    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&amp;nbsp; &amp;nbsp;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 &amp;nbsp;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.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;please let me know what else are required.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;thank you&lt;/P&gt;&lt;P&gt;Eshwar&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Eshwar,&lt;/P&gt;&lt;P&gt;Have you ensured that the programmer was able to properly download the code? The proper registers for GPIO manipulation are explained on Chapter 8 “LPC2101/02/03 General Purpose Input/Output ports (GPIO)” of the “&lt;A href="http://www.nxp.com/documents/user_manual/UM10161.pdf"&gt;LPC2101/02/03 User manual&lt;/A&gt;”&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;You could also refer to the following GPIO tutorial for LPC2148:&lt;/P&gt;&lt;P&gt;&lt;A href="http://www.ocfreaks.com/lpc2148-gpio-programming-tutorial/"&gt;http://www.ocfreaks.com/lpc2148-gpio-programming-tutorial/&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Hope this will be useful for you.&lt;BR /&gt;Best regards!&lt;BR /&gt;/Carlos&lt;BR /&gt;-----------------------------------------------------------------------------------------------------------------------&lt;BR /&gt;Note: If this post answers your question, please click the Correct Answer button.
