Good afternoon all,
I've started my first microcontroller project where i'm designing a USB interface to control 32 relays. I'm currently preparing to begin the construction of a prototype but would like to gain some advice from people who have experience with the PIC's UART.
Is it essential that an external oscillator or resonator is used to provide an accurate clock source for the PIC? I have read a present thation from Microchip that says it is essential, but is that really true? Could I get away with just using the internal RC oscillator?
Thanks for any responses,
Pete
