pic32mz EF UART

Can anyone give me the configuration and code for sending a character in UART?

I am using Pic32mz EF starter kit and MPLAB X-IDE v5.15.

I tried a code but it is not giving out any UART in tera term or putty.

}
}

I think there is a problem with my configuration bits and Baud rate. Can you please help me in setting the correct baud rate and configuration bits?

Thanks & Regards,

I'm having a problem with a project of mine that I haven't figured out yet (I get garbled data), but here's what I do see in yours. You will need to set the TRISx bits for the TX and RX pins to OUT and IN, plus you'll need to map those UART functions to the physical pins through U2RXR and RPDx registers. You also need to clear the bits for those two pins to digital in the appropriate ANSELx register(s).
