The Prog adapter is used to connect the Particle or the Spart to a programmer for reading, erasing, programming, debugging, etc. It is designed for the Galep III and Galep IV on which it has been tested. Make sure to choose the “DIL” package for the Processor. Make sure, that you put the adapter in the right position on the programmer. Some programmers give errors while deleting a particle plugged in the programmer. Ignore the error message. The erasing works nevertheless. Turn devices off before plugging them into the programmer.
