I am experimenting with the arm7tdmi-s in LPC2119 and trying to figure out what is in the
startup.s code to understand the vector interrupt system.
I have this curiosity where the labels like Reset_Addr and SWI_Addr are defined because they are not in the same file and neither in the header.
Appreciate any help.
thanks

The arm7tdmi-S processor has seven operating modes:
? User mode is the usual ARM program execution state, and is used for executing most application programs.
? Fast interrupt (FIQ) mode supports a data transfer or channel process.
? Interrupt (IRQ) mode is used for general-purpose interrupt handling.
? Supervisor mode is a protected mo

lpc2129 and lpc2148 belongs to which family ?
then do the peripherals in both controllers have same functions if they available in both ?for eg timers,uart etc..
what all the header files comes in both controller?
Both LPC2129 and LPC2148 are based on the arm7tdmi-S core architecture and members of the LP

All variants of the NXP LPC21xx series of ARM microcontroller share the same baseline features as they are all based on the arm7tdmi-S core, the major differences between these variants is an increase in Flash, RAM, GPIO and the addition of various peripheral hardware modules such as CAN, USB, ADC, Ethernet, etc.
For example, the only difference

Freescale offers ARM Cortex M4 microcontroller with dual speed 10/100 Mbps Ethernet MAC. What is the benefit of that?
Also if a controller like arm7tdmi from Atmel don't have Ethernet MAC support inbuilt, can we still have access internet to upload the data through tcp/ip.
Where we need ip stack?
A help to clarify the above points will be

A read the datasheer recommendation doesn't really reply the question.
Tahmid, have you used any LPC2xxx microcontroller (arm7tdmi)?

AT91SAM7X512 From ATMEL's website:
A member of the Atmel SAM7X series of microcontrollers based on the 32-bit arm7tdmi processor. It operates at a maximum speed of 55 MHz and features 512KB of flash and 128KB of SRAM. The 512KB of flash are split in two banks of 256KB. The peripheral set includes a USB 2.0 full speed device port , Ethernet

LPC213x/4x has a 32bit port but it is an arm7tdmi and not cortex.
Also LPC2103 has one full 32 bit port
I think you can use any cortex mcu, the speed is so high (50MHz or more) that even if you use tho sequential writes the result will be like if you changes them simultaneously for your application

HI,
I would like to implement this project but am a bit confused where to start from.
I believe i have to use two host controllers 1 for each pd right?FAT32 file system knowledge would also be required?.but is it necessary to implement an OS

Hello,
I need a JEENI or MAJIC-MT emulator manufactured EPI Tools Inc. urgently.
Can anyone sujjest from where to buy these? I want to use it to debug application on arm7tdmi processor.
Or if anyone want to sell one of these emulators then please let me know as soon as possible.
I'm interested to buy those emulators. Thanks

hi everybody,,
we are doing our final year projects using rtos.Now we started our project by writing a coding for simple application like blinking an led with different time delay.we are using arm7tdmi processor (lpc2148) .And we have an IAR Compile,,the version we used is v4.41a.
Now we don't have such idea how to make further move in our pr

LPC2148 (arm7tdmi) itself having ADC and DAC. You can work with. If you want i can send the code which is running in Keil version4.

lpc comes under arm7tdmi....for lpc i think keil supports.... lpc is easy for beginners... i think its better to start with lpc for learning basics in arm.....
There are many LPC family chips
arm7tdmi : LPC21xx/22xx/23xx/24xx
ARM9 : LPC29xx/31xx/32xx
CORTEX M0 : LPC11xx/12xx
CORTEX M3 : LPC13xx/17xx/18xx

Hi,
As ARM is a native 32 core (int is 32 bits), it is better to declare 32 bits data.
the compiler will put a 8 bits data in a 32 bits box avoiding to use align directives.
If you want to use less memory use the THUMB mode, is like a native 16 bit core.
this mode was previosly used on arm7tdmi.
Hope, i am not wrong because i worked 4 years on ARM
