At the moment I am busy with a ISP driver for AF. The dongle is connected to a self made PCB holding the DIP-28 µC for accessing its SPI ports and power supply. Two communication variants are in progres for the time beeing, a serial(RS232) and a parallel(LPT) one. Both of them are simplistic low-cost passive dongles for bit nibbling the information to the controller, they do not facilitate a µC themselves.
The serial version is based on this serial dongle, that is built up on a standard ISO PCB from only a few pices.
I decided to use this design because it is very easy to build from the scratch for even a novice. On the other hand this dongle needs a good old “real” COM port, not a USB2COM adapter end of a RS232.
The parallel version can be ordered at from Segor.de and is called BlueMP3/ISP and was meant for a CT project.
Please feel free to react on my poll in the Roboternetz Forum about which active dongle or PCB you are using at the moment, where active means “with µC”.
