I have a chip that needs a 4mhz crystal or resonator or a TTL clock, is it possible to use one of the I/O pins on the BS2 to create a clock, thanks

    Hello,

    ·· The BASIC Stamp would not be able to output a square wave in the MHz range.· You can pick up a TTL Oscillator from Jameco or DigiKey.· These require only 5V and ground and have a TTL output.· I used to use these at 4 MHz for the Z80.· They're not too expensive and have a DIP footprint.
