What level shifters are needed to convert from 5.v to 3.3v ?
for example on a propeller a simple 1k resistor is needed (the diode is inside the propeller)
is it sufficient for a tinyfpga A2 ?
or do I need some specific chips… ?
among the idea:
- drive an apple Disk II drive by a tinyfpga A2
- convert V/HS 20 Khz into a VGA signal
