LPC2103 led blink

[eswarchand]

Hai,

I am using LPC2103 Microcontroller. Trying to toggle GPIO Pin for the same.

i used the code which was provided in several examples, the same is attached for your reference.

But, i'm unable to toggle the PIN.

Kindly suggest us if we have to add/configure any other registers.

I'm providing you our schematic for your reference, let me know if some pull-up/ pull-down configurations resistors are to be added.

Hai,

Thank you for your reply.

Here i'm trying to toggle the any of the GPIO Pin, its not required to blink the LED connected to respective pin.

we are using only PINSEL, IOSET, IODIR and IOCLR registers along with PLL configuration.

Please let me know if i have to use any other registers for making the GPIO pin Just High/Low.

Whatever LED you're trying to blink, I presume it's connected to some LPC2103 GPIO. There are multiple GPIO available on this part, but no one on this forum has any idea about your board design, or what example code you're using. Unless you can be more specific, no one will be able to offer advice.

Thanks and regards,
