the fourth byte of data is replaced by a byte with a shift towards the right when the latest byte of data arrives at the first bit (left side).
So your data hello would be read as : h –> he –> hel —> and so on. I captured a snapshot when the indicator read ‘hello’ 😉
However, my reading process was interrupted by an error log created everytime. I added an error out constant which made things smooth!
I shall try adding some features to this VI in future.
