| Abstract: | The purpose is to design a DSP-based pressure measurement system. We introduces the circuit layout and software are also given. The system using the TMS320F28335 of TI Company as the core processor and the piezoresistive level transmitter as measuring sensor. System can obtain the accurate data of depth of water fast under the circumstances like stormy waves and near the surface of water. System has the characteristics of swiftness reaction and good reliability. Besides the formal function, system can draw above water wave and the work mode could be controlled by PC. |
