December 2009 Meeting Notes

Coffee and a Chat


Canaan Hymns Digitization Project - CH Ting
"I am working with the China Soul Foundation to digitize 1250 hymns know as Canaan Hymns which were written by a Chinese farm girl. The Foundation will post these hymns on its new web site on January 1, 2010. It will post the hymns with numeric music notations and MIDI accompaniment. I am using SimpMusic Font to present numeric music notations. It is a very interesting system and totally compatible with Forth. I will play a few hymns sung by the author, Lu Xiaomin, from DVD and discuss the work involved in this project."

Digital Optical Transceiver Project - Samuel A. Falvo II
"Just last night, I completed the first link test - a continuous stream of '0' bits - with a user interface for the gathered telemetry written in Forth. Currently, the code's most interesting feature is its CRC-8-ATM calculation and the quasi-PPP-like framing. However, due to unforeseen problems in getting the USB link working correctly, it appears that I'll need to adopt a real HDLC interface to the PC. So far, I'm receiving zero errors on the link with the long loopy wires, but quite a number of errors on the USB link with its shielded cable and twisted pair core! I'm still confused about this behavior, but implementing proper connected-mode HDLC behavior will resolve this set-back."

"So, by the time the December SVFIG meeting rolls around, I should have a simplistic HDLC networking stack implemented in both the microcontroller and in ANSI Forth code."
