any help appreciated

When connecting to an external display i need to send a text string faster to a Diablo 4D systems display.

at the moment the coms on both host (arm F7) is set 115200 (on the Diablo the max speed is 600,000) anything above this speed the host will not communicate if a custom speed of say 200,000 is set in flowcode and the display i get no coms.

Why would this be please.. Is the custom speed working correct within flow code (i'm using UART connection not the VISI4D object but tested on both and the same issue no connection. 115200 and coms is fine.

Thanks.

Hi,
Could you post your project file, or a sample that shows the device, clock and UART settings at least?
Also what is your hardware circuit, e.g. are you using line drivers on the UART?
