Hellow LPC2000 funs ). I introduce a LPC CMSIS2000 project for LPC2000 series. The goal of project is to make CMSIS like build environment for LPC2000 series MCU. As you know there is official sources from NXP and ARM for new Cortex MCU. This sources is done with CMSIS standart, also there is Peripheral Library for Cortex family controllers.

I have been using the GNU Tools for ARM Embedded Processors for almost a year now on Cortex-M3 parts and I have been pretty happy with it. When using the same tools on smaller Cortex-M0 parts such as the LPC11U24, I have found that I have to be very careful what features I end up pulling in from newlib since it can use up valuable kilobytes. In many cases, the best solution has been just to remo...

We just ran into a strange problem. We've had a product using the LPC2132 for over 5 years now in production. We just bought another batch of chips, ran another production run, and now have a problem never had before to date. - We program the firmware into the MCU using FlashMagic through the UART. - After the firmware is in, we then access the product/MCU again from our own Windows app soft...

Hello friends, I'm working with an LPC2148 with FreeRTOS, and I need to interrupt the MCU with an external interrupt (which could be FIQ or IRQ for instance), and then toggle a pin with a task. Ive been told FreeRTOS have problems calling its API functions from an FIQ. Has someone did something similar? I just need to interrupt the MCU with an external interrupt and then toggle a pin w...

I have Keil uVision software for development and a ULINK 2 for programming via a 20 pin JTAG on the circuit board (LPC2148). What is the easiest approach for initial production programming of these devices on circuit boards (we have SD card updates - but the board must be programmed with a bootloader and production code for the first time)? Meaning, I don't want to include the source f...

Hello, Does somebody has experience with the new Embedded artist development kit EA4357 ? I receive it last week, and if a load precompiled exemples it works perfectly. If I compile all exemples project with no change (Keil v4.60 + last CMSIS version) it compile, I can load them into LPC4357 with J-Link but exemples doesn't works. I just put a scopemeter before FTDI chip and I see output ...

Hello, I've got a working product using a LPC2478 + SDRAM + 7" TFT display (8 bits colors). Now I've got a new project with same LPC2478 but for cost reason we would like to use the internal RAM for the LCD : We use now a 4.3" display (480*272 = 130560 kbyte of RAM in 8 bit depth. The idea is to use 4 bit / pixel (it's enough for this product). I keep the same project changing only the ...

Dear all, I need to use an BMP085 Pressure sensor with my ARM LPC2148. Does someone have or know about some i2c bmp085 C library for the lpc2000? Any help would be appreciated as it would greatly speed up my development process. Best regards, -- * Carlos Apablaza Brito* ------------------------------------

I just got my free sample of the LPC1102 from NXP and it is tiny. I appreciate previous comments about not sneezing. I can't see how a hobbyist would be able to use the chip as is. Pity as I have an application for which it would be ideal. I presume the 16 dots which are the connectors are blobs of solder and these melt onto pads when a PCB with an LPC1102 is heated in an oven. It would be very...
