Nizkocenovna USB naprava za zajemanje in generacijo signalov

TOME, MATJAŽ (author), Jankovec, Marko (mentor)

Namen diplomske naloge je bil izdelati napravo za zajem in generacijo podatkov, ki komunicira z osebnim računalnikom. Material in izdelava te naprave morata biti cenovno ugodna, kar je mogoče z uporabo modernih integriranih vezij. Naprava mora imeti 4 analogne diferencialne vhode z 12 bitno ločljivostjo, sposobne meriti vhodne napetosti med -10 in 10 V, 2 analogna izhoda in 8 digitalnih vhodno izhodnih priključkov. Signale mora zajemati z vsaj 100 tisoč vzorci na sekundo. Na računalnik mora biti povezana z vodilom USB, preko katerega se mora tudi napajati.

Abstract

The purpose of this thesis was to build a device capable of measuring and generating electrical signals. The device is controlled by personal computer. Goal was, to build this device as cheap as possible, by using modern integrated circuits. It has to have 4 fully differential analogue inputs wit 12 bit resolution and input range between -10 an 10 V, 2 analogue outputs and 8 digital input/output pins. It has to achieve a sample rate of at least 100 thousand samples per second. All communication with computer and powering has to be done over USB bus.
