... Hey Well I solved my problem... I calculated a wrong divisor. unsigned int divisor = pCF / (16 * baud); //Works in Keil, but not GNU should be: unsigned...
Hi Guys, I'm new to MCU and software so go easy on me, I have a project with LPC2106 and I want to use it to control a different component taht only have a...
Hi, The LPC22xx series would be better for this, because they have an external memory controller. But if you only have one or a few devices that do not need to...
I have done something like this, but unfortunately can't release it. This is a pretty straight formward thing to do. * Establish comms with PC via RS232. *...
I noticed the example makefiles that come with Aeolus Development's newlib-lpc port build elf binaries for the tests by passing all the library's .o files to...
... I think I can shed some light on this. The basic problem is that the newlib library you are linking against already has the routines that the newlib-lpc...
Hi Richard, I can't use the LPC22xx due to other constraints... However I have only one device to control via this bus. This device can be configured to work...
Sunil, It depends on your requirement, what you want at each memory. Basically you have the .text (code), .data (initialized data) & .bss (uninitialised data)...
I've bought a Olimex JTAG and after having pacthed it (connected pin 8 & 15) O'm now able to connect to my LPC2138 with OCDRemote. But the problem is, that I'm...
The Windows version of the GNUARM toolchain for the ARM has been updated to 4.0. You can download the source and binary files at http://www.gnuarm.com...
My XTAL freq is 14.7456 MHz Pll factor is 4 -> CPUclk=58,9824MHz PLL div is 2 -> 29,4912MHz VPB div is 4 -> 14.7456MHz But I saw maybe a problem in software,...
I have just tested the P0.10 on my system and it is 3.3V!! I am using LPC2138 Did they fix the P0.10 issue on new chips? Thanks, Gus ... power supply. I'll...
Hi Mike, thanks for your reply.Iam using external memory to place some data and read it whenever necessary. Iam just placing some data and there is no need to...
... In my opinion number 2 will cause you the least problems. In fact I would disable interrupts before modifying VICIntEnable. And yes you have to be in a...

Can't seem to get the RX FIFO on UART0 to work... My setup: U0IER bit 0 =1, Enabled RDA interrupt (receive data interrupt) U0IER bit 1 = 1, Enable THRE...
The standard rand() function of many compilers (Keil, etc.) return pseudorandom integer in range 0 to 32767. 1. Is the period of such pseudorandom generators...
Hi, ... Good question. Usually these implementations are based on linear congruence, i.e next_random = (seed*x+y) modulo a smaller number. ... Try Google,...
Hello, I need to write a nibble to P0.31-P0.28. When I write a value, it is not output correctly: ex. I write 0x7E 5C 38 A1 sequence and I get out 0x7C 4C 38...
