I said:
Steve's answer requires least work in the 8051, but needs extra hardware (the MAX7221) Steve M. Taylor said:
...and least external hardware: one 7221 against 3 ls47s But I said the LS74s were a bad idea anyhow! Depending on the chosen displays and 8051-derivate, it could be possible to connect the displays direct to port pins - so that would require no additional hardware! |
