A customizable TP-UART interface
The concept behind the hardware and firmware and many more details are described in the paper " Design of an enhanced TP-UART based KNX PC interface" by Georg Neugschwandtner and Andreas Fernbach. It was presented at the KNX Scientific Conference in St. Katelijne-Waver in 2008. Two errata are known:
"An enhanced TP-UART interface board" by Andreas Fernbach (his bachelor thesis) also briefly covers the overall concept and requirements, but focuses on the hardware and firmware implementation. This report does not describe the most recent version of the PCB; for v1.3 (2010-03-01), the following things have changed:
There is some overlap between these two documents, but each contains information that cannot be found elsewhere. The "Notes" section on this website basically picks up where these documents left off.
The text files in the download package also cover the most important hardware features. The firmware source files contain extensive comments.
So far, no one has reported any. If you want, you may consider it a bug that we left out two capacitors that are recommended in the "typical application circuit" (C5, C6). Also, EXT PWR V+ on ACTIface could be connected between D3 and X3 (instead of after D3) to provide protection in case the power supply board is connected with reversed polarity.
Sorry, but we currently do not know of anyone who sells kits or assembled interfaces. If you feel like changing this, let us know so we can put your address here!
Get a JTAG adapter. The connector on ACTIface is designed for the TI "FET" adapters (and compatibles).
Download TI Code Composer Studio v4 (MCU Core Edition, TMDFCCS-MCULTD).
Then do the following - this is largely taken from page 10 (Section 1.2) in the "Code Composer Studio v4.1 User's Guide for MSP430" (SLAU157M):
