Hello all. Till now I coded all my projects for LPC2129 (ARM7TDMI MCU) using Keil C compiler. I have very good assembler skills so I would like to code some assembly. The problem is:: When I try to compile something simple *********************** AREA MAIN,CODE MOV R1,#3 END ********************** Error are: *** WARNING L23: UNRESOLVED EXTERNAL SYMBOLS *** ERROR L128: REFEREN...

1. I try to send message on CAN with 29 bit identifier, for example with walue 99dec (63 hex) and I receive message with identifier 0x00630000 it doesnt seem to be 29 bit but 11 bit??? 2. I looked int setting acceptance filter like in BlinkyCAN example from philips but it doesn't work: Does anyone have any idea why (in this example I'm using standard identifier of 11 bits)? // Setup ...

I'm looking for compile ucos-ii RTOS port to the Philips LPC2129 with the GNU Compiler. The code available on www.micrium.com site is, instead, intended to be used with the IAR Compiler. First of all, I need to translate the assembly code for IAR Compiler to the GNU Compiler syntax (GAS, if I am not wrong), and I'm searching for a IAR Assembly User Guide but without success. Am I not able or...

I'm interested in purchasing a demo board for an ARM7TDMI-based microcontroller (a Philips LPC2129 to be exact.) That's fine with me, it only costs ~$150. I want be able to debug it with a JTAG debugger, so ~$300 debuggers by Keil and/or Nohau come to mind. Salespeople tell me that I can't just stick the Jtag onto the demo board, but that I would also need to buy their full $2000+ develo...

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'm working with the LPC2119, and need to program the Flash via IAP, it's kind of an upgrade to the flash code. -I'm using the Interworking feature. -I start making an executable region for the flash programming in RAM, so i can erase the flash and still working, BUT in someway, the code in the RAM has references in part of the ROM, they are the veneers, and as i erased the flash, i can't f...

Hi, I have design using Philips LPC2114 processor. Its battery driven so minimal power consumption is essential. Problem is that even with cpu power down the circuit still uses about 2-3mA. :I I have measured that almost 2mA goes to CPU so something there is not right. I've read erratas and application notes and lots of other stuff and done the things they suggest to get power consumpt...

We'd like to use the Philips LPC2114 in a new design (we need 8 capture channels, a serial port etc.), but all the dealers say the lead time is 24 weeks. We can't possibly wait this long to have a pilot series manufactured. Is there any place where we could buy, say 50 of these MCU's _now_ or do we need to use some other chip? I would consider using the new Atmel AT91SAM... chips, but the...

I am designing a board using a Philips LPC2114 (nice chip). It uses 1.8v for the core, 3.3v for I/O, and I also need 5v for some other circuits on the board. None of them use much current. The power supply is a 12v battery. What is the best way to get these voltages, without running down the battery? Is there a single device, such as a DC/DC converter that can produce these voltages? ...

Hi, I have started evaluating the GNUARM tools for a LPC210x target (little-endian) and come across the following which is odd to me. With ul defined as: unsigned long *ul; The function function1 returns a pointer to void. For the following line, ul = ( unsigned long * ) function1(); GCC uses R0 to return the function1() result which is 0x40000625, the instruction: STR R0, [R4,#0...

Hello, we are looking for development tools (IDE and simple In-Circuit Debugger) for the Philips LPC210x (ARM7) controller family, particularly at the lower priced end. At the Philips homepage, several systems are listed (mainly from the greater vendors like Keil, Nohau, IAR, Ashling etc.). Can someone recommend a good package to look at? Maybe there are some more makers of "smaller" de...

I want to set a colleague's son up to work on some simple ARM projects on an LPC2106, using material I have on hand. I have plenty of EVBs etc lying about, but the only JTAG adapters I have are a few Keil ULINK2s and a Rowley CrossConnect. Is there any free debugger that works with either of these adapters? Thanks.

Greetings, I am having a problem understanding how to setup an SMD ceramic crystal to work with an LPC2106 micro. Maybe its the crystal part that I do not get. What is the load capacitance? Is it the capacitance that the crystal exerts on the circuit? How do I pick the capacitor values required, and how do I know that they are needed? The part I am looking at is http://www.abracon.com/R...

Greetings, I am reading mixed information about the ability to program the 2106 using a parallel port wiggler. Some say that it is only possible to program the device via RS232 but others say that it is possible to do the JTAG programming. What am I missing? What do I need to have to be able to use JTAG for programming the chip if possible? Thank you, -- A

We have at work a student doing his internship at this moment (Undergraduate in programming / ICT with a good knowledge of hardware) We've got this student working on simple embedded software on different targets (LPC2106, Rabbit, PIC's), altough the code he is writting is working, he does have problems in applying basic embedded / 'real-time' concepts. He has dificulties implementing s...
