MSP430F42x Single Chip Weigh Scale
A single chip pocket weigh scale is implemented using a resistive full-bridge sensor and a fully-integrated MCU solution using low-power design practices. The measurement results are obtained using the MSP430 on-chip sigma-delta A/D converter and shown on an LCD display. The portable device is directly powered from a 3-V battery. A two-point calibration mechanism for offset and gain calibration is provided.
