Using the LED, the Potentiometer and the Push-Button in a pre-programmed
example
There is an example program preprogrammed into the device sample that came
with your PAB90x-1 board. The source code is included on the CD, in folder
"LPC901_2_3 LED blinker and SD ADC".
The software blinks the LED with a frequency that depends on the position of the
potentiometer. While the push button is pressed, the device is held in Reset.
To run the software, do the following:
(please also see "1_minute_demo_setup.pdf" on the included CD):
• If you already erased the sample that came with the PAB90x-1 board:
Program the "D:\LPC901_2_3 LED blinker and SD ADC\blinky2.hex" file
into the LPC90x as described in section 3.
• Connect the KBI, LED, RC_CHARGE, V_C and V_AN header pins to the
LPC90x as described in the image below:
