[hide]Objective
In this tutorial we will see how to setup a keil project to generate .hex file for LPC1768
Keil Setup Steps
Step1: Open the Keil software and select the New Microvision project from Project Menu as shown below.
Step2: Browse to your project folder and provide the project name and click on save.
Step3: Once the project is saved a new pop up “Select Device for Target” opens, Select the controller(NXP:LPC1768) and click on OK.
Step4: Select the controller(NXP:LPC1768) and click on OK.
Step5: As LPC1768 needs the startup code, click on Yes option to include the LPC17xx Startup file.
Step6: Create a new file to write the program.
Step7: Type the code or Copy paste the below code snippet.
| #include <lpc17xx.h> | |
| void delay_ms(unsigned int ms) | |
| { | |
| unsigned int i,j; | |
| for(i=0;i<ms;i++) | |
| for(j=0;j<20000;j++); | |
| } | |
| /* start the main program */ | |
| int main() | |
| { | |
| SystemInit(); //Clock and PLL configuration | |
| LPC_PINCON->PINSEL4 = 0x000000; //Configure the PORT2 Pins as GPIO; | |
| LPC_GPIO2->FIODIR = 0xffffffff; //Configure the PORT2 pins as OUTPUT; | |
| while(1) | |
| { | |
| LPC_GPIO2->FIOSET = 0xffffffff; // Make all the Port pins as high | |
| delay_ms(100); | |
| LPC_GPIO2->FIOCLR = 0xffffffff; // Make all the Port pins as low | |
| delay_ms(100); | |
| } | |
| } |
Step8: After typing the code save the file as main.c.
Step9: Add the recently saved file to the project.
Step10: Add the main.c along with system_LPC17xx.c.
Step11: Build the project and fix the compiler errors/warnings if any.
Step12: Code is compiled with no errors. The .hex file is still not generated.
Setup Bin File Generation
Step13: Click on Target Options to select the option for generating .bin file.
Step14: Set IROM1 start address as 0x2000. Bootloader will be stored from 0x0000-0x2000 so application starts from 0x2000
Step15: Write the command to generate the .bin file from .axf file
Step16: Now enable the linker option to use the IROM1 address from target settings
Step17: .Bin file is generated after a rebuild.
Step18: Check the project folder for the generated .Bin<ER_ROM1> file.
Uploading the Hex file
After generating the .hex file check the tutoial LPC1768 Tutorials for uploading the .hex file using flash magic.
