Hi, Can you Help me about this problem: I want to have a second software uart But written in "C" and modified to work with INT0 or INT1 for detect receiver incoming data.. Maybe this i true way : www.atmel.com/.../doc3ab877f2ec329.pdf , but this code is assembler. Thanks and The Best Wishes !
Carefully select a processor that supports your hardware needs. the, unfortunately, waay too often case is that someone select a processor without eveluating its ability to handle the job. I see, today, no excuse for software UARTs, software I²C, software PWM, software SPI (except when you have silly things like "10 bit SPI), most cases of external memory, .....
yes, I know that sometimes it is difficult to obtain certain chips in Farawayistan, but the capable chips are legio, so, at least one of the bunch should be obtainable even there.
