advice needed...

[TKS]

hi i need to control 3 servo's (Jmubo RC Model ones..)
they need to position 2 of them using AD, the other one by buttons..., the 16F877a only has 2 ports for HPWM, the 18F448 has 4...i need to run the servo's at 50Hz...

who has advice to do what??

Should the 18F448 can do the job soow low??

Should the 16F877a can do 2 in hardware mode and one in software??

advice would be apreciated...

The PWM isn't much use for feeding servos (try working the relative highs and lows out), but you can do a considerable number of them in software.
