Labview Serial Binary Data Stream

Read Arduino Serial Output string with Labview. Read Arduino Serial Output string with Labview. Mrap recovery vehicle specs. If you're sending binary data. How can I use binary or hexadecimal data with the LabVIEW VISA functions? Writing Bits to the Serial Port Instead of Writing ASCII Strings; Other Support Options. Iv been trying to decode the output of a serial mouse to a binary file to then. If you want to view binary data in. LabVIEW General; ascii to binary.
Iv been trying to decode the output of a serial mouse to a binary file to then obtain the coordinates of the mouse. I managed to determine these by using the aquire mouse functions last week but my boss has said that i need to use the serial port of my computer instead so that i can then ultimately run two mice in parallel. From searching through examples on NI's website i cam across Convert ascii strings to individual bits.vi but when i come to save the output into a excel document all i get are squares and an error message from excel. (nothing new here!) Could someone point out to me where im going wrong please? 1470/snapback Cheers. I also need to separate the string into 3 byte packages.
My algorithm is to firstly look for the string header of 0x40 by anding my string with 0xc0. If this is true then capture the following 3 bytes.
Binary Data File
If not then these then also must be mixed and matched into an appropriate order. This i know can be done by shifting the various bits to where needed.
Ive looked for some vi's on the NI.zone website to no avail but thats probably because i dont know what im looking for. I start with a string data type and my hopefull output is a list of my three bytes in their correct order.
Can anyone help? 1460/snapback I cannot see your code (not all of us have 7.1) but if I understand your question corectly you might be using the wrong tool. The reason excel doesn't like the 'bits' is that they are non printable characters. Each character received in a string like this represents a byte (8 bits) that can be interpreted as an ASCII character (0.255), some of which are the characters A, a, 1, etc, but many which are non printable. You can convert tthe string you receive into bytes using the (A) tool in figure below, alternatively you may want to see the ascii 'hex' representation of the string (B). What I think you need to do is 'decode' the array of bytes into the numbers, then write the numbers as a string to file ©. Cheers, Alex.
