This example program shows how to configure and use the A/D Converter of the following microcontrollers: * Philips LPC 2114/2119/2124/2129/2131/2132/2138/2194 After configuring the A/D Converter, the program reads A/D channel 0 and outputs the converted value using the serial port. To run this program... 1. Select the Device (Project - Options for Target - Device) 2. Build the project (Project - Build Target) 3. Start the uVision Debugger 4. Open the Serial Window (View - Serial Window 1) 5. Click Run (F5) 6. Click on the Toolbox buttons to change input voltages A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change. Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals grap
