Bs2sx
O.A.A.

Hello,
I have developed a home brew BS2E and it is fully functional.For circuitry see www.osmanardali.com/BasicStamp/BasicStamp.htm.
When I try to run it at 50 MHz as BS2SX by changing the 20 MHz resonator/X-tal to 50 MHz, the test program I had uploaded at 20 MHz continues to run with the 50 MHz X-tal but Windows Basic Stamp Editor (version 2.1) gives "No BASIC Stamps found" error message at the RUN command.
Also instead of the 50 MHz X-tal when I insert a 50 MHz resonator (obtained from Parallax) and a 5 pF capacitor between pin 28 and earth the test program stops running.
Help would be greatly appreciated.
