Abstract:
The topics of this paper deal with a multi parametric acquisition system developed around a four input Analog to Digital Converter working in CAMAC Standard.
The acquisition software is build in MS Visual C++ on a standard PC with a USB interface. It has a visual interface which permits Start/Stop of the acquisition, setting the type of acquisition (True/Live time), the time and various menus for primary data acquisition. The spectrum is dynamic visualized with a moving cursor indicating the content and position.
The microcontroller PIC16C765 it is used for data transfer from ADC to PC; The microcontroller and the software creates an embedded system which emulates the CAMAC protocol programming the 4 input ADC for operating modes (“zero suppression”, “addressed” and “sequential”) and handling the data transfers from ADC to its internal memory. From its memory the data is transfered into the PC by the USB interface. The work is in progress.
