Greetings, I got curious about all the "debate" about UARTs and crystals versus internal oscillators, so I did a quick and dirty model in a spreadsheet. I...
Dear all, I just figured out why my 18F452 wouldn't reach 40MHz, despite correct configuration settings in JAL (v4.62). Thought I'd document it here in case...
Greetings, What am I missing here? It seems like microchip went out of its way to be incompatible with existing 18pin prototyping boards. Is this a bug or a...

Hi all, I think that the 5% rule it's quite easy to understand. The most common format in RS-232 it's the famous "8,n,1", that is Start + 8_bit_data + Stop....
