Electrocardiograph Realized on PSoC Microcontroller

U ovom Završnom radu razvijen je jednokanalni elektrokardiograf. EKG pojačalo je izvedeno pomoću izrađene tiskane pločice i PSoC 5LP mikrokontrolera. Na ulaz tiskane pločice dovodi se analogni EKG signal koji se pojačava i prosljeđuje PSoC-u. Nakon analogno-digitalne pretvorbe i filtriranja, signal se šalje na obradu u MATLAB. Elektrokardiograf komunicira s osobnim računalom korištenjem USB sabirnice. Za upravljanje elektrokardiografom razvijeno je korisničko sučelje u MATLAB-u koje omogućuje prikupljanje, prikaz i pohranu mjernih podataka. Također je razvijen algoritam koji vrši detekciju R zupca.During this Bachelor Thesis, one-channel electrocardiograph was developed. ECG amplifier was implemented using printed circuit board and PSoC 5LP microcontroller. Analog ECG signal is connected to the analog input of PCB where is amplified and then passed to PSoC. After A/D conversion and filtering, signal is sent for further processing in MATLAB. Communication between ECG and PC was established using USB. The graphical user interface for controlling ECG was made using MATLAB and allows user to gather, store and display measurement results. There was also developed an algorithm to detect R peak
