Mapping my first microcontroller

cirokenzie — Tue, 11 Apr 2017 20:17:09 GMT

Hello,

I know it must be very easy for all of you out there, but I'm a completely new to micro controllers so please bear with me. I did a lot of researching but there is no information about LPC811 out there.

So, I have an LPC811 micro and I would like to program it to blink an LED. Can anyone help me with how to control pins of this controller? All the sample programs I see are related to the LED of a particular evaluation board using 812 the OM13055. I dont want to use the evaluation board, I want to control an LED independently using a breadboard.

All I need help is mapping the pins a little kick so I can hopefully move on my own.

Thanks,

Ciro.

Hi Ciro

Maybe the pin configuration tool can help you:

tutorial video:

The tool is geared towards LPCOpen, but can also help you if you are using Code Bundles by identifying register bit field settings.

Also, this isn't an NXP tool, but might be helpful:

I would recommend you this course Embedded Systems Course| edX It´s free, you dont have to buy kit, just look at the videos and you will have some basic knowledge. It is different MCU, but the basic principles are same - GPIO has some clocks, direction register etc. in this course you will see basic principles.

This course is for TI devices, so is not generally applicable to NXP devices. If you want to look at some generic ARM Cortex info it might help but I don't think that was the original question's intent.

In case some readers come across this posting - we now have support for pin and clock configuration for all LPC800 series devices in MCUXpresso, when using MCUXpresso SDK.

We've been doing a class on using the pin config tools to generate a custom SDK... new users might find this useful: https://community.nxp.com/docs/DOC-343310
