Hi

I have two simple questions:
(a) Can a software UART transmit at 57.6kBaud using a 12MHz Xstal? and What is the fastest that the software UART can transmit with a 12MHz Xstal?
(b) If I have va ...

Hi Ttelmah

Thank you for a thorough explanation. I have a lot to think about!

Have you had any experience with the small surface mount Xtals of the quartz variety?

All the best

Hi

I have been using 12MHz Xstals that have a package HC49 (through hole) with my PIC projects.
I was wondering if there are any smaller, surface mount Xstals that I can use with my PIC18LF4550?

Hi

I am using the PIC18F2550. I was wondering what is the fastest that data can be transferred using RS232 (I am using a 12MHz Xtal)?

Alternatively, using USB, what is the fastest that data can ...

Hi Wayne_

Thank you for your reply.

Can you please tell me if there is a way to prevent the EEPROM from being re-programmed in the *.c code? Is there a line/command I can add?

It turns out th ...
