EUART reliability |

Hi,
I've been reading some old posts regarding problems with the EUART on some of the high-end PIC 18s. I'm about to commit a PCB design using the 18F6722 and just wanted some thoughts before I waste my money
I plan to use both EUART ports in my design and I have v3.242 of the compiler.
Cheers,
Ed |

Just a thought.
Does that chip have a pinout that is compatable with others?
So are you commited to that chip?
I would use a chip that allows me lots of other options. Then in prototyping
stage you can find a chip you like. |

I don't think it does. The reason for using it was for the fact that it had two UARTs. Unfortunately I didn't have enough real estate to have an external SPI UART device and didn't have enough interupts for a software UART.
I think next time i'll do as you suggested and design in a 'backup plan'.
Hopefully I'll be able to use the two EUARTs without too many problems. I don't envisage doing anything too fancy, just the usual 9600, 8, 1,N and some interrupt driven data parsing. |
