Analizador Lógico con Tarjeta demojm o demoqe de Freescale

http://www.pemicro.com/fixedlinks/DEMOToolkit.cfm#1




The DEMO board has a built-in two-channel logic analyzer. This analyzer allows the IN0 and IN1 signals to be captured by the PC and displayed for the user. The IN0 and IN1 signals may be connected to any of the MCU signals which the user would like to view. By default, they are connected to the PTC0 and PTC1 pins of the MCU by jumper J11. At the time of this release, the logic analyzer runs at a capture rate of 10khz.
This PC-based application is used to display the logic analyzer data on the PC. The logic analyzer data is displayed in real-time and each waveform may be paused, zoomed, and printed.
If the microcontroller-based Quick Start Application is programmed into the MCU, the IN0 channel will show the PWM output on pin PTC0 whose duty cycle is controlled by the potentiometer (W1). The IN1 channel shows the PWM output on channel PTC1 which drivers the buzzer.
