Schematic of JTAG and serial-over-USB
Tue, Jul 14 2009 23:37
As previously mentioned , the EPCS will take advantage of the FTDI FT2232H USB-serial converter and its integrated multi-protocol synchronous serial engine (MPSSE) support for JTAG for programming and debugging the ADuC7025 firmware. The second serial port provided by the FT2232H will be used in UART mode to provide a link for streaming data back to a PC. I envision... Read More...

Is that Instrumentation Amplifier needed?
Sun, Jul 12 2009 19:54
While writing the post on selection of the microcontroller , I got a little deeper into the capabilities of the integrated ADC peripheral. Initially I had just been relying on past experience with Analog Devices ICs for assurance that if the basic specs were sufficient then my needs would be met. But now I've discovered that the ADuC7025 ADC provides adjustable... Read More...

A Battery's Raison d'être
Thu, Jul 9 2009 23:32
Yesterday I put you all on notice that this embedded pneumatic control system (henceforth EPCS) will be battery-powered, gave an bunch of reasons that are inapplicable to this system, and promised to reveal the true reason today.  I also hinted smugly that the decision involved safety somehow.  Readers of The Hitchhiker's Guide (nope, no commissions...

Compromising Safety
Wed, Jul 8 2009 23:42
Hey, the catchy title must have worked because you're reading this post.  It is a little misleading though.  This post is about compromises and safety, but it's the compromises made to achieve safety.  If you ever see any feature of this system that appears it might compromise safety, please let me know! I feel a need to explain why the... Read More...
