For now we have only a simple parallel port programming interface for In-System-Programming of Scenix/Ubicom SX48/52 microcontrollers. Schematic below. The circuitry is very simple, you can replace the transistors by any comparable types. The JP1 connector has a SX-Key compatibe pinout, you can plug this for example on the USBIO24 modules from

Before accessing this interface first stop all services and unload all kernel drivers accessing the parallel port.

Then load the lowlevel driver module by entering in the driver directory:

# make insmod

Now you can read and write the EEPROM of the SX48/52 using the scenix2 program located in the tools directory.
