Hi,

   I am new to LPC2103. i bought this LPC2103 Controller for my project purpose.in this first i need to high/low the gpio pin.i saw the user manual provided in NXP.i saw the registers used for  GPIO. i used PINSEL,IODIR,IOCLR,IOSET registers.these registers are enough or any other registers are required for GPIO pin High/Low because i wrote the code using these registers and downloaded the code to micro controller through Python chip programmer.the code is downloaded but it is not working.

 

please let me know what else are required.

 

thank you

Eshwar
