Sorry for Late reply,

Ttelmah, It's working with H4 using external clock.

Thank you all

Similarly, if you have timers programmed, you need to change these, and also, after changing the clock, you need to call 'setup_uart' with your required baud rate, so that the uart dividers are reprog ...

temtronic,

Thanks for reply. The problem is data receiving by UART using "External Clock". When I use internal clock everything seems working fine.

If you can lose the OSC1 pin, just select HSPLL, instead of EC_IO, and run at 14745600Hz. Otherwise switch to a faster oscillator.

In PIC18F25k20
Fuses: LP,XT,HS,RC,EC,EC_IO,H4,RC_IO,INTRC_IO, ...

Hi,

I am using pic18f25k20 with external oscillator. The problem is my UART transmit works fine but when it comes to receiving it won't receive proper data or skips data.

If I use internal clock ...
