Hi Everybody! Im a new in the world of ARM, im previosly use 8051-compatible form Atmel, Z8000 & PIC's. I need to choose between NXP LPC2148 and ATMEL AT91SAMS256, two uC that seems to be very similar. I live in Argentina (by the way, sorry for my bad English!), and the cost of OLIMEX Starters Kits are similar for the two options. One thing I love from ATMEL is th LOW Prices, but...

I was given a atmel SAM-ICE which is used on the atmel arm 7 controller. I wonder will it work with the nxp evaluation boards ? I am thinking about getting a keil eval board. Will it work ? Thanks!

Hi- I am having probles with the LP32138 SSP (SPI) interface to an Atmel dataflash (AT45DB161). I believe it has to do with the chip select implementation. To read the status register of the Atmel dataflash, for example, the device requires an opcode 'write' followed by a 'read'. The write works fine, but the 'read' fails. I believe it is failing because the chip select gets deasserte...

This is Me http://www.linkedin.com/in/davidrwilcox I am currently working on my Graduate thesis. I chose an ARM7 core processor, LPC2148, for my project. I was wondering what the best free/ish compiler loader out there is. I have used Atmel 8051 with AVR Studio. I was looking for something comprable so I could watch ports and debug while building programs. Any suggestions? I ha...

Hi All, I would like to introduce myself. I am Vihang from India. I have been working in field of embedded system since last three years. I have worked on 8/16bit microcontrollers from ATMEL/PIC. Now first time I am trying my hand on ARM(LPC2387) and I am very excited about it. I am going to develop (H/W + S/W) system with following things. Hardware Requirements: 1. LCD displ...

Hi, i need to develop the firmware update for a project and was thinking on u= sing the IAP. Basically i would made a second bootloader for our code, this= boot will never be erased so even if a power fail, or any other (Murphy=B4= s law like) thing hapenned during the update, i=B4ll be able to restart it = later. Here=B4s the problem, i=B4ve suffered a lot with AT89S8253 (Atmel) where ...

I am trying to port a basic USB CDC stack from an AT90USB162 to the LPC2148 (rather than paying for something like an FT232RL), and it seems on the atmel chips you can use PROGMEM to store variables in flash memory rather than using SRAM (which is good since the AT90USB162 only has 512 bytes of it). I was wondering if there is a straight forward way to do the same with an lpc2100? All of the d...

Hi all, After successfully programming Atmel uC, I am now moving to LPCs. I'm a DYI guy and after successfully destroying my parallel PC interface trying different adapters, I find myself forced to look for a USB or serial (JTAG) programmer. I'm not sure what I need as I'm just starting to understand ARM, and never used JTAG before. What I'm looking for is a very simple schematic of an a...

Noob here, I'm just starting out with the LPC2368 using the Keil compiler software. I've come from using Atmel chips and the way of defining interrupts on pins was somewhat easier... I was wondering if anyone out there could give a short tutorial on how to define one of the GPIO pins, say P2.15 as a falling edge interrupt? I've been beating my head against a wall trying to get it to work....

Has anyone seen anywhere a GPIO pin schematic for the LPC17xx devices, i.e. the circuitry inside the pin. I have a feeling I have seen it in the datasheet/user manual but now cannot find it. Or I might be thinking of Atmel AVR. I really just want to know what protection diodes are on the pins and how they are connected - I am curious about what happens when you put 5V on the 5V tolerant pins an...

At last! An ARM controller with all of the peripherals I need (with the possible exception of CAN). For the last 18 months I have been in search of the holy grail when it comes to ARM + peripherals... and it seems that NXP have finally found it for me. My research has shown that (previously) ARM9 processors by the likes of NXP, Cirrus Logic and Atmel all had one key component missing - suc...

I'm back on my I2C problems since I was pulled off the project for a month or so. I'm still having some problems. The problem I thought was I was trying to address a 5V RAM instead of a 3.3V RAM. I have now a couple of ATMEL 256K serial RAM - 2.7V to 5V. I am still having trouble with understanding the status of the I2C bus. It appears I am getting the correct status, but even when the R...

Hi All, I've developed a few GPS logger solutions around the LPCs and it's frustrating that most GPS modules have an ARM7 core inside already. The latest u-blox modules have SPI, RS232 and USB ports right off the GPS module which is everything I need but I still have to bolt on another LPC to do a little file system stuff and add a few sensors. Atmel just announced a new micro with...

Hello all! I'm having some problems setting up ssp clock speed on a LPC1114. I want to set it to 15 MHz to communicate with an ATMEL AT45DB011D flash memory, but only get 3, no matter what I do, and I'm sure it's not a software problem since I already have this working with an LPC2368 at 15 MHz peripheral clock. On the other hand, AT45DB011D electrical specifications does not specify a minimum ...

Anyone used the ATMEL EEPROMs? Just a curiousity question. I was wondering why the 8 byte write limitation on a single write (page)? Not only that, if you write somewhere in the middle of the 8 byte page, you have to end the write at the end of the page and issue another write at the beginning of the next, even though the addresses are sequential. The Read has no such restriction. Why i...

Hi, I am in a process of selecting a Cortex-M3 micro for a new project. One of the criteria is lowest possible power consumption in run mode. So far I was able to determine (based on manufacturers specifications) the following values for uC families: EFM32 (Energy Micro) - 0.18mA/MHz Stellaris (TI) - 0.56mA/MHz STM32 (STMicroelectronics) - 0.625mA/MHz SAM3S (Atmel) - future device - 1.15m...

Hi to all, We are facing an issue nothing technical but affecting the development task. That is we have two serial Flashes on our product interfaced using SPI and SSP, one is used to store the firmware using file system another stores a raw memory which is the user settings and some editable data. Then we have another SD card to store firmware using file system as an alternative option. ...

I'm trying to get a system up and running using the Embedded Artists LPC2468 development board with a Macraigor usb2Demon using the GNU toolchain and Eclipse. Macraigor does not have any sample code for the board. I have gotten it to work on an Atmel AT91M55800 board and tried modifying that GBDINIT file to use on the LPC2468. The initial problem is starting up the Macraigor OCDRemo...

TNKernel v.2 now has mutexes with Priority Inheritance Protocol and Priority Ceiling Protocol supporting. Few additional API functions has been added mostly for create/delete objects, terminate tasks and also for dynamic changing task's priority. Additional processors (Atmel AT91SAM7S and STMicroelectronics STR711) ports has been added to examples. There a
