I'm working on a design with an LPC2148. However, the LPC2148 has a long lead-time in the US. So I'm going to use a LPC2138 until the LPC2148 is ready. The obvious difference is the loss of the USB interface. The rest of the device appears to be electrically and software wise the same. (The LPC2138 does have two 10-bit DACs instead of one on the LPC2148). Any other problems or issues ...

I recently switched development boards from the Olimex LPC2138 to the LPC2148. Now it seems that the standard Philips Flash Utility (ver. 2.2.0) that I was using for the LPC2138 does not include the LPC2148 in its supported devices list. What are you using to program the flash on the LPC2148? Is Lpc21isp the only free Win tool for flash programming on the LPC2148? Thanks, Paul

Hi, I have connected the LPC2148 board to the EasyWifi board(the wi-fi module MRF24WB0MA is made by Microchip). I only need to ping a website. I believe that the wifi board simply sends a message but I will have to write the code for the LPC2148. Are there any examples for LPC2148 that connect to wifi that will help me get started ? Thanks ------------------------------------

Hello, excuse my questions which are more USB related than to LPC2148: I want to transfer some data from LPC2148 to PC. My data is a big amount of data. "Jitter" is no problem. In reverse direction (PC -> LPC2148) there is almost no throughput required. There are various endpoints to choose from in LPC2148. Which one should i choose for my application ?

Hi, I am fighting with gcc (version 2008q1 from Codesourcery), the startup code from boot.s, the linker file for LPC2148, FreeRTOS v5.03 and the probably excellent lpc2148 demo (v1.20) from jcwren. 'Probably' because I cannot compile/link it. And that's what I try to fix. The good news: the ARM7_LPC2106_GCC demo compiles just fine. I don't know if it runs (likely after modification o...

Hello i want to use crossworks for arm with a lpc2148 board from embedded artists. 1) Can I use this compiler for lpc2148 because i found no informations on the website. And i also found no sample code for lpc2148 on the sample files. 2) Is difficult to rewrite the sample programs from Phillips (Keil bundle or ARM bundle) to Crossworks? What must i look for. 3) Is the tasking lib...

Hi, In which cases do we need to use pull up or pull down resisters? I need to interface some gates and buffers to the gpio pins of LPC2148 as dead time generator circuit. 1.Is there any dead time register available in LPC2148's PWM module as in case of some Texas instrument's DSPs or will I have to use timers and capture interrupts? 2.how would I know if the logic family I am using is co...

Is it normal for the Philips Flash Utility (2.2.3) to ID a LPC2148 as a LPC2138? I'm using a Olimex LPC-P2148 with a clearly marked and correcly identifyed LPC-2148 part (ID 196389). I know that they have equal amount of ROM & RAM, but since the LPC2148 *do exist* in the dropdown box *i assumed* it would be selected. One other thing.

Hello, i am using a LPC2148 via USB, connected to my PC (under WinXP and libusb-win32, PC has USB 2.0). I am currently trying to understand how i can send data from LPC2148 to PC and increase my throughput. I use the KEIL examples as base for my development (but currently instead of using an interrupt i just do polling and call the interrupt routine by myself,

Hi guys I just came back from Nuernberg and I have some real good news about LPC2148. I spoke to one of the NXP guys and he told me that they will release in Q2/Q3 09 a pin compatible version of the LPC17xx for the LPC2148. They can also be clocked around 100MHz and they will add some more RAM. I hope they will release this one very soon. Best regards Juergen ------------...
