Hi Team,
If i used a PIC24 could i get a 1us interrupt running and still update a LCD display.
Thanks,
Wayne

Hello Wayne,
PIC24's can run up to 32MIPs and dsPIC33's can run up to 40MIPs.
So a PIC24 running flat out has 32 instructions every 1us.
A dsPIC33 running flat out has 40 instructions every 1us.
So if you keep your interrupt code fairly short eg just setting a flag or incrementing a variable then you should be ok.
