ESP8266 Notes

I upgraded from Ubuntu 14.04 to 18.04 then found the Total Phase Data Center software for the Beagle USB 12 no longer works. strace shows a number of missing shared libraries. The solution is to copy the missing libraries from 14.04 into the Data Center local library directory. data-center-linux-x86_64-v6.73/lib/ libpng12.so.0 libgstinterfaces-0.10.so.0 libgstapp-0.10.so.0 libgstpbutils-0.10.so.0 libgstvideo-0.10.so.0 libgstbase-0.10.so.0 libgstreamer-0.10.so.0
