Functions implemented in the presto.dll (PRESTO DYNAMIC-LINK LIBRARY) enable setting or reading of logical values at single pins of the PRESTO programmer. Various communication protocols can be implemented this way. QSetPins() function enables output pins control. QGetPins() function enables input pins reading. QSendByte() function enables a fast SPI Byte on the data and clock pins to be sent. If also reading is required, then the QSendByte_OutIn() can be used. Then there are also functions for the programmer features settings, for supply and programming voltages control and functions for reading of the returned values.

The library can be used with all PRESTO programmers, it does not depend on the version of the programmer.
