The MEASURE program uses the analog inputs of the P89LPC935
to implement a datalogger. This example shows how you can
use signal functions in uVision to simulate a signal coming
into one of the analog inputs of the P89LPC935 controller.
Introduction
Matlab is an ideal tool for simulating digital communications systems, thanks to
its easy scripting language and excellent data visualization capabilities. One of the
most frequent simulation tasks in the field of digital communications is bit-error-
rate testing of modems. The bit-error-rate performance of a receiver is a figure of
merit that allows different designs to be compared in a fair manner. Performing
bit-error-rate testing withMatlab is very simple, but does require some prerequisite
knowledge.
this is a digital intercom projects using ADC PWM and UART interrupt.
you take the value from mic enter it to ADC and then send serially to the other microcontroller which receives the data and transform the digital data into analog data by PWM which is connected to speaker
This article covers many of the fundamentals of analog video. Video is defined for our purposes here as "moving
pictures." Still imaging, like what is found in digital still cameras or scanners, is not covered. The requirements
for still imaging do have a lot in common with those for video, but the differences are significant enough to be
dealt with as a separate discipline.
