loss of data acquired from UART port for baudrate of 50kHz

Hello;

In my program I have labivew acquire data from a microcontroller specifically from the integrated  ADC integrated.

 

when  tring to reconstruct the signals injected For a transmission rate of 50KHz  the data acquired by Labview   are wrong

the microcontroller is sending samples each (12 bits) on two 8-bit part and then another 8 bits in labview  a concatenation of the two byt gives us the sample sended by the microcontroller 

. So I am asking if the visa read  for serial communication this it may not work for relatively high frequencies???

Thank you for any help

Hello,

NI-VISA should not be limiting communication at that rate. NI-VISA does not limit the range of rates you can use; the device itself may not be accepting some of the baud rates you are using.

Take a look at this document for some of the standard baud rates and some more information.

You may need to include the code so that we can make more sense of what you are trying to accomplish in LabVIEW.
