dear sir ,
please suggest me that how i will identify that and show in the board is ADC and buzzer work when i load the hex code , reset the board and put jumper in the corresponding slot then what difference in the board that show me that ADC and Buzzer work properly .

Dear Sir,

Please check the following in your board..
Please ensure that proper jumpers are inserted in the corresponding slots..
The jumper settings are described in the datasheet..
For the working of the buzzer,the jumper - SPK has to be inserted..
The LPC 2148 support only one ADC..ie Variable POT..The LM35 connection pin (P0.27)is not present..
But the other ADC(P0.28) will work (jumper in A2DIN)..

All the modules are tested and are found working before the board is shipped..

The output of the ADC is in the LCD display..
When you rotate the ADC POT the decimal value from 000 to 1023 will be shown in the LCD first line..
The ADC is 10 bit, so minimum is 0 and maximum is 0x3ff (0-1023)..
The buzzer and external interrupt works simultaneously in the board.. ie for each external interrupt, the buzzer ON/OFF - toggles..
Put jumpers on Ext Interrupt and SPK for seeing the output of this program..


Please contact us for further doubts..
