Setting Baud rate in LabVIEW FPGA Realtime for serial communication with UART.

[roxor14]

I am sending data over RS-232 in real-time vi at baud rate 115200. because of this, the minimum loop time is limited to 6ms or so. in trying to reduce this time, I tried to increase the baud rate in the ni-max visa panel to 921600 and set the same baud rate LabVIEW rt vi. everything compiles fine and even the loop delay has decreased but there is no data coming on the UART channel.

we are using a UART-to-USB converter and checking UART channel data using the "screen" command in ubuntu on a laptop.

Any ideas about what might be happening here?

Dear roxor14,

I did it work when the baud rate was 115200? It is the maximum baud rate UART can have, maybe that is the problem.

best,
