Hello embedded people! We have a new project that may require operation at perhaps 105`C. This is well above what I am used to working with, so I have not paid much attention to "extended" temperature range parts. Now I need to find some! I am looking for suggestions for microcontrollers. Would prefer something modern and C (gcc) friendly, like e.g. the LPC2100 series I was going to use...

I want to connect the UART of the micro (LPC2100) to a cell phone serial port. Both devices should probably have short circuit protection but neither use +-15V true RS232 specs. Do I need a line driver chip between or is there a simpler (less cost/parts) way of making the connection? Thanks.

Hello Folks, The Philips ARM series had been out of my price range but the LPC2101 finally seems to be in reach, meaning under $2 in quantity. Now if one wants to try it out which kit would work? I'd have no problem if it was for another one of the ARM chips as they seem to be quite compatible. The only kit for the lower number parts I found at Digikey was the KS2106 LPC210x Kickstar...

I'm looking for the lowest power ARM7 MCU out there... one with the best mips/watt ratio. Its hard to compare the benchmarks used by various manufacturers since they measure active Idd in various ways, but the process technology (130nm, 90nm etc) is almost never specified. I've been looking at the LPC2101 which I believe is built with a 90nm process, but Ive heard there are intel parts that...

I can buy the LPC2101, 2102 or 2103 at Digikey, but the data sheet is still just preliminary and pretty incomplete. Any idea when Philips will update the data sheet with full information?

Hi everybody, I am looking for an ARM MCU with the following constraints (in the order of importance): - 4 channel ADC with > = 500 k samples/s - Price in 1k units < $1.50 - Frequency "as high as possible" but at least 32 MHz - 1 UART - RAM and Flash negligeable (1k RAM and 4k Flash would be largely enough). I found the LPC2102 from NXP which almost hit the price mark. I also got the im

Hi, Has anyone successfully programmed an LPC2103 using Rowley Associates CrossWorks for ARM and the ARM USB CrossConnect? It does explicitly support LPC2104, but it doesn't say anything about 2103. I know the LPC2103 is newer, but it also has less memory, and I don't know if that makes it impossible to support it. Any experience? Thanks in advance,

Hi, I've recently started development with a Philips LPC2103. I know Atmel has a site, AT91.com, which I found useful for AT91SAM stuff. I'm looking for suggestions or recommendations on websites/forums that discuss using the LPC21xx parts. I did the Google search already but ended up at sites that archive "the real" forums. If it makes a difference, I'm planning on using the ...

Hi, If you use Eclipse (the IDE, especially for embedded use, I would really appreciate your responses. I now have Eclipse(Zylin Embedded CDT) + OpenOCD talking to my LPC2103 (ARM7-TDMI), but I'm experiencing what seems like shortcomings in Eclipse. Maybe others here who use Eclipse for embedded development can shed some light. 1. Is there an "easy" way to automate the build, co...

Hello. I've a problem with LPC2103. I've two boards. The first-one is a Silica Demo Board with a Philips (with Philips logo) LPC2103. The second one is a home built board with only a NXP (note not Philps marked!) LPC2103 and just supplies and xtal. I've a Keil uLink and I use uVision3 for Arm. So, I can program both MCUs and everything works well. Unfortunately I can debug just only the ...

Hi, I am using: - NXP LPC2103FBD48 with ARM7 core. - Rowley Associates CrossStudio for ARM v1.7 Build 4. - C++. - Compiling with no optimizations. I have a mysterious bug that is causing, once in a while, a prefetch abort exception or a data abort exception. I suspect it is either the chip or the CrossStudio's fault, because commenting out one single line of source code that says "con...

Hi, I'm using Rowley Associates CrossStudio for ARM v1.7 build 4 (which relies on GCC C++ compiler) to develop a C++ program for an LPC2103. My problem is that I'm running out of code space (flash), mainly because some of the .cpp files I wrote have many class definitions, even though some of those classes are never instantiated from my application. I need to debug, so I need to keep all c...

Hi, I'm using Rowley Crossworks 1.7 Build 4 for my Olimex LPC P2103 and I have problems when I flash the board. When I debug it, even with the release version on it, everything is fine, but when I just load it and disconnect the debugger, nothing seems to work. Have you ever had this kind of problem and how can I solve it? --------------------------------------- Posted through h...

Hello, I am new at this forum and this is my first post. We are trying to control some servos with a microcontroller Olimex lpc2103. We managed to make all the necessary software and hardware, and everything is working fine. There is just one problem - there is some noice in the servos when turn on the transmitter. We decied to make some filter, but when we use the Kalman filter it works too...

HI all i need help regarding my project Secure Messaging Terminal on ARM 7.The purpose of this project is to design a mobile secure messaging terminal using a 32-bit ARM processor, LPC2104. Some of the symmetric encryption/decryption algorithms used for securing the data are Data Encryption Standard (DES), Triple Data Encryption Standard (TDES), and Advanced Encryption Standard (AES). ...

Hi Gurus, I am switching from AVR to ARM. Currently, I use an ATmega162 which is running out of code space (16kB) and performance. But I find it difficult to choose between Atmel's ARM (looking at the SAM7S series) and thePhilips LPC2104/5/6 series. I don't need many peripherals (yet). My current design uses an FTDI chip for USB, I could save that by using Atmel (Philips has no USB), but o...
