In this tutorial, I am going to show you how to create project using Keil uVision4 for LPC1768 Microcontroller. I believe you have already installed Keil µVision and Co-MDK Plug-in + CoLinkEx Drivers required for CoLinkEx programming adapter. If you are not yet then please follow previous tutorial.
This is probably first tutorial in this series where we’ll create fresh new project from scratch and program NXP LPC1768 Microcontroller. Lets get start to create new µVision project to blink LED by adding simple delay. First create a test folder on desktop to manage your project and related files. There would be several files to take care during whole procedure. Copy system_LPC17xx.c and main.c file into test folder. I will explain to you later on about what are those files?
Launch/Open “Keil µVision4” default workplace and then go to “Project” –> “New µVision Project” and then browse your project into test folder on the desktop and give it name as blinky and hit on “save”.
At this stage we get pop-up box onto the screen. There we have to select “LPC1768” from NXP and then hit on “ok”
Now it ask you to copy “Startup_LPC1768xx.s” and hit on “Yes”
Now right click on “Target 1” in project pane and click on “Manage Project items…”
Here click on “Add Files…” and select system_LPC17xx.c and main.c file. Now we just need to hit on “Add” button and then Close that dialog box and hit on “Ok”
At this point we need to configure programming adapter CoLinkEx. So click on “Options for Target” on menu bar and then go to “Debug” –> select “CooCox Debugger” from drop down menu.
then hit on Setting –> choose SYSRESETREQ from drop down menu –> hit on “Ok”
Now go to “Utilities” –> uncheck “Use Debug Driver” and then choose “CooCox Debugger” from drop down menu.
Here again we have to go to “Setting” –> click on “Add” –> and choose “LPC17xx IAP 512kB Flash” from list and hit on “ok”
Finally we have done with all house keeping stuff for our project and the only thing left is to build and load output file into microcontroller. So after returning back to our workplace. Hit on “Build” icon on main menu and once we build successfully without any error. Then simply hit on “Load”. And that’s it…!!!!
Now we can see that LED connected to P1.29 is blinking with delay. Download complete project by simply Click Here. I think this is enough for today. In next tutorial we would discuss more about program i.e main.c file and also will have little fun with setting different delay. I hope you will find this tutorial educational. I wish you great time and see you in next tutorial.
