Foot Controller Reference Design Using Analog Hall Sensors

TIDA-00642

Overview

This reference design includes an analog Hall sensor and op amp circuit that can be used for position or angle sensing, with the advantages of no contact and wear, high stability, and a wide sensing range. This design analyzes two configurations of magnets and Hall sensors. This design provides adjustable offset and system gain along with op amp circuitry to achieve the desired output offset and range.

characteristic

● Approximately linear response
● Adaptable to a wide range of magnet types and magnetic field ranges
●Has full-scale output capability from 0 to 5V
● Adjustable static offset and gain
● Low power RRIO amplifier stage
● Cost effective

44B0 interrupt problem
44B0 won't enter the interrupt, PND is set, which means there should be an interrupt, but it doesn't jump to 0x18 to get the address of the interrupt service routine. INTMSK is also set as required. I
