The application note AN52927 explains how to interface multiplexed segment LCD glass to PSoC3.

PSoC3 device is equipped with segment LCD driver which allows segment LCD glass to be directly driven without using any external components.

The driver supports LCDs upto 16 commons and can drive upto 768 segments. PSoC Creator tool provides Segment LCD component which simplifies the task of handling different types of segment LCD features such as 7-segment, 14-segment, 16-segment, Dot-Matrix and special symbols. This application note explains how to use Segment LCD component for a given LCD specifications.

The application note AN72382 introduces you to effectively use the GPIO pins in PSoC 3 and PSoC 5. Major topics include GPIO basics, configuration, mixed-signal use, registers, interrupts, and low-power behavior.

The any-signal-to-any-pin routing available with the PSoC 3 and PSoC 5 GPIOs can help optimize PCB layout, shorten design time, and allows for a large degree of solder-less rework. However, with this freedom comes a steeper learning curve than with a traditional microcontroller.

The application note AN65977 describes how to configure PSoC 3/5 applications to interface to an Analog Devices' TMP05 or TMP06 temperature sensor.

The TMP05 Digital Temperature Sensor Interface Component is a building block for thermal management applications. It enables designers using PSoC 3 to quickly and easily interface with Analog Devices’ TMP05 or TMP06 digital temperature sensors through a simple, serial 2-wire digital interface. The sensors can be daisy-chained together, minimizing I/O requirements on the controller. For more details on the specific functions of the TMP05 Digital Temperature Sensor Interface Component, refer to the component datasheet.

AN60590 explains the diode-based temperature measurement using PSoC 3 / PSoC 5.

The temperature is measured based on the principle of diode forward bias current dependence on temperature. PSoC 3 / PSoC 5 has on-chip 8-bit IDACs, and a 20-bit Delta Sigma ADC, which enable accurate, high-resolution temperature measurements. An external diode-connected transistor is used for temperature measurement.
