In the files browser select thumb. The processor is running in ARM bit mode, the T-bit is clear and the instructions are 4 bytes long. We will look at the registers of the UARTs in more detail lpf2000.
Complete the for loop statement so it runs for the length of the printf string len.
This opens a terminal window within the simulator which displays the UART0 output. In this exercise we will setup a basic FIQ interrupt and see it serviced.
Evaluation Board LPC
Compile the code and download it onto the board. Step through the code and observe the following using the disassembly window and the registers window. Step through the code until you reach the while loop c. If you want to see the entry and exit mechanisms to the exception, it is best to lp2c000 the simulator and single step in the disassembly window. This way you can watch the program flow and the actions on the CPU registers.

If you set the program running lpd2000, the Pin1. You must raise the pin high again to stop interrupts. This button will generate a simulated pulse on to the interrupt pin. These scripts are based on the C language and are stored in text files. The script used to simulate the pulse is shown below:.

This script is stored in the file signal. In this exercise we will define an inline Assembler function to call a software interrupt and place the value 0x02 in the calling instruction.
In the software interrupt SWI we will decode the instruction to see which SWI function has been called and then use a case statement to run the appropriate code. As the first instruction in main add the assembler define which calls the swi instruction. In the disassembly window the first SWI instruction has lpc200 encoded with the value 1 at location 0xC.
The top 8 bits are masked off which yields a value of 1. This is used in the case statement to run the required code.
The content is based on a series of one day seminars held for professional engineers interested in learning how to use the LPC family as quickly as possible. In addition a comprehensive tutorial is included that takes you through practical exercises to reinforce the topics discussed in the main text.
By reading this book and performing the accompanying exercises, you will lpcc2000 become well versed in the ARM7 processor and the LPC microcontroller. The script used to simulate the pulse is shown below: Software Interrupt In this exercise we will define an inline Assembler function to call a software interrupt and place the value 0x02 in the calling instruction.
Declare the name of the C ISR function as a.
