Functional Description

Many embedded applications use the RS-232 interface to communicate with external systems such as PCs, especially when debugging. But in the PC world, the RS-232 COM port will soon disappear from most new computers, leaving USB as the replacement for serial communication. The simplest way to migrate a device to USB is to emulate RS-232 over the USB bus. The primary advantage of this method is that PC applications use the USB connection as an RS-232 COM connection, making it very simple to debug. This method uses a standard Windows® driver that is included with all versions Microsoft® Windows from Windows 98SE through Windows XP.

Features and Overview

• Selectable Positive and Negative Inputs
• Direct connection to interrupt controller
• Programmable power consumption
   

The CMP user module provides two comparators, each having an analog comparison of two selectable inputs (one is always a voltage reference). This user module provides flexibility of the inputs and of the function and routing of the outputs. The output of the comparator, and the neighboring comparator, can be combined with any 2-input logic function. This combinatorial output can be optionally combined with a latched value and routed to a pin output or to the interrupt controller. The input multiplexers and the comparator are controlled through the CMP user module. The combinatorial logic is automatically configured for typical operation when the user module is placed and can be changed through the Device Editor.

The LPF4 User Module implements a four-pole low pass filter. Damping ratio are functions of the clock frequency and the ratios of the capacitor values calculated automatically based on the user parameters preset (Corner and Sample frequency, Gain, Filter type). Any of the classical all-pole filter configurations (Butterworth, Bessel, and Chebyshev) can be implemented. You can also select custom filter configuration, enter values for complex poles. The corner frequency can be set very accurately or adjusted by controlling the sample rate clock. The filter output can drive the analog output bus.

Features and Overview

• 16-bit timer uses two PSoC blocks
• Source clock rates up to 24 MHz
• Automatic reload of period on terminal count
• Use terminal count output pulse as input clock for other analog and digital functions
• Interrupt on terminal count and capture
   

The16-bit TachTimer User Module provides down counters with programmable period and capture ability. You can select the clock and enable signals from any system time base or external source. Once started, the timer operates continuously and reloads its internal value from the period register when it reaches terminal count. The output pulses high in the clock cycle after terminal count. Events can capture the current TachTimer16 count value by asserting the edge sensitive capture input signal. In each clock cycle, the TachTimer16 tests the count against the value of the compare register for either a less-than or lessthan- or-equal-to condition. Interrupts are generated based upon terminal count and compare signals. The compare signal may be routed onto the row buses. The main between the TachTimer16 User Module and the Timer16 User Module is that the TachTimer16 provides both terminal count and capture interrupts. Timer16 gives you a choice of one or the other, but not both. The MSB block is the source for terminal count interrupt and the LSB block provides the capture interrupt. Another difference between the Timer 16 and the TachTimer16 is that the TachTimer16 has no parameter to choose the interrupt type. Interrupt types for both MSB and LSB are hard coded.
